青藏高原对极端天气气候影响:回顾与展望OA

Under the background of global warming,warming over the Tibetan Plateau has accelerated,with pronounced changes in the frequency and intensity of extreme high-temperature events,extreme precipitation events,and their compound occurrences.Through thermal anomalies,snow-albedo feedback,high potential vorticity systems,and teleconnection processes,the Tibetan Plateau exerts profound influences on extreme weather and climate over eastern China,South Asia,and the mid-to high-latitude regions of Eurasia.This paper systematically reviews research progress over the past decade(particularly the last five years)on the characteristics of extreme weather and climate changes over the Tibetan Plateau and the mechanisms by which they affect surrounding and downstream regions.Emphasis is placed on the evolution of extreme temperature and precipitation,the climatic effects of plateau snow cover and sensible heat heating,the triggering role of plateau high potential vorticity systems on downstream extreme events,as well as the"bridge"role of the Tibetan Plateau in interactions across different latitudes.On this basis,the major scientific issues and limitations in current research are discussed,and future research directions are outlined.This review aims to provide reference for deepening the understanding of Tibetan Plateau climate dynamics,improving the prediction of extreme weather and climate,and supporting disaster risk reduction and ecological security.
