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。
Based on the meteorological data of conventional meteorological data and AMDAR (Aircraft Meteorological Data Relay) aircraft, two cases of intense ice accretion reported by Guiyang Airport on January 5 and January 23 were objectively diagnosed and analyzed . The results show that the strong ice accretions of “1.5 ” and “1.23 ” are caused by the static front. The inversion layer is maintained for a long time, and the thickness of the inversion layer is basically unchanged and the inversion temperature is Which is enhanced. The maintenance of saturated cold cloud and the continuous increase of cold cloud water content provide advantageous temperature and water vapor conditions for the occurrence of intense ice accretion. The AMDAR data is a powerful complement to the sounding data, which can show subtle changes in the atmospheric layer over time, providing a reference for early warning and forecasting of ice buildup.
