Weather System Analysis of Storm during Flood Peaks in Upper Reaches of Three Gorges Reservoir
摘要
Abstract
Selecting the inflow in Three Gorges Reservoir as the intensity of the flood, the main source of Yichang flood is the upper Yangtze River, including Min River, Jialing River, Wujiang River, Yibin-Chongqing River, Chongqing-Wanxian River, Wanxian-Yichang River. The authors choose the three major historical flood peaks in 1981, 1998 and 2010 as an entry point for the large peak storm process analysis. Using the surface rainfall,Yichang flow and water level of the six rivers in the upper Yangtze River and NCEP objective analysis, by the methods of weather analysis and spectral analysis, authors analyzed the main weather systems in lower troposphere,as well as the 200 hPa South Asian high and the ground cold air. The circulation characteristics of the three major historical flood peaks, wind field characteristics, super long wave and long wave characteristics are given. All these provide the weather background of flood peak storm for meteorological services to the Three Gorges Reservoir.关键词
