Characterization of Extreme Rainfall Events Classes in the Tropical Andes by Using Weather Radar Data

Abstract:

Extreme rainfall is characterized by a high spatio-temporal variability. This variability is exacerbated in mountain areas, such as the tropical Andes, where the complex orography and mesoscale atmospheric processes have an enormous influence on the rainfall processes. Particularly the analysis of extreme rainfall events in the Ecuadorian Andes has remained a challenge due the lack of high spatio-temporal resolution operational observing systems. However, the recent availability of rainfall radar data in this area enables an improvement of our knowledge about those extremes. Here, we presented a study that aims to identify specific types of extreme rainfall events based on a clustering approach and to analyze their spatio-temporal characteristics. The study is based on three years of data collected from an X-band scanning weather radar that was located at 4450 m asl in the Tropical Andes of southern Ecuador …
