Variations in the middle and upper atmospheric environment and their im-pacts on weather and climate disasters:introduction to major project and latest progress
摘要
Abstract
The middle-upper atmosphere has been identified as a frontier scientific research area in the World Weather and Climate Research Program due to its significant impact on tropospheric weather and climate.Moreo-ver,as a transitional space from aviation to space,it has been regarded as the new"high frontier"for national de-fense security.In China,due to insufficient observational data and a lack of comprehensive middle-upper atmos-pheric models,our understanding of variations in the middle-upper atmospheric environment and their weather/climate disaster effects is not sufficiently profound.To deepen our understanding of the mid-to-upper at-mosphere,the major project"Variations in the middle and upper atmospheric environment and their impacts on weather and climate disasters"was granted by the National Natural Science Foundation of China.This project aims to conduct the following research:1)Develop new technologies and methods for observing the composition of the middle-upper atmosphere,carry out integrated"sky-to-ground"multi-element collaborative observations,and obtain multi-temporal and multi-spatial scale observations of the middle-upper atmosphere.2)Study the impact of cross-atmospheric layer interactions and multi-source disturbances on the middle-upper atmosphere,quantify the influences and contributions of external forcing factors and internal variability on the variations in the middle-upper atmosphere.3)Improve the physical and chemical processes of the middle-upper atmosphere in the model,and establish a data assimilation system for the middle-upper atmosphere.4)Investigate the impacts and mechanisms of variations in the middle-upper atmosphere on extreme weather and climate,particularly in East A-sia,assess their disaster effects and risks.The expected results will provide new insights for extreme weather fore-casting and early warning,and offering important technological support and decision-making basis for disaster prevention,mitigation,climate change response,and even national defense security.This article briefly introduces the research background,content,and key scientific issues of the project as well as recent main achievements of this project.关键词
