Abstract:

Significant advances in the formation mechanism and forecasting methods of severe convective winds and related convective systems were reviewed to improve understanding of the formation mechanism and forecast accuracy of severe convective winds. First, the spatial and temporal distribution characteristics of severe convective winds worldwide are briefly described. Next, the relationship between the organizational types and structural features of the parent convective systems that generate severe convective winds is then summarized, as well as the impact of atmospheric environmental conditions and topography, and forecasting methods. Finally, the current issues and future research directions associated with severe convective winds are discussed.

Key words: Severe convective wind, Organizational mode, Atmospheric environmental condition, Prediction method

摘要:

雷暴大风是预报难度较大的强对流天气之一,为了提高对雷暴大风形成机理的认识和预报准确率,对国内外雷暴大风和相关对流系统的形成机理与预报方法的重要成果进行了回顾。简要介绍了世界上雷暴大风的时空分布特征,中国的雷暴大风主要发生在东部地区,华北北部、东北中南部和广东为高发区。概述了产生雷暴大风的母对流系统的组织类型、结构特征以及雷暴大风的形成机制:飑线和弓状回波是产生雷暴大风的主要对流系统之一,且容易产生强雷暴大风;飑线或者弓状回波中的后向入流、γ-中尺度涡旋等系统是产生地面大风的重要结构特征。总结了雷暴大风发生的大气环境条件和预报方法:大气环境的有关热力和动力因子都会影响雷暴大风的产生和强度,但对流活动的强度主要依赖于对流有效位能和垂直风切变的共变关系;数值预报、基于物理理解的方法(配料法)和深度学习/机器学习方法是目前在雷暴大风的短临、短期预报业务中采用的主要方法。最后指出针对我国雷暴大风,在精细的时空分布特征、不同大气环境条件下形成机理和预报方法等方面仍有待进一步研究。
