AB  - In this study, the Weather Research and
Forecasting (WRF) model and the Coupling model
between Weather Research and Forecasting with Regional
Oceanic Model Systems (WRFROMS) model simulated
rainfall over Thailand. The period time simulation was on
the month of rainfall seasonal in 2015 and 2016. A
sensitivity test was conducted to examine the performance
of two different single moment microphysics schemes
(Lin scheme and WSM6 scheme) for the rainfall
simulation. The simulations were compared with the
Tropical Rainfall Measure Mission (TRMM) grid data.
The domain resolution for simulation was 15×15 km and
covered the Thailand area. The results of rainfall
simulation from WRF and WRFROMS given by the two
microphysics schemes can be compared with the trend of
rainfall spatial distribution from the TRMM data. On the
spatial pattern, the WRF model both Lin scheme and
WSM6 scheme were shown overestimation rainfall than
observation data. On the other hand, the coupled model
WRFROMS both Lin scheme and WSM6 scheme
decreased rainfall closely TRMM observation than the
WRF model. The overall results of the WRFROMS with
the WSM6 scheme supported the lowest RMSE and MAE
value than another scenario. However, in this study, the
rainfall prediction cases were concluded the WRFROMS
coupled model that can be used to simulate rainfall and
SST over Thailand and gave a better performance that
only the WRF model.
