Climatology and Case Studies of Extreme Precipitation Events From TRMM Observations

Extreme precipitation events based on volumetric rain rate is quite different from those based on the intensity of convection. This study utilizes the precipitation feature data set developed at the University of Utah to analyze those extreme precipitation events that brought the largest amount of rainfall in any given location and any given time. We will present the geophysical distributions of such defined extreme precipitation events and their diurnal, seasonal and interannual variations. Characteristics of these extreme precipitation events and their dynamic and thermodynamic environment will be examined through composite analysis and case studies. In particular, we will show a case study on a large-scale precipitation system occurred during June 16 and 21, 2010 in the southern China that caused devastating floods in the region.
