Simultaneous occurrences of multiple heatwaves or cold spells in remote geographical regions have drawn considerable attention in the literature due to their potentially far-reaching impacts. We introduce a flexible toolbox to study such concurrent temperature extremes with adjustable parameters that different users can tailor to their specific needs. We then use the toolbox to present a climatological analysis of spatially compounding heatwaves and cold spells in the global midlatitudes. Specific geographical areas, such as western Russia, central Europe, southwestern Eurasia and western North America, emerge as hotspots for concurrent temperature extremes. Concurrent heatwaves are becoming more frequent, longer-lasting and more extended in the Northern Hemisphere, while the opposite holds for concurrent cold spells. Concurrent heatwaves in the Southern Hemisphere are comparatively rare but have been increasing in both number and extent. Notably, several of these trends in concurrent temperature extremes are significantly stronger than the corresponding trends in all temperature extremes.

[Abstract] Understanding the environmental response to the last glacial termination in regions located in transitional climate zones such as the Atlantic Iberian mountains is crucial to estimate potential changes in regions affected by current glacial melting. We present an 8.5 m-long, solid last deglaciation and Holocene chronostratigraphic record including detailed sediment analysis from Lake Peixão, a pro-glacial lake in the Serra da Estrela (Central Portugal). The age–depth model relies on a Bayesian approach that includes 16 AMS 14C dates and 210Pb–137CS measurements, robustly dating the lake formation at 14.7 ± 0.32 cal. ka BP. This chronological reconstruction shows an average sedimentation rate of ca. 0.07 cm yr−1 (15 yr cm−1), enabling proxy analyses at decadal timescales. The sediment sequence is composed of five lithological units: (U1) coarse and unsorted fluvioglacial lacustrine deposits; (U2) massive fluvioglacial lacustrine deposits (863–790 cm below surface [bsf]; 14.7 ± 0.32–13.8 ± 0.12 cal. ka BP); (U3) water current fluvioglacial lacustrine deposits (790–766 cm bsf; 13.8 ± 0.12–12.9 ± 0.29 cal. ka BP); (U4) laminated/banded lacustrine deposits characterized by terrigenous deposits from ice-covered lake periods and episodic events of ice and snow melting (766–752 cm bsf; 12.9 ± 0.29–11.7 ± 0.15 cal. ka BP); and (U5) massive muddy lacustrine deposits (752–0 cm bsf; 11.7 ± 0.15 cal. ka BP–present). The occurrence of U2 to U4 deposits defines the transition from glacial cold (U1) to net warm postglacial conditions (U5). These climate transitions are marked by changes in sediments and the presence of very low sedimentation rate periods, possibly related to the Intra-Allerød Cold Period and the coldest phase of the Younger Dryas. Our results support the previously proposed timing of the retreat of the Serra da Estrela glaciers ca. 13.8 ± 0.12 cal. ka BP.

Communication latency has become one of the determining factors for the performance of parallel clusters. To design low-latency network topologies for high-performance computing clusters, we optimize the diameters, mean path lengths, and bisection widths of circulant topologies. We obtain a series of optimal circulant topologies of size $2^5$ through $2^{10}$ and compare them with torus and hypercube of the same sizes and degrees. We further benchmark on a broad variety of applications including effective bandwidth, FFTE, Graph 500 and NAS parallel benchmarks to compare the optimal circulant topologies and Cartesian products of optimal circulant topologies and fully connected topologies with corresponding torus and hypercube. Simulation results demonstrate superior potentials of the optimal circulant topologies for communication-intensive applications. We also find the strengths of the Cartesian products in exploiting global communication with data traffic patterns of specific applications or internal algorithms.

