  • Mean properties of precipitation system

  • During 1998-2013, total 456684 snapshots of precipitation features with size > 80 km^2 have been collected over Atlantic_Ocean , where 1088 of them have lightning flashes inside. Some mean properties of these features are listed below:
    samples (#) mean size (km^2) mean volumetric rain (mm/hr*km^2) mean echo top (km) mean 30 dBZ ehco top (km)mean flash count (#)
    All 456684 211 809 3.8 1.3 0.01
    DJF 129757 233 946 4.0 1.4 0.01

    SON 79927 144 492 3.1 0.8 0.00

  • Extreme rainy events
  • In all 456684 precipitation features, top 1% ( volumetric rain > 11544 mm/hr*km^2) rainy features contribute 60 % of total rainfall. Top 100 rainiest events observed by TRMM during 1998-2013 over Atlantic_Ocean are listed here . Following figure shows the location of the precipitation feautres categorized by the volumetric rainfall.


  • Extreme intense events
  • Some of the precipitation sytems are much intense with large hails and many lightning than others (see the lists of top lightning storms. Following figure shows the location of the precipitation feautres categorized by the lightning rate and 30 dBZ echo top.
