Study on the Characteristics and Its Previous Affecting Factors of Winter Cold Air Activities in China
Abstract: Based on the observations of cold-air mass activity, air temperature records over nationwide of 160 stations, sea Surface pressure fields of north hemisphere, and the height fields at 500 hPa, as well as the related circulation indexes of the winter periods during 1951 to 2010, using the methods, such as composite analysis, differential analysis and correlation analysis, the possible links between cold-air activities and the other above data series are studied. The results show that the winter air temperatures in our country are closely related to the cold air activities. In addition, some atmospheric circulation indexes are found out, which are good indicators for winter cold air activities, and can be used as tools for forecasting winter cold air activities.
