Correlation analysis between glaze and atmospheric circulation as well as sea surface temperature in Hu′nan province
摘要
Abstract
Glaze is one of the major meteorological disasters in winter of Hu′nan province.The correlations between glaze and atmospheric circulation as well as sea surface temperature were analyzed in Hu′nan province.The results indicated that the polar vortex area over Asia and the location of East Asian trough play an important role to glaze weather in Hu′nan province.It is favorable to the formation of glaze in Hu′nan province when Eurasian zonal circulation index is low.Glaze weather often happens in Hu′nan province when the area index of East Atlantic blocking high over European is low and that of the Ural blocking anticyclone is high.It is not favorable to the development of galze in Hu′nan province if the area of western Pacific subtropical high becomes large and its intensity is strong,and the western normal position leans to west in winter.Glaze in Hu′nan province is most serious in the year that La Nina event ends and at the same time El Nino event begins.On the contrary,it is not serious in the starting year of El Nino event.关键词