Compound weather and climate events are combinations of climate drivers and/or hazards that contribute to societal or environmental risk. Studying compound events often requires a multidisciplinary approach combining domain knowledge of the underlying processes with, for example, statistical methods and climate model outputs. Recently, to aid the development of research on compound events, four compound event types were introduced, namely (a) preconditioned, (b) multivariate, (c) temporally compounding, and (d) spatially compounding events. However, guidelines on how to study these types of events are still lacking. Here, we consider four case studies, each associated with a specific event type and a research question, to illustrate how the key elements of compound events (e.g., analytical tools and relevant physical effects) can be identified. These case studies show that (a) impacts on crops from hot and dry summers can be exacerbated by preconditioning effects of dry and bright springs. (b) Assessing compound coastal flooding in Perth (Australia) requires considering the dynamics of a non-stationary multivariate process. For instance, future mean sea-level rise will lead to the emergence of concurrent coastal and fluvial extremes, enhancing compound flooding risk. (c) In Portugal, deep-landslides are often caused by temporal clusters of moderate precipitation events. Finally, (d) crop yield failures in France and Germany are strongly correlated, threatening European food security through spatially compounding effects. These analyses allow for identifying general recommendations for studying compound events. Overall, our insights can serve as a blueprint for compound event analysis across disciplines and sectors., Hydraulic Structures and Flood Risk

The purpose of this study was to verify if the practice of Yoga influences mindfulness by sociodemographic variables, gender, age, years of practice, volume of practice, and teaching of Yoga. The participants were 281 adults aged from 18 to 90 years old, 81% women and 19% men (214 yoga practitioners, and 67 non-practitioners. The version of the Mindfulness Questionannaire (FFMQ) (Baer, Smith, Krietemeyer, & Toney, 2006) proposed by Ramos, Rosado, Serpa, Cangas, Gallego, & Ramos (2017) was used. This assesses four dimensions: to Observe, Not to Judge, to Describe, and to Act Consciously. Data analysis was carried out with the Statistic Program SPSS 25.0. The results indicate the existence of significant differences in several dimensions of Mindfulness. In the dimension to Observe, Yoga practitioners showed significantly higher scores than non-practitioners. Regarding Yoga teachers, those who practice displayed higher values in the dimension to Observe, but lower values in the dimension to Act Consciously. Women presented a specific behavior, different than men, practitioners, or non-practitioners. In the dimension Not to Judge, there were significant differences by age, with higher scores in practitioners aged 60 years old or more. The practice of Yoga may contribute to a higher level of Mindfulness, yet further research is necessary considering the multidimensionality of the studied construct., O objetivo deste estudo foi verificar se a prática de Yoga influencia a Atenção Plena, em função das variáveis sociodemográficas género, idade, anos de prática, volume de prática e lecionação de Yoga. Os participantes foram 281 adultos, entre 18 e 90 anos, 81% mulheres e 19% homens, (214 praticantes de Yoga e 67 não praticantes). Aplicou-se o Questionário de Atenção Plena (FFMQ) (Baer, Smith, Krietemeyer, e Toney, 2006) na versão de Ramos, Rosado, Serpa, Cangas, Gallego, e Ramos (2017), que avalia quatro dimensões: Observar, Não Julgar, Descrever e Agir Conscientemente. Para analisar os dados utilizou-se o programa estatístico SPSS 25.0. Os resultados apontam para a existência de diferenças significativas em diversas dimensões da Atenção Plena. Na dimensão Observar os praticantes de Yoga apresentam diferenças significativas favoráveis aos praticantes. Considerando exclusivamente os praticantes evidenciouse valores superiores na dimensão Observar para aqueles com mais de doze anos de prática e com maior volume semanal. No volume de prática os praticantes com maior volume apresentam também valores mais elevados no Agir Conscientemente. Considerando os professores de Yoga, relativamente aos praticantes, estes apresentaram valores superiores na dimensão Observar mas menor na dimensão Agir Conscientemente. As mulheres apresentam um comportamento específico, diferente dos homens, quer praticantes quer não praticantes. Na dimensão Não Julgar existem diferenças significativas quando se considera a idade, distinguindo-se praticantes com mais de 60 anos. Concluiu-se que a prática de Yoga pode contribuir para o aumento da Atenção Plena mas que a investigação deve continuar atendendo à multidimensionalidade do construto em causa., El objetivo de este estudio fue verificar si la práctica del yoga influye en la Atención Plena, dependiendo de las variables sociodemográficas género, edad, años de práctica, volumen de práctica y enseñanza del yoga. Los participantes fueron 281 adultos, entre 18 y 90 años, 81% mujeres y 19% hombres, (214 practicantes de yoga y 67 no practicantes). El cuestionario de Atención Plena (FFMQ) (Baer, Smith, Krietemeyer, y Toney, 2006) se aplicó en la versión de Ramos, rosado, Serpa, Cangas, Gallego, y Ramos (2017), que evalúa cuatro dimensiones: Observar, No Juzgar, Describir y Actuar Conscientemente.

En el volumen de la práctica, los practicantes con mayor volumen también tienen valores más altos en Actuar Conscientemente. Teniendo en cuenta los profesores de Yoga, con respecto a los practicantes, presentaron valores más altos en la dimensión observar pero más pequeño en la dimensión Actúar Conscientemente. Las mujeres presentan un comportamiento específico, diferente de los hombres practicantes o no practicantes. En la dimensión No Juzgando hay diferencias significativas al considerar la edad, distinguiendo a practicantes con más de 60 años.

Compound weather and climate events describe combinations of multiple climate drivers and/or hazards that contribute to societal or environmental risk. Although many climate-related disasters are caused by compound events, the understanding, analysis, quantification and prediction of such events is still in its infancy. In this Review, we propose a typology of compound events and suggest analytical and modelling approaches to aid in their investigation. We organize the highly diverse compound event types according to four themes: preconditioned, where a weather-driven or climate-driven precondition aggravates the impacts of a hazard; multivariate, where multiple drivers and/or hazards lead to an impact; temporally compounding, where a succession of hazards leads to an impact; and spatially compounding, where hazards in multiple connected locations cause an aggregated impact. Through structuring compound events and their respective analysis tools, the typology offers an opportunity for deeper insight into their mechanisms and impacts, benefiting the development of effective adaptation strategies. However, the complex nature of compound events results in some cases inevitably fitting into more than one class, necessitating soft boundaries within the typology. Future work must homogenize the available analytical approaches into a robust toolset for compound-event analysis under present and future climate conditions.

The summers of 2018 and 2019 were characterized by unusually warm conditions over Europe. Here, we describe the intense heatwaves striking the Iberian Peninsula in early August 2018 and late June 2019. The 2018 episode was relatively short-lived but outstanding in amplitude, particularly in western Iberia. Similar to previous mega-heatwaves, the 2019 event was long-lasting and affected large areas of western and central Europe, including eastern Iberia. During these events, many absolute temperature records were broken in western and eastern Iberia, respectively (some of them standing since 2003). In both cases, a cyclonic circulation off the coast in the northeastern Atlantic and a strong subtropical ridge pattern over the affected area promoted the advection of an anomalously warm air mass. This paper highlights the role of these very warm, stable and dry air intrusions of Saharan origin in the western and eastern Iberia heatwave events. Using a thermodynamical classification based on the geopotential height thickness and potential temperature, we show how the magnitude and poleward extension of these Saharan intrusions were unprecedented in the period since 1948. The relationship between Iberian heatwaves and Saharan warm air intrusions is discussed in the long-term context, showing a closer link in southern sectors of the Peninsula. However, a consistent poleward trend in the latitudinal extension of these subtropical intrusions reveals their increasing relevance for heatwaves in northern sectors of Iberia and western Europe. This overall trend is accompanied by an apparent “see-saw” in the occurrence of subtropical intrusions between eastern and western Iberia on multi-decadal scales.

