This research aims to study moisture transport over the Indian Ocean and South China Sea during the rainy season of Thailand in the years 2010 and 2011. The data is taken from the National Oceanic and Atmospheric Administration (NOAA) and the Global Precipitation Climatology Project (GPCP). The total vertically integrated moisture flux divergence, horizontal fluxes, and meridional fluxes are computed in this study. The results are vertically integrated moisture fluxes which perform from the surface to 300hPa. The main moisture transport occurs from west to east of the study area with strong wind components toward India and Thailand from the Indian Ocean. Furthermore, a deeper, vertically integrated moisture convergence in the year 2011 progressively appeared over Southeast Asia compared to the year 2010. A deeper convergence occurred in strong moisture over Thailand, which caused more rainfall in Thailand during the rainy season of the year 2011.
