摘　　要：该文利用１５年资料，分析了北京降雪的天气气候特点．主要结果是∶降雪年际变率大；１１月、２月和３月雪量大；降雪的环流型主要有低槽（涡）型和中亚低槽东亚高后型两类；充沛的水汽和能量是北京降雪的必要条件．Based on the data of snowfall from 1980 to 1994, the climatic characteristics of snowfall in Beijing area are investigated. The results show that the interannual variability of snowfall is quite large, and the amount of snowfall in November,February and March are larger. Furthermore, there are two kinds of circulation patterns: trough(vortex) pattern, and trough of mid Siberia and ridge back of east Siberia pattern. Sufficient moisture and energy are the necessary conditions for snowfall in Beijing area.
