- Abstract
Extreme rainfall is one of the most severe weather hazards affecting all the globe, especially thetropical region. Some studies use statistical approaches for interpreting extreme events bychoosing a constant threshold based on different empirical rainfall distributions. The main goal ofthis work is to fit different Extreme value distributions (EVDs) like the Generalized Extreme Value(GEV) and Generalized Pareto Distribution (GPD) for extreme rainfall in different time scales tounderstand their behaviour. The objectives of this study are: (i) analyse the extreme precipitationdistribution at 1 degree daily (1DD) using rain gauges data and different well-known satellite-basedretrievals like TAPEER (Tropical Amount of Precipitation with an Estimate of ERrors) over Brazil;(ii) characterize the Mesoscale Convective Systems (MCS) life cycle properties like duration andminimum temperature (among others) associated with extreme events using TOOCAN (TrackingOf Organized Convection through a 3 dimensional segmentatioN) tool.
