Global warming and climate change in Chi-Mun river basin (Thai)

Abstract

This study of climate change in Chi-Mun river basin is a summary of future climate projection dataset, which is generated from PRESIS regional climate scenario using data from ECHAM4 A2 Global Circulation Model as initial data for simulation. Comparison of result from the regional climate model with data from observation at meteorological observation stations shows that the result from climate model still vary from observe data, therefore, rescaling technique was applied to the dataset in order to adjust the model bias.Final result of future climate projection from regional climate model, PRECIS, shows trend of rising in temperature in Chi-Mun basin, both maximum and minimum temperature. Moreover, the warm period over the year will also extend longer and cover wider coverage. Annual precipitation will increase in the future.
