VARIATIONS OF PRECIPITATION AND WATER RESOURCES IN THE NORTHERN PART OF VIETNAM UNDER CLIMATE CHANGE

抄録

With long coastline (3,200 km) and many large deltas, Vietnam is particularly susceptible with climate change. In the recent decade, Northern Vietnam has been facing terrible weather regime disturbances with increasing frequency and intensity of extreme weather events. As the earth temperature is projected growing higher, many scientists have indicated the warmer condition in the South-East Asia associated with increasing trend in precipitation; however, there is still a limited understanding about the future climate condition in Northern Vietnam. This study uses the observation climatological data and the updated dataset of 5th phase of Climate Model Intercomparison Project (CMIP5) to investigate the future variation in climate condition as well as water resources in the North of Vietnam. Despite of the decline in rainfall and the increase in evaporation during the recent decades, future rainfall and evapotranspiration are expected to increase. Thus, future water budget might increases, mostly in summer and autumn.
