บทคัดย่อ

In this research, microphysics scheme is one main important scheme to simulate high-resolution rainfall and extreme rainfall event. It has impacted increase natural or relating to aerosols in the atmosphere. It can modify climate in the atmosphere because it can change precipitation efficiency. This research, two microphysics schemes (Lin scheme and WSM6 scheme) in the Weather Research and Forecasting (WRF) model were used to simulate three extreme rainfall events over Thailand with three nested domains. The innermost domain was 4 km ื 4 km and covered Thailand area. The results of extreme rainfall events given by the simulations from two microphysics schemes can be compared with the trend of rainfall spatial distribution from the TRMM data. The spatial pattern results of extreme rainfall events given by the two microphysics schemes. It can capture the trend of extreme spatial rainfall distribution with TRMM data. The statistical comparison was supported by the spatial pattern. It was shown the value less than 0 almost three cases that mean the results from the simulation were underestimate than TRMM data. However, the statistical comparison was shown a good trend from two microphysics scheme. In general, the trend of rainfall from two microphysics schemes of the WRF model good approximately extreme rainfall three cases with TRMM data over Thailand. ฉ 2018, Int. J. of GEOMATE.
