Hi oaikin: Thanks for the interesting question. Yes, it is true that in the tropics, rain occurs more often in the early afternoon than in the morning. However, one proviso to that is that this only holds true for continental areas of the tropics - over the tropical oceans, rain tends to fall overnight and into early morning. TRMM Application on Tropical Rainfall Diurnal Cycle URL: http://daac.gsfc.nasa.gov/precipitation/trmm_apps/trmm_diurnal.shtml Quote: "Diurnal cycle of precipitation over the global tropics derived from the TRMM Combined Instrument algorithm (2B31). The pixel data are binned into geographic local time 3 hourly 1x1 degree boxes. There is a nocturnal to early morning maximum over the oceanic rain belts. Rainfall maximum over the continents occurs in early afternoon. The drastic shift of the maximum rainfall over the Maritime Continent from early morning in the coast to late afternoon in land suggests a strong coupling in land-air-sea interactions." Note: Have a look at the interesting plots!