We propose that clusters interconnected with network topologies having minimal mean path length will increase their overall performance for a variety of applications. We approach our heuristic by constructing clusters of up to 36 nodes having Dragonfly, torus, ring, Chvatal, Wagner, Bidiakis and several other topologies with minimal mean path lengths and by simulating the performance of 256-node clusters with the same network topologies. The optimal (or sub-optimal) low-latency network topologies are found by minimizing the mean path length of regular graphs. The selected topologies are benchmarked using ping-pong messaging, the MPI collective communications, and the standard parallel applications including effective bandwidth, FFTE, Graph 500 and NAS parallel benchmarks. We established strong correlations between the clusters' performances and the network topologies, especially the mean path lengths, for a wide range of applications. In communication-intensive benchmarks, clusters with optimal network topologies out-perform those with mainstream topologies by several folds. It is striking that a mere adjustment of the network topology suffices to reclaim performance from the same computing hardware.

The Atmospheric River Tracking Method Intercomparison Project (ARTMIP) is an international collaborative effort to understand and quantify the uncertainties in atmospheric river (AR) science based on detection algorithm alone. Currently, there are many AR identification and tracking algorithms in the literature with a wide range of techniques and conclusions. ARTMIP strives to provide the community with information on different methodologies and provide guidance on the most appropriate algorithm for a given science question or region of interest. All ARTMIP participants will implement their detection algorithms on a specified common dataset for a defined period of time. The project is divided into two phases: Tier 1 will utilize the MERRA-2 reanalysis from January 1980 to June of 2017 and will be used as a baseline for all subsequent comparisons. Participation in Tier 1 is required. Tier 2 will be optional and include sensitivity studies designed around specific science questions, such as reanalysis uncertainty and climate change. High resolution reanalysis and/or model output will be used wherever possible. Proposed metrics include AR frequency, duration, intensity, and precipitation attributable to ARs.

The Atmospheric River Tracking Method Intercomparison Project (ARTMIP) is an international collaborative effort to understand and quantify the uncertainties in atmospheric river (AR) science based on detection algorithm alone. Currently, there are many AR identification and tracking algorithms in the literature with a wide range of techniques and conclusions. ARTMIP strives to provide the community with information on different methodologies and provide guidance on the most appropriate algorithm for a given science question or region of interest. All ARTMIP participants will implement their detection algorithms on a specified common dataset for a defined period of time. The project is divided into two phases: Tier 1 will utilize the MERRA-2 reanalysis from January 1980 to June of 2017 and will be used as a baseline for all subsequent comparisons. Participation in Tier 1 is required. Tier 2 will be optional and include sensitivity studies designed around specific science questions, such as reanalysis uncertainty and climate change. High resolution reanalysis and/or model output will be used wherever possible. Proposed metrics include AR frequency, duration, intensity, and precipitation attributable to ARs.

The explosive cyclogenesis of extratropical cyclones and the occurrence of atmospheric rivers are characteristic features of a baroclinic atmosphere, and are both closely related to extreme hydrometeorological events in the mid-latitudes, particularly on coastal areas on the western side of the continents. The potential role of atmospheric rivers in the explosive cyclone deepening has been previously analysed for selected case studies, but a general assessment from the climatological perspective is still missing. Using ERA-Interim reanalysis data for 1979–2011, we analyse the concurrence of atmospheric rivers and explosive cyclogenesis over the North Atlantic and North Pacific basins for the extended winter months (ONDJFM). Atmospheric rivers are identified for almost 80% of explosive deepening cyclones. For non-explosive cyclones, atmospheric rivers are found only in roughly 40% of the cases. The analysis of the time evolution of the high values of water vapour flux associated with the atmospheric river during the cyclone development phase leads us to hypothesize that the identified relationship is the fingerprint of a mechanism that raises the odds of an explosive cyclogenesis occurrence and not merely a statistical relationship. These new insights on the relationship between explosive cyclones and atmospheric rivers may be helpful to a better understanding of the associated high-impact weather events.

