摘　　要：利用常规气象资料和AMDAR(Aircraft Meteorological Data Relay,航空器气象资料中继)飞机气象资料,对2012年1月5日和23日贵阳机场飞机报告的两次强积冰个例过程进行了客观诊断分析。结果表明:"1.5"和"1.23"强积冰个例是静止锋形势下导致的,逆温层维持时间长,逆温层顶、逆温厚度基本不变且逆温强度有所增强;饱和冷云维持且冷云含水量不断加大,为强积冰的发生提供了有利的温度和水汽条件。AMDAR资料对于探空资料是有力的补充,能显示大气层结随时间细微的变化,为积冰预警预报服务提供参考。Using the routine meteorological data and AMDAR aircraft meteorological data, the objective diagnostic analysis of two severe aircraft icing events happened on 5 and 23 January 2012 in Guiyang Airport is made. The results show that these two severe aircraft icing events were caused by a stationary front; an inversion layer maintained a long time; the inversion layer top and inversion thickness were essentially the same; temperature inversion strength was enhanced; saturated cold clouds maintained and cold cloud water content continued to increase; the low-level inversion layer and saturated wet layer supplied favorable temperature and moisture conditions for severe icing. AMDAR data is a strong complement to radiosonde data, which can reveal the subtle changes of atmospheric stratification over time and provide references for icing warning and forecast service.
