Abstract
Through the comprehensive analysis of the high and low altitude situation, the ground situation and the numerical forecasting products, a middle - large snow and local blizzard weather process in Huludao from the evening of February 12th, 2009 to the morning of the next day was systematically analyzed by using the references of convention observation, mathematical forecast, satellite cloud picture and so on. The results showed that the beneficial coordination of high and low altitude and intersection of cold and warm air were the key factors of this synoptic process. It was the main reason of the early rain and late snowing that the earlier period was dominated by the warm and wet air, and the later period was controlled by the dry and cold air.关键词