Atmospheric blocking episodes are an important component of the intra-seasonal and interannual variability at mid-latitudes. Their impacts in the European continent, and in particular, in the Mediterranean basin, depend on: i) blocking location; ii) spatial characteristics; iii) temporal length. A characterization of Euro-Atlantic blocking occurrence within different sectors (Atlantic, European and Russian) was performed, focusing on the impacts in temperature and precipitation regimes. High-latitude blocks were distinguished from sub-tropical ridges using a novel ridge detection scheme. Ridges do not require wave-breaking occurrence as blockings do, although they are frequent precursors of wave-breaking and subsequent high-latitude blocking episodes. The distinct seasonal and regional impacts associated with different blocking/ridge locations were analyzed, as well as the dynamical mechanisms driving the temperature and precipitation responses associated to each pattern, namely: the role of cyclonic activity; moisture transport; large-scale atmospheric instability; balances between horizontal advection, subsidence and radiation budgets. Our analysis clarifies that increasing extreme heat episodes in southern Europe and Mediterranean areas should not be attributed to blockings, but rather to sub-tropical ridges. In northern Europe, both regimes are responsible for warm conditions in summer, due to enhanced radiative heating and increased subsidence. Opposite temperature responses are found for winter blocking/ridges. While blockings reinforce cold northerly advection and foster cold spells, ridge patterns are related with mild Atlantic flows associated. An opposite north-south dipole is also found regarding precipitation anomalies. While blocks force a split of the Jetstream and storm-track, ridges are characterized by a stronger zonal flow at higher latitudes. Accordingly, negative (positive) precipitation anomalies during blocks occur at higher (lower) latitudes.

The authors gratefully acknowledge the NOAA Air Resources Laboratory (ARL) for the provision of the HYSPLIT transport and dispersion model and/or READY website (http://www.ready.noaa.gov) used in this publication., In this work we performed an analysis on the impacts of blocking episodes on seasonal and annual European precipitation and the associated physical mechanisms. Distinct domains were considered in detail taking into account different blocking center positions spanning between the Atlantic and western Russia. Significant positive precipitation anomalies are found for southernmost areas while generalized negative anomalies (up to 75 % in some areas) occur in large areas of central and northern Europe. This dipole of anomalies is reversed when compared to that observed during episodes of strong zonal flow conditions. We illustrate that the location of the maximum precipitation anomalies follows quite well the longitudinal positioning of the blocking centers and discuss regional and seasonal differences in the precipitation responses. To better understand the precipitation anomalies, we explore the blocking influence on cyclonic activity. The results indicate a split of the storm-tracks north and south of blocking systems, leading to an almost complete reduction of cyclonic centers in northern and central Europe and increases in southern areas, where cyclone frequency doubles during blocking episodes. However, the underlying processes conductive to the precipitation anomalies are distinct between northern and southern European regions, with a significant role of atmospheric instability in southern Europe, and moisture availability as the major driver at higher latitudes. This distinctive underlying process is coherent with the characteristic patterns of latent heat release from the ocean associated with blocked and strong zonal flow patterns. We also analyzed changes in the full range of the precipitation distribution of several regional sectors during blocked and zonal days. Results show that precipitation reductions in the areas under direct blocking influence are driven by a substantial drop in the frequency of moderate rainfall classes.

Este artigo tem como objetivo analisar o quantitativo e volume financeiro dos projetos de ensino, pesquisa e extensão, firmados pelas Fundações de Apoio no âmbito dos Centros de Ensino da UFSC, durante o ano de 2015. A pesquisa caracteriza-se como descritiva, bibliográfica e documental, com abordagem qualitativa e quantitativa. A partir do levantamento das informações disponibilizadas pelas quatro Fundações de Apoio da UFSC foram analisados os projetos gerenciados em cada uma delas, seus respectivos valores, suas áreas de atuação - entre ensino, pesquisa e extensão e as distribuições destes pelos Centros de Ensino da instituição. A análise dos dados demonstrou que a UFSC se destaca na área da pesquisa em campos como a tecnologia e inovação e na extensão em áreas como a saúde e a tecnologia. No que tange aos recursos financeiros, observa-se que há concentração de projetos e movimentação de recursos em três Fundações de Apoio de forma homogênea. Esta característica persiste na alocação dos recursos por Centro de Ensino, assim como no montante de recursos destinados a projetos de extensão.

