| Outline of Final Research Achievements |
The precipitation characteristics were studied using the Tropical Rainfall Measuring Mission (TRMM) satellite data around Himalayas, Western Ghats mountain range, and west coast of Mynmar. Reanalysis data were used to identify the atmospheric conditions, particularly, water vapor transport in the lower atmosphere. The precipitation is characterized into two types: frequent but weak one and rather rare but strong one. Different characteristics appear depending on areas and seasons, which are understood to be caused by different atmospheric conditions. The precipitation characteristics over the tropical Western Pacific Ocean were also investigated using TRMM data along with geostationary meteorological satellite data. The precipitation systems were tracked using the cloud movements from the geostationary satellite data. The evolution of precipitation systems was clarified. The vertical structure of latent heat release was also obtained.
