Some of the most intense thunderstorms in the world take place in central and northern Argentina, and their start and development is strongly influenced by the orography of the Andes and sierras de Coórdoba. These thunderstorms are associated with the occurrence of severe weather phenomena that generate important material damages and economic loss in rural and urban areas. The aim of this paper was to do the observational study of the spatial and temporal distribution of different severe weather phenomena, in particular, hail, intense rain and strong winds with gusts. Most of these events took place between the evening and midnight, and also between late Spring and early Summer. At the same time, while studying the occurrence of hail, it was found that its density of accumulation decreased as its diameter increased. [ABSTRACT FROM AUTHOR]

In this paper l want to present a synthesis of the ethnohistorical and archaeological data referring to the Chichas of the Southcentral Andes, offering an integral view of its territorial and temporal development. The main question that guides me throughout this article is the supposed continuity between the ethnohistoric Chichas group, known from written sources of the 16th century. and the archaeological "style" often associated with them and dated preliminary between 600 and 1500 A.D, To present a broader picture of the Chichas culture it is necessary to review both data sets and question this supposed "cultural continuity" which leads to the idea of a territory of Chicha influence which is characterized by its heterogenous relations between the different entities that habitated this area, relations which, far from being static during time and space. represent a diverse panorama of human interrelationships.
