| Research Abstract |
Radar data composite map covering almost whole Indochina was constructed successfully from many radars in Thai, Lao and Vietnam. It was shown that the atmospheric environment was favorable for precipitation in cases of long? life typhoons passing over the Indochina. Regional numerical model simulation reproduced the typhoon center position very well, and, more over, caught the characteristics of internal structure of decaying typhoon in the Indochina as well as Doppler radar analysis of Lao radar data. It was also found that the precipitation from typhoons significantly increased in autumn in the eastern middle coast of the Indochina and was strongly affected by ENSO.
