Abstract :
We examine the spatial and temporal distribution of the diurnal cycles derived from seasonal averages of 1° latitude by 1° longitude grids based on measurements of the TRMM Precipitation Radar. Afternoon maxima are found overland and nocturnal to early morning maxima are observed over the oceans. Regions of land-sea breeze are also delineated. The diurnal amplitudes are comparable to if not larger than the daily means
