  • Mean properties of precipitation system

  • During 1998-2013, total 858089 snapshots of precipitation features with size > 80 km^2 have been collected over Atlantic Ocean , where 501 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 858089 215 497 3.1 0.4 0.00
    DJF 148853 159 321 3.3 0.4 0.00
    MAM 268174 219 581 3.1 0.5 0.00
    JJA 261722 219 528 2.9 0.4 0.00
    SON 179340 247 476 3.1 0.3 0.00

  • Extreme rainy events
  • In all 858089 precipitation features, top 1% ( volumetric rain > 4788 mm/hr*km^2) rainy features contribute 75 % 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.
