Warm-sector heavy rainfall (WSHR) events in China have been investigated for many years. Studies have investigated the synoptic weather conditions during WSHR formation, the categories and general features, the triggering mechanism, and structural features of mesoscale convective systems during these rainfall events. The main results of WSHR studies in recent years are summarized in this paper. However, WSHR caused by micro- to mesoscale systems often occurs abruptly and locally, making both numerical model predictions and objective forecasts difficult. Further research is needed in three areas: (1) The mechanisms controlling WSHR events need to be understood to clarify the specific effects of various factors and indicate the influences of these factors under different synoptic background circulations. This would enable an understanding of the mechanisms of formation, maintenance, and organization of the convections in WSHR events. (2) In addition to South China, WSHR events also occur during the concentrated summer precipitation in the Yangtze River-Huaihe River Valley and North China. A high spatial and temporal resolution dataset should be used to analyze the distribution and environmental conditions, and to further compare the differences and similarities of the triggering and maintenance mechanisms of WSHR events in different regions. (3) More studies of the mechanisms are required, as well as improvements to the model initial conditions and physical processes based on multi-source observations, especially the description of the triggering process and the microphysical parameterization. This will improve the numerical prediction of WSHR events.

摘 要

中国学者针对暖区暴雨的研究已有几十年的历史, 主要研究了暖区暴雨的形成环流背景条件、 分类、 以及中尺度对流系统触发机理和结构特征. 本文回顾了近年来暖区暴雨的主要研究成果. 暖区暴雨主要由中小尺度对流系统引发, 具有明显的突发性和局地性特征, 数值模式预报和客观预报的预报难度仍然很大. 今后需要在以下三个方面继续开展研究: (1) 深入了解我国暖区暴雨的形成机理, 揭示各种因子的具体影响, 并指出这些因子在不同天气背景环流下的不同影响. 这将有助于理解引发暖区暴雨的对流系统的形成、 维持和组织机制. (2) 除华南地区外, 江淮流域和华北地区夏季降水集中期间也有暖区暴雨过程发生. 应利用高时空分辨率的数据集分析我国不同地区暖区暴雨的分布和发生环境条件, 进一步比较不同地区暖区暴雨事件触发和维持机制的异同. (3) 除了机理研究, 还需要开展如何利用多源观测改进数值模式的初值和物理过程, 特别是触发过程的描述和微物理参数化过程, 这些研究将有利于提高暖区暴雨数值预报的准确率.