Blocking high pressure systems are large-scale atmospheric circulation patterns with meteorological impacts that vary across regions and seasons, depending on the blocking location, spatial characteristics and temporal length. Blocking episodes are an important component of the intra-seasonal and inter-annual variability at mid-latitudes. We performed a thorough characterization of Euro-Atlantic blocking occurrence within different longitudinal sectors (Atlantic, European and Russian), and a comprehensive analysis of their seasonal and regional impacts in temperature and in precipitation regimes. In order to distinguish high-latitude blocking from other common high pressure systems affecting Europe, namely sub-tropical ridges, a novel ridge detection scheme was developed. Ridges do not require a wave-breaking occurrence as blockings do, although they are frequent precursors of wave-breaking and subsequent blockings. Thus, a novel characterization of the distinctive seasonal impacts associated with sub-tropical ridges occurring in different longitudinal sectors of the Euro-Atlantic region was performed. Finally, an assessment of the dynamical mechanisms behind the temperature and precipitation responses to blocking was performed. This includes for precipitation the role of cyclonic activity (storm-tracks and cut-off lows), moisture transport, and large-scale atmospheric instability, while for temperature the focus was on the role played by horizontal advection, subsidence and imbalances in various radiation budgets. This distinction clarifies that most extreme heat episodes in southern Europe and Mediterranean areas should not be attributed to blockings, but rather to ridges. In central and northern European areas, both regimes are responsible for warm conditions in summer, due to enhanced radiative heating and increased subsidence. During winter, blocking and ridges lead to opposite temperature responses. Blocks reinforce cold northerly advection in their eastern fl

A family of graphs optimized as the topologies for supercomputer interconnection networks is proposed. The special needs of such network topologies, minimal diameter and mean path length, are met by special constructions of the weight vectors in a representation of the symplectic algebra. Such theoretical design of topologies can conveniently reconstruct the mesh and hypercubic graphs, widely used as today's network topologies. Our symplectic algebraic approach helps generate many classes of graphs suitable for network topologies.

Atmospheric Rivers (ARs) are elongated bands of high water vapor concentration extending to the midlatitudes, which can be associated with intense precipitation and floods over continental areas. We analyze ARs reaching Europe in simulations from six Coupled Model Intercomparison Project Phase 5 (CMIP5) global climate models (GCMs) to quantify possible changes during the current century, with emphasis in five western European prone coastal areas. ARs are represented reasonably well in GCMs for recent climate conditions (1980-2005). Increased vertically integrated horizontal water transport is found for 2074-2099 (RCP4.5 and RCP8.5) compared to 1980-2005, while the number of ARs is projected to double on average for the same period. These changes are robust between models and are associated with higher air temperatures and thus enhanced atmospheric moisture content, together with higher precipitation associated with extratropical cyclones. This suggests an increased risk of intense precipitation and floods along the Atlantic European Coasts from the Iberian Peninsula to Scandinavia.

This study deals with the question of how winegrowing in Spain may be altered by anthropogenic climate change. The present state and expected future development of three bioclimatic indices relevant for winegrowing were assessed by observation, and four regional climate models from the EU-ENSEMBLES project were investigated. When comparing the 2061–2090 scenario period to the 1961–1990 reference period, the models unanimously indicate a significant increase in the mean of the two considered thermal indices over the entire study region. However, for the index based on temperature and precipitation, the models are heavily biased when verified against observations and generally disagree on the size of the projected future change. For this index, unanimous model agreement was only found for northwestern Spain where all models indicated a significant decrease in the mean. From these results, regional climate change is expected to negatively affect the quality of wine in the growing regions of central and southern Spain, and the Ebro valley, whereas positive effects should be expected in the northwest. No significant changes in the risk of mildew infestation are to be expected except for the northwest, where this risk is projected to decrease.

