| Result from field campaign introduced. Horizontal and vertical patterns
of radar reflectivity factor from Precipitaion Radar(PR) agrees well with
ground-based radars or airborne radar. In addition, resu;ts of airborne
radar also agrees well with those of ground-based radars, though there
still are some discrepancies. Based on a confidence of the PR's performance, precipitataion system was analysed over Indian site for (May/June/August of 1998) rainy season. Vertidal profiles of radar reflectivity factor at Indian site were found to be associated with topography. Rain was spotty over PR swath. Shorter rain extent was found at Indian site as compared to Japan site. Stratiform precipitation was dominant at Japan site while convective found dominant at Indian castal region. Diurnal variarions precipitaion during June 1 - July 31, 1998 and September 1998 were investigated using Tropical Rainfall Measuring Mission (TRMM) PR data over 10S-40N, 60E-180at the intervals of four hours. We found a significant diurnal variation in land and near land ocean. Over the land areas, precipitations is seen more frequent in about 16-23 Local Time. And over near coastal oceans, precipitation is seen about 4-11 Local TIme. The rain distribution is nearly the same up to about 4-5 km hegiht, and has a same diurnal variations |
