The North East (NE) region of India is prone to severe thunderstorm during pre monsoon period. These premonsoon precipitations are measured at Guwahati (26 17’ N, 91 77’ E) using a laser based particle size and velocity (PARSIVEL) disdrometer from 15 April to 31 May 2010 under a national field campaign named Severe Thunderstorm Observational and Regional Modeling (STORM). For the improved under...

The paper presents results concerning the changes in the content of aldehydes in samples of lake water collected near the lake surface. The study of lake waters was undertaken to explain which physicochemical parameters of the environment have the greatest influence on the level of aldehydes, which of the aldehydes are most often met in surface water and in what concentrations. We observed that...

OBJECTIVE To determine the distribution of Aedes albopictus (Skuse) in Nuevo Leon between 2001 and 2004. MATERIAL AND METHODS Standardized methods were used to collect 6371 samples of mosquito's larvae from 167 sites. The proportions of samples positive for Ae. albopictus were obtained by municipality and year, using the software program Excel. RESULTS There were 1179 samples positive for A...

The occurrence of extreme precipitation events is now a serious concern in recent years Japan. This study explores the atmospheric driving mechanisms two occurred during 5–6 July 2017 and 5–8 2018 over western We identified that transport large amounts moisture wind streams with speed minimum 15 m s?1 from south Japan towards north on days before these torrential are mainly responsible for floo...

Various ammonium sulfate concentrations and reaction conditions were employed in the fractionation of sera from rabbits, sheep, horses, and goats. Precipitates and supernatant fluids were analyzed by electrophoresis to study the effects of the controlled variables. At room temperature, the third precipitate in 35% saturated (NH(4))(2)SO(4) was the best fraction from both rabbit and sheep sera; ...

The performance of single models and ensemble prediction systems has been investigated with respect to quantitative precipitation forecasts. Evaluation is based on the potential economic value of +72 h/+96 h forecasts. The verification procedure consists of taking into account all precipitation amounts that are predicted in the vicinity of an observation in order to compute spatial, multi-event...
