大气对流初生的研究进展与展望

Research progress and prospect of atmospheric convection initiation

大气中的对流初生(Convective Initiation,CI)是强对流天气发生的重要征兆,是强对流天气预报预警的重点所在,近些年越来越被关注。本文回顾了国内外CI的研究进展,主要包括CI的定义、基于雷达数据和卫星数据的CI成熟算法、CI局地时空分布特征、影响CI的主要因子等方面。在此基础上,对CI未来研究作一展望,以期加深对CI的认识,为强对流天气短临预报预警提供参考依据。

Convective initiation(CI)in the atmosphere is an important symptom of severe convective weather and the focus of severe convective weather forecast and early warning,which has been paid more and more attention in recent years.This paper reviews the research progress of CI at home and abroad,mainly including the definition of CI,mature CI algorithm based on radar data and satellite data,local space-time distribution characteristics of CI,and main factors affecting CI.On this basis,the future research of CI is prospected in order to deepen the understanding of CI and provide reference for the short-term and imminent forecast and early warning of severe convective weather.
