中文摘要: 针对1998年8月上、中旬清江流域的典型致洪暴雨过程,就雨洪关系、环流形势、中尺度系统等方面进行了剖析。结果表明,清江流域洪峰直接由致洪暴雨形成,而雨团总时次与暴雨过程累积面雨量紧密相关。致洪暴雨的产生与500hPa副热带高压位置,高、中、低各层中尺度环流系统及其配置和演变密切相关。
中文关键词: 致洪暴雨，面雨量，中尺度系统
Abstract:Analyses of some aspects,such as the relation between heavy rain and flood, the atmospheric circulation and the meso-scale system about the typical flood-causing heavy rain process in QingJiang Valley in the first and the second dekad of august in 1998 are made. The results show that, flood peaks in QingJiang Valley are formed straight from flood-causing heavy rain and the total times and frequencies of rain clusters are closely related to the accumulating area averaged rainfall of the heavy rain process. Generation of the flood causing heavy rain is closely related to the situation of the subtropical high over the west Pacific at 500hPa, and the meso scale systems and their dispositions and evolutions in upper, middle, and lower layers.
