摘要 锋前暖区暴雨是华南前汛期暴雨的主要特点,但暖区暴雨常常难以模拟和预报,给气象工作者带来挑战,因此对影响其发生发展的环流背景、天气系统、中尺度系统以及地形等进行深入研究,对提高暖区暴雨的预报能力有重大意义。近年来我国气象学者对华南暖区暴雨进行许多研究,本文主要对华南锋前暖区暴雨研究的天气系统及地形等进行简要概述,介绍了暖区暴雨发生时中高纬大气环流、副高、南亚高压和高空急流等大尺度环流背景,南海季风与华南暖区暴雨的密切联系,天气尺度系统以及中尺度系统在暖区暴雨中的重要作用,地形条件对暖区暴雨的影响。 During pre-fiood season in South China Torrential rain is mainly prefrontal warm sector heavy rain. But torrential rain in warm sector is difficult to simulating and forecasting, which brings challenge to meteorologists. Therefore, studying the circulation background, main weather systems, mesoscale convective systems and topography that affect the occurrence and development of torrential rain in warm sector in South China are significant to improve the forecasting capability of torrential rain in warm sector. In recent years, our meteorologists conducted a lot of research on torrential rain in warm sector in South China. A brief overview of the weather system and topography on torrential rain in warm sector in South China is summarized, such as the large-scale circulation background of the large-scale circulation in mid-high latitudes, the subtropical high, the South Asia high and the high altitude jet stream. It also introduces the close relationship of the South China sea monsoon and torrential rain in warm sector, and the important role of synoptic scale system, mesoscale system and topography.
