Abstract
A coupled regional climate between atmosphere-ocean coupled model systems is developed using the regional model Weather Research and Forecasting (WRF) and Regional Ocean Modeling System (ROMS) to simulate performance rainfall during the rainy season over Thailand. The processes of the atmospheric model are provided to the ocean model. The wind (Uwind, Vwind), the atmospheric pressure (Patm), the relative humidity (RH), the atmosphere surface temperature (Tair), the cloud fraction (Cloud), precipitation (Rain), the short wave (SW), the long wave (LW). The processes of the oceanic model provide sea surface temperature (SST) to atmosphere model. The simulation period is during June-July-August (JJA) in 2014, and the results are compared with rainfall gauge station from Thai Metrology Department (TMD). The results show a good trend performance rainfall and can capture large amount rainfall in June, July and JJA 2014. The average rainfall and Mean Absolute Error (MAE) showed good value in June, July and JJA 2014, especially in June was shown good value average (236.25 mm) and MAE (4.389) than other months. ฉ Int.
