1980~2016년 기간 동안 베트남 Gia Lai 지역의 가뭄 현상에 관한 기후변화 연구

A Study on the Climate Change of Drought Phenomenon in the Gia Lai Province, Vietnam, during the Period from 1980 to 2016

Drought is a common and frequent type of natural disaster in Vietnam. This paper examines the yearly and seasonal variation of drought phenomena based on the two term indexes selected as the standardized precipitation index (SPI) and the evaporation / rainfall ratio index (K). Both drought indices have shown a good similarity in describing drought conditions in the study area. The results show that the years with long-term and high intensity drought in Gia Lai province are: 1981—1983, 1989, 1992—1994, 1997, 2004, 2006, 2014, and 2015. This research result is the basis for the make forecasts and early warnings about future droughts and develop timely and effective adaptation solutions. The manifestations of climate change are very transparent in Gia Lai province, expressed through the manifestations: the temperature tends to increase, the water source depleted, the increase in both frequency and intensity of weather phenomenon, extreme climate. Therefore, in Korea, the standard precipitation index (SPI) and the evaporation / rainfall ratio index (K) are required for prediction and comparison of drought occurrence.
