华南地区春季极端降水与地形的关系及未来预估
Present and future of extreme precipitation during the spring season in South China
摘要
Abstract
This study investigated the characteristics and future changes of extreme precipitation in South China using convection-permitting downscaling simulations.A positive correlation was found between extreme precipitation and elevation,particularly at lower to moderate topographic heights.The relationship between extreme precipitation and temperature generally exhibited a hook-shaped pattern.Under a warmer climate,extreme precipitation was projected to increase more significantly at higher elevations.Regions experiencing increased extreme precipitation showed elevated levels of convective available potential energy(CAPE)and reduced convective inhibition(CIN),indicating a more unstable atmosphere conducive to severe weather.Further analysis revealed a strong association between future changes in extreme precipitation and factors such as topographic height and large-scale atmospheric conditions.The rate of extreme precipitation increase was found to be between one and two times the Clausius-Clapeyron scaling.关键词
