| Summary: | This study used TRMM-PR data to examine seasonal changes in rainfall
characteristics over the Indochina Peninsula, with a focus on the diurnal
rainfall cycle. No distinct seasonal changes in the phases of diurnal
variations of rainfall were found, even though low-level wind fields changed
largely with the seasonal march. Regions with an afternoon maximum received
large amounts of rainfall during the pre-monsoon season, whereas regions with
a nocturnal or morning rainfall maximum received little rainfall during the
pre-monsoon season. This result suggests that the difference in diurnal
rainfall variations may be associated with the regional differences in
seasonal march of monsoon rainfall over and around the Indochina Peninsula,
through the different mechanism between evening and morning rainfalls. |
