First INTEXseas results on ‘Defining extreme rainy seasons: methodology and insights into extremeness and persistence’ by Emmanouil Flaounas, Michael Sprenger and Heini Wernli will be presented his at EGU in Vienna as a poster presentation on Wednesday, 10 April at 14.00 in Hall X5, in the session ‘The atmospheric water cycle: processes, dynamics and characteristics’. This work proposes and illustrates an objective definition of extreme rainy seasons and evaluates in which regions extreme rainy seasons are mostly affected by extreme precipitation events on a daily scale or by unusually large numbers of precipitation days.
