  • Precipitation seasonal variation

  • Over WEST_ATLANTIC_ITCZ , mean annual precipitation are estimated with 1572.4 (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 9 %, MCSs (Mesoscale convective systems with raining area > 2000 km^2) contribute 70 % 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 WEST_ATLANTIC_ITCZ is shown below:

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