Non-Hodgkin lymphomas are malignant neoplasms whose incidence rates increase each year. These also include neoplasms rare in the general population. The present case report described a patient with lymphoplasmacytic lymphoma (LPL) and rapid liver damage. In most cases, infiltration of the liver is rare in advanced stages of hematopoietic malignancies when hepatomegaly, cholestatic jaundice and organ failure are observed. The patient’s history includes non-specific abdominal pain that was accompanied by general symptoms such as nocturnal hyperhidrosis, subfibrile temperature and fever, as well as weight loss. The above complaints aggravate with an increase in organ size. The laboratory findings initially demonstrated moderately elevated concentrations of transaminases. In our case, the baseline biochemical indices of liver function were found to be normal. During the next days of hospitalisation, the features of liver damage intensified and were accompanied by liver failure. The gold diagnostic standard is a biopsy of the bone marrow and the organ affected. Since the patient’s condition deteriorated and liver failure developed, the diagnosis was established based on trephine biopsy of the bone marrow. Chemotherapy was implemented; despite the treatment applied, the patient’s clinical condition did not improve. Two months after the onset of first symptoms the patient died.

This paper presents a multimodel assessment of fidelity in representation of the diurnal cycle of precipitation over the Maritime Continent (MC). Daily mean precipitation rate and amplitude and phase of the diurnal cycle are utilized to validate General Circulation Model (GCM) performance with respect to multiyear annual mean and seasonal cycle. The analysis shows that models' 6‐hourly temporal resolution and 2.5° spatial resolution is sufficient to depict key characteristic of diurnal precipitation. Results show that most models are sensitive to the existence of the MC and show different characteristics of subdaily precipitation. However, 19 out of 20 models underestimate the daily mean precipitation over the eastern Indian Ocean and most of them underestimate both daily mean precipitation and amplitude of the diurnal cycle, especially over islands within the region. Observations show that within the MC the diurnal cycle is higher over land than over ocean. Many models decrease this land‐sea contrast. Most models recognize difference in phase of the diurnal cycle between MC islands and surrounding ocean, but some of them show opposite phasing of the diurnal cycle. Results show that modern models perform better than past generation, sometimes comparably to regional models' run in much higher resolution. Although models perform well with respect to the seasonal cycle of the daily mean precipitation, they fail to realistically represent the seasonal evolution of the diurnal cycle amplitude. Additionally, models show no coherence in land‐ocean contrast derived from a multiyear average of daily mean precipitation and amplitude of the diurnal cycle.

Convectively coupled Kelvin waves (CCKWs) are a major component of the tropical atmospheric circulation, propagating eastward around the equatorial belt. Here we show that there are scale interactions between CCKWs and the diurnal cycle over the Maritime Continent. In particular, CCKW packets that pass a base point in the eastern Indian Ocean at 90°E between 0600 and 0900 UTC subsequently arrive over Sumatra in phase with the diurnal cycle of convection. As the distance between Sumatra and Borneo is equal to the distance traveled by a CCKW in 1 day, these waves are then also in phase with the diurnal cycle over Borneo. Consequently, this subset of CCKWs has a precipitation signal up to a factor of 3 larger than CCKWs that arrive at other times of the day and a 40% greater chance of successfully traversing the Maritime Continent.

Convectively coupled Kelvin waves (CCKWs) are atmospheric weather systems that propagate eastward along the equatorial wave guide with phase speeds between 11 and 14 m s−1. They are an important constituent of the convective envelope of the Madden‐Julian oscillation (MJO), for which ocean‐atmosphere interactions play a vital role. Hence, ocean‐atmosphere interactions within CCKWs may be important for MJO development and prediction and for tropical climate, in general. Although the atmospheric structure of CCKWs has been well studied, their impact on the underlying ocean is unknown. In this paper, the ocean‐atmosphere interactions in CCKWs are investigated by a case study from November 2011 during the CINDY/DYNAMO field experiment, using in situ oceanographic measurements from an ocean glider. The analysis is then extended to a 15 year period using precipitation data from the Tropical Rainfall Measuring Mission and surface fluxes from the TropFlux analysis. A methodology is developed to calculate trajectories of CCKWs. CCKW events are strongly controlled by the MJO, with twice as many CCKWs observed during the convectively active phase of the MJO compared to the suppressed phase. Coherent ocean‐atmosphere interaction is observed during the passage of a CCKW, which lasts approximately 4 days at any given longitude. Surface wind speed and latent heat flux are enhanced, leading to a transient suppression of the diurnal cycle of sea surface temperature (SST) and a sustained decrease in bulk SST of 0.1°C. Given that a typical composite mean MJO SST anomaly is of the order of 0.3°C, and more than one CCKW can occur during the active phase of a single MJO event, the oceanographic impact of CCKWs is of major importance to the MJO cycle. Passage of a CCKW is associated with coherent atmosphere‐ocean interactions that last about 4 daysUpper ocean temperature diurnal cycle is suppressed and bulk SST is decreased during CCKW eventAir‐sea interactions during CCKW passage are substantial contributor to intraseasonal variability

Atmospheric convectively coupled equatorial Kelvin waves (CCKWs) are a major tropical weather feature strongly influenced by ocean–atmosphere interactions. However, prediction of the development and propagation of CCKWs remains a challenge for models. The physical processes involved in these interactions are assessed by investigating the oceanic response to the passage of CCKWs across the eastern Indian Ocean and Maritime Continent using the NEMO ocean model analysis with data assimilation. Three‐dimensional life cycles are constructed for “solitary” CCKW events. As a CCKW propagates over the eastern Indian Ocean, the immediate thermodynamic ocean response includes cooling of the ocean surface and subsurface, deepening of the mixed layer depth, and an increase in the mixed layer heat content. Additionally, a dynamical downwelling signal is observed two days after the peak in the CCKW westerly wind burst, which propagates eastward along the Equator and then follows the Sumatra and Java coasts, consistent with a downwelling oceanic Kelvin wave with an average phase speed of 2.3 m s−1. Meridional and vertical structures of zonal velocity anomalies are consistent with this framework. This dynamical feature is consistent across distinct CCKW populations, indicating the importance of CCKWs as a source of oceanic Kelvin waves in the eastern Indian Ocean. The subsurface dynamical response to the CCKWs is identifiable up to 11 days after the forcing. These ocean feedbacks on time scales longer than the CCKW life cycle help elucidate how locally driven processes can rectify onto longer time‐scale processes in the coupled ocean–atmosphere system. We investigate the effects that the passage of a weather system (an atmospheric convectively coupled equatorial Kelvin wave, CCKW) along the Equator has in the eastern Indian Ocean. CCKWs can intensify precipitation and cause extreme weather, such as flooding, over the islands of the Maritime Continent, which include Indonesia and Malaysia. CCKWs affect the ocean and which can then feedback onto the CCKWs. A better understanding of the physical processes connecting the atmosphere and ocean during a CCKW passage is still needed to improve its prediction by models. More accurate CCKW prediction will then help to mitigate some of the consequences of the weather‐related natural disasters in the region. We show that the effects of the passage of the CCKW on the ocean are relatively long‐lived. For example, the increase in the amount of heat available at the ocean surface is maintained for several days after the CCKW has passed. We also show that CCKWs are also capable of triggering dynamic processes in the ocean that can influence precipitation over the islands at a later time. These results show that CCKWs can influence oceanic and weather conditions after their passage and in remote areas, such as coastal regions.
