We can derive some information on diurnal cycle of the precipitation from long-term statistics of the TRMM data.
Distribution of the ratio of precipitation amount
in the afternoon to morning in 1998 and 1999.
Distribution of the ratio of afternoon rainfall (from 12:00 to 18:00 local time) to morning rainfall (from 06:00 to 12:00 local time) calculated by using PR rain rates from 1998 to 1999. Blue indicates the dominance of precipitation in the morning, and red in the afternoon.
