To Understand Typhoons’ Behavior over Indochina

To understand the behavior of typhoons after their landing on the Indochina, radars operated by national meteorological services of countries in Indochina and numerical model. Radar echo intensity data from many radars in Thai, Lao and Vietnam were composed covering almost whole 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.
