CLIMATE CHANGE AND INCREASED EXTREAM TYPHOON-RAINFALL IN CENTRAL COASTAL AREA OF VIET NAM

Abstract

Climate change can exacerbate extreme weather events both in intensity and frequency, thereby increasing the risk of natural disasters. This study evaluates the level of increased extreme typhoon-rainfall in the past and future based on climate change scenario. Consequently, it identifies the increased risk of natural disasters due to climate change. The research results show that recently, there has been an observed increase in the intensity and frequency of typhoon-rainfall at most stations in the Central Coast region, with an average increase of about 27%. In the future, with the RCP8.5 scenario, the likelihood of the largest one-day rainfall exceeding 100 mm/day is projected to increase in the early and mid-century periods throughout the Central Coast region, with a potential increase of up to 20%.
