  • Mean properties of precipitation system

  • During 1998-2013, total 143161 snapshots of precipitation features with size > 80 km^2 have been collected over PERU_COAST , where 3573 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 143161 154 316 7.1 1.4 0.07
    DJF 56558 174 352 7.2 1.4 0.08

  • Extreme rainy events
  • In all 143161 precipitation features, top 1% ( volumetric rain > 4988 mm/hr*km^2) rainy features contribute 39 % of total rainfall. Top 100 rainiest events observed by TRMM during 1998-2013 over PERU_COAST 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.
