Abstract
The surface wind speed is an important climate variable for study of ocean wave energy and coastal erosion. The wind speed and wave height variations are caused by global warming. In the future, climate change impacts on changes of direction and wind speed which affect on wave height and wave period. The global climate model (GCMs) were developed by various institutions so each GCM has different GCM output. Then, the aim of this study is to evaluation the performance of GCMs for wind speed analysis in the area of Gulf of Thailand and Andaman Sea. In this study, the daily wind speed data was analyzed with a total of 15 GCMs and daily wind speed data of NCEP-NCAR was used as observation data to compare with wind speed data from GCMs over the period 1986-2005 (20 years). Moreover, the wind speed data was evaluated by efficiency coefficient which are root mean square error (RMSE) and mean absolute error (MAE). It was found tht MRI-CGCM3, GFDL-ESM2M, IPSL-CM5A-LR, and IPSL-CM5A-MR are consistent with the most of observation data from NCEP-NCAR.
Highlights
Nowadays, the renewable energy are applied to solve the problem of reducing greenhouse gas emission
Fourteen weather stations of Thai Meteorological Department (TMD) in the area Gulf of Thailand (GOT) were used as locations of grid point in order to compare between observation and GCM
The results found that the root mean square error (RMSE) and mean absolute error (MAE) values were both high and low
Summary
The renewable energy are applied to solve the problem of reducing greenhouse gas emission. Wave energy, which is one of renewable energy, is interesting and less developed than other renewable energy. There are many researches that study the evaluation of global wave energy resources [1,2]. Asia and Australasia regions receive the largest quantity of wave energy. Central America and the Mediterranean Sea and Atlantic Archipelagos region receive the slightest quantity of wave energy due to their mid-latitude position. The total global wave energy potential is around 32 PWh/year [3] and the wave energy in Southeast Asian is around
