Heavy Rainfall

There are many ways to define heavy rainfall events. Here we are presenting the events with the largest total rain volume in one precipitation system observed by TRMM during the past decade (1998-2007). These rainfall events do not necessarily have the heaviest instantaneous rainfall rate. But they have one thing in common: very large raining areas. Over tropical oceans, many such cases are found in tropical cyclones. Over tropical land, these raining events are more likely to be large Mesoscale Convective Systems (MCSs), especially over South America (see detail on google map).

Heavy rainfall events over different regions

Apparently, it is not fair to compare the rainfall from large MCSs over South America to the rainfall from warm rain systems over Hawaii. So it is important to know the relative frequency of large and/or heavy rainfall events for different regions. Current plan is to show the top 10 (or more) heavy rainfall cases for each 10x10 degree box globally. The result will come out soon...

Heavy rainfall events during different seasons

Current plan is to show the top 10 (or more) heavy rainfall cases for each 10x10 degree box globally for four different seasons (DJF, MAM, JJA, SON). The result will come out soon...
