| 摘 要： | 利用常规气象资料和NCEP再分析资料，对2008年1月安徽一次暴雪天气的分析发现，一方面中高纬度欧亚大陆大气环流出现异常，冷空气活动频繁并不断南下；另一方面副高异常偏北，长江中下游地区中低空盛行西南暖湿气流，冷暖空气不断交汇，形成了连续的低温降雪天气。中低层低涡切变是主要的影响系统，冷平流持续使近地面层气温降至0 ℃以下，有利于降雪的形成和维持，从而造成严重冰雪灾害。

| Abstract: | Based on conventional meteorological data and NCEP reanalysis data,the snowstorm process in January of 2008 in Anhui was diagnostic analyzed.The results showed that the atmospheric circulation background in the mid-high latitude of Eurasia occurred abnormal status.Thus,the clod air could be successively transported to Anhui Province.Another,the western Pacific subtropical high was abnormally located more northward and the successive transportation of southwest warm moisture air flows were located in the mid... |