In this work we reassess the impacts of blocking patterns on precipitation regimes in the Iberian Peninsula, distinguishing between north Atlantic and European blocking. For this we take full advantage of the recently developed high-resolution datasets for the Iberian countries. Precipitation anomalies during blocking events obtained with this dataset allow a much finer regional characterization of the impacts in both average and extreme daily precipitation, particularly when compared to widely used low-resolution reanalysis datasets. Blocked patterns induce a negative-positive dipole of precipitation anomalies from northwest to southeast Iberia. Increases are widespread during Atlantic blocks and pronounced in southern and eastern areas of Iberia, while during European blocks they are more spatially restricted, with increases above 50 % in coastal Mediterranean areas, which represents a considerable fraction of the annual precipitation. Blocking impacts in precipitation are nearly opposite to those found during strong zonal flow situations, but there are also some asymmetries in the precipitation responses. A significant increase in cyclones and cut-off lows frequency southwards of blocking structures is related to precipitation excesses over southern and eastern areas, where dynamical factors and local processes play a crucial role. On the contrary, precipitation deficits in northwest Iberia during blocking episodes are better explained by a reduction in north Atlantic frontal activity and simultaneous decreases in large-scale moisture advection towards northern Iberia. We show that these anomalies during blocking result from changes in precipitation amount rather than from increases in rainy days, pointing to more extreme rainfall regimes, particularly in southeastern Iberia. Finally, an Extreme Value Analysis was performed, fitting Generalized Pareto Distributions to precipitation extremes. Results show that the different extreme precipitation regimes of northwe

The article pays homage to the 40th anniversary of Hélgio Trindade’s book Integralismo: o fascismo brasileiro na década de 1930 (published in 1974), a classical work for the studies on Brazilian Integralist Action (AIB), by engaging in a critique of the book’s main thesis reception by the Integralism researchers. It argues that Trindade’s hypothesis was vulgarized and is currently being taken for granted. Thus, it seeks to show that one of the consequences of the “fascist thesis” uncritical reception has not only obstructed more detailed analysis capable of capturing the multiple aspects of the integralist movement, but also made it a stranger in its own land by ignoring, for example, the deep relations between AIB and the Brazilian intellectual context, which was crucial for its political and cultural project’ development and for guiding its practices and actions. Finally, the article intends to provide a critique of how the studies and researches about the Integralism are being made from a crystallized and naturalized view of this political movement., O artigo buscar prestar uma homenagem pelos quarenta anos da publicação do livro Integralismo: o fascismo brasileiro na década de 30 (1974), de Hélgio Trindade, obra clássica para o estudo da Ação Integralista Brasileira (AIB), por meio de uma reflexão crítica sobre a recepção de sua tese central por parte dos pesquisadores do Integralismo. Argumenta-se, assim, que a hipótese de Trindade – de que a AIB seria um fascismo brasileiro – foi vulgarizada ao ponto de naturalizar-se, constituindo-se em algo dado. A partir daí, busca-se mostrar que uma das principais consequências da recepção passiva e acrítica da “tese fascista” não apenas impediu uma análise mais matizada, capaz de dar conta da complexidade do movimento integralista em seus múltiplos aspectos, como também o transformou em um estrangeiro em sua própria terra, descurando das profundas relações da AIB com o contexto intelectual brasileiro que forneceu os elementos imprescindíveis para a formulação das ideias integralistas e para a orientação de suas práticas e ações. Em última análise, o artigo pretende fornecer uma crítica ao modo como os estudos e pesquisas sobre o Integralismo têm se organizado a partir de uma visão cristalizada e naturalizada do mesmo.
