摘要:
采用NCEP逐日0.5°×0.5°再分析资料对2008年1月发生在中国南方地区的暴雪过程进行诊断分析,通过对水汽分布、低空西南急流、切变线和垂直大气运动等气象要素分析表明:副热带高压异常偏北,低空西南急流活跃,为南方地区输送了充沛的水汽;中高纬度欧亚地区大气环流经向度偏大,冬季风偏强,导致冷空气势力较强;强冷空气与暖湿气流汇合,加上汇合带的强抬升作用,共同造成了此次南方地区的大范围降雪天气过程。
Abstract:
Based on the daily reanalysis data NCEP (0.5°×0.5°), a heavy snowstorm event on January 2008 in southern of China was diagnosed. The diagnostic study on water vapor, southwest low level-jet, shear line and vertical movement indicates that the subtropical anticyclone locates at higher latitude, which strengthens the southwest jet and brings abundant water vapor to Southern China. The winter monsoon from high latitude region is strong, which transport more cold air to the south. The convergence of strong cold air and warm wet air flow induces violent ascending motion, which leads to the blizzard in Southern China.
