摘要
研究广西早春旱天气的前期大气环流及要素场的异常特征发现 ,冬季 5 0 0 h Pa高度场 ,月平均降水、温度 ,冬季海温、极涡强度指数 ,亚欧纬向环流等与广西早春旱关系密切。用建立的广西早春旱预报模型对 1
Investigated are the anomaly features of atmosphere circulation and meteorological elements prior to early spring drought in Guangxi.It is found that the drought is closely related with the geopotential height at 500 hPa,precipitation,temperature,SST,polor vortex intensity and Eurasian zonal circulation in the proceeding winter.A regression model is developed to predict the drought in 1998.
