  • Precipitation seasonal variation

    • Over TRMM region , mean annual precipitation are estimated with 975.7 (mm/year) from TRMM precipitation radar. (distribution of precipitation see here )

    Total surface rainfall is brought by various precipitation systems. The seasonal variation of precipitation from systems with different sizes and heights are shown below:

    In total, thunderstorms (systems with detected lightning flashes) contribute 28 %, MCSs (Mesoscale convective systems with raining area > 2000 km^2) contribute 74 % of all precipitation. Seasonal variations of fraction of precipitation from thunderstorms and MCSs are shown below:

  • Cloud seasonal variation

    • The seasonal variation of geographical distribution of CloudSat cloud fraction over TRMM region is shown below:





    The seasonal variation of mean CloudSat level cloud fraction at different altitudes over TRMM region is shown below:
