SUMMARY:

Extreme weather events are one of the most environmental topics studying about climate change. For this reason it is emphasized that research focused on studies on cloud microphysics is essential for climate studies, especially for precipitation extremes. Because these extremes can generate environmental damage that affects the society. Therefore, it is proposed to evaluate the microphysical parameters of clouds causing extreme precipitation events in five sub-regions of northeastern Brazil, taking into account hot and cold clouds. Therefore, data from two products of the satellite Tropical Rainfall Measuring Mission (TRMM), 2ACLIM and 2A25 from Microwave Imager (MI) and Precipitation Radar (PR) sensors, respectively, were used for this study. The parameters to be analyzed from these sensors are: integrated content of liquid water in the cloud (kg/m²), integrated ice content (kg/m²), surface precipitation rate (mm/h), freezing level Height (m) and Rainfall type. To analyze the microphysical parameters of extreme precipitation clouds in northeastern Brazil, it is intended to use statistical methods and measures such as mean, standard deviation, confidence interval, variance analysis, Tukey, Kruskal-Wallis and Dunn tests. These will verify whether there is statistical difference between the means of the microphysical parameters of the clouds generating extreme precipitation between seasonal periods of each sub-region and between the sub-regions. Finally, it is intended to present an empirical model to characterize the cloud microphysics responsible for extreme precipitation events in northeastern Brazil.
