摘　　要：近年来,一种发生速度较快、破坏程度较高、预报难度较大的新干旱类型--"骤发干旱"被提出之后,随着美国2012年特大干旱的爆发,骤发干旱的研究引起了美国社会的高度重视,我国及其他国家的有关研究也迅速展开。介绍了骤发干旱定义的认识及深化过程,由最初定义的热浪型骤发干旱扩展为热浪型骤发干旱与降水短缺型骤发干旱两种。从地面气象观测数据为主、实测与模拟土壤含水量为主、遥感分析与解译技术为主三个方面归纳了识别与监测骤发干旱的现有方法。总结了骤发干旱发生机理与时空变化特征方面的进展,对骤发干旱的研究前景进行了展望。In recent years,a new concept of drought called flash drought has occurred at a rapid rate with a high degree of damage and which is hard to predict.With the outbreak of an extremely severe drought in the United States in 2012,the study of flash drought has been paid remarkable attention in the US.The research on flash drought has begun rapidly in China and other countries.This paper introduced the connotation of flash drought and its deepening process,which was drawn-out from single heat wave flash drought to another precipitation deficit flash drought.The existing methods of identifying and monitoring of flash drought were summarized based on three sources,such as the ground meteorological data,the measured and simulated soil moisture,and the remote sensing analysis and interpretation techniques.Furthermore,the progress of the mechanism and spatiotemporal characteristics of flash drought were summarized and the research prospects of flash drought were proposed.
