  • Precipitation diurnal variation

  • Many studies suggested that the diurnal variation of the precipitation is related to the life cycles of the precipitation systems, which is frequently driven by the surface sensible heating. Over SE_Ethiopia_Somalia, mean annual precipitation are estimated with 257.4 (mm/year) from precipitation radar. Detailed diurnal variation of the precipitation at high resolution can be accessed here (NOTE: it may take long time to generate for a large area). The diurnal variation of precipitation from systems with different sizes and heights are shown below:

    In total, thunderstorms (systems with detected lightning flashes) contribute 46 %, MCSs (Mesoscale convective systems with raining area > 2000 km^2) contribute 51 % of all precipitation over SE_Ethiopia_Somalia. Diurnal variations of fraction of precipitation from thunderstorms and MCSs over SE_Ethiopia_Somalia are shown below:

  • Cloud day vs. night differences

  • Certainly there is a strong diurnal variation of different types of clouds. Because CloudSat observes at 0130 and 1330 local time, here the daytime and night cloud fraction in different seasons are presented:
