2015年11月湘江流域罕见的冬季暴雨天气过程分析
Analysis of the Rare Rainstorm Weather Process in Xiangjiang Basin in 2015
摘要
Abstract
Based on the national centers for environmental prediction global forecast system reanalysis data,weather station data and Doppler radar data,we have analyzed a heavy rain event that occurred in Hun'an in 10-12 November 2015.The results show that it was the largest flood in Xiangjiang basin since 1961.After the ridge line was strengthened in Ural,the low move to the east in the Bay of Bengal,the western Pacific subtropical high strength is stronger,the ridge line is maintained at 20°N,the cold high in the near surface area in East China and the warm low moving to northeast confrontation in South Hu'Nan,the heavy rain occurred in the advantageous circulation background,it occurred in addition to steady atmospheric stratification.The southwest moist air from the Bay of Bengal meets the cold air from the north,dynamic condition was provided by sustainable convergence and updraft,due to the heavy rain event.关键词
