分析了2009年11月9日北京地区对流性降雪天气过程,冷锋是这次对流性降雪天气的天气尺度影响系统.干冷空气补充使锋面扰动增强,同时扰动上传使得中层不稳定能量释放,进而使得中尺度对流系统得到维持和发展,最终导致这次暴雪天气的出现.
分析瞭2009年11月9日北京地區對流性降雪天氣過程,冷鋒是這次對流性降雪天氣的天氣呎度影響繫統.榦冷空氣補充使鋒麵擾動增彊,同時擾動上傳使得中層不穩定能量釋放,進而使得中呎度對流繫統得到維持和髮展,最終導緻這次暴雪天氣的齣現.

This paper analyzes the November 9, 2009, Beijing area convection sex snowfall weather process, cold front is the convectional snowfall weather weather scale influence system. Dry cold air supplement to frontal disturbance increase, and at the same time disturbance upload make middle unstable energy release, and then makes the mesoscale convective system for the maintenance and development, and ultimately lead to the emergence of the blizzard weather.
