Using the PRECIS - Regional climate model to develop climate change scenario in 21 st century for Vietnam

Currently, Vietnam Institute of Meteorology, Hydrology and Environment (IMHEN) runs PREICS (Providing Regional Climates for Impacts Studies) for climate change scenarios of 21st century. The domain chosen is large which includes Vietnam and adjacent regions with the resolution of 25x25 km. In this paper, we introduce climate change scenario for Vietnam under the B2 scenario. Results show that temperature would rise in all 21st century, faster in the second haft of century than those in the first one, faster in the remote areas than those in the coastal areas, and faster in the northern areas than those in the southern areas. Changes in rainfall are very complex, heterogeneous in different regions, heterogeneity in future periods. By the end of 21st century, rainfall would rise in most country from 0 to about 15%, especially in the North West and Central Highlands.
