摘要本文研究了2008年1 - 2月中国南方一次持续20天的冰冻降水过程的天气形势、准静止锋、青藏高原东移云团、地面条件和大气层结过程之间的相互作用。结果表明，造成这次冰冻降水过程持续时间长的主要原因是西风带北方支阻塞高压系统和南支低压槽的稳定异常天气形势，使北方冷空气和南方暖湿空气交汇。2008年1 - 2月，青藏高原云团在经过华南地区时，经历了几次相似的云团传播过程，并向东传播，对局部地区产生了明显的影响。华南地区出现了一个罕见的东西向准静止锋系统。
Abstract This paper investigated the interactions between the synoptic patterns, quasi-stationary fronts, eastward-propagating cloud clusters from the Tibetan Plateau, surface conditions, and atmospheric stratification processes associated with a 20-day event of freezing precipitation over southern China from January to February 2008. It was found that the long duration of the freezing precipitation process was primarily caused by stationary and anomalous synoptic weather patterns such as a blocking high pressure system in the northern branch and a trough in the south branch of the westerlies, which resulted in the convergence of cold air from northern China and warm, moist air from the south. The cloud clusters over the Tibetan Plateau propagated eastward and showed noticeable impacts in the local areas when they moved over southern China during several similar cloud propagation processes from January to February 2008. An east–west-oriented quasi-stationary front system in southern China, which is rare d...
