Based on MICAPS (Meteorological Information Combine Analysis and Process System) and observational data in Anshan Observatory, the freezing rain event occurred rarely in Anshan on February 24 in 2010 was analyzed. The results showed that there existed the inversion layer from the ground to 850 hpa level even to 700 hPa level when the local surface temperature was below 0 ℃. The temperature stratification structure of coldness-warmth-coldness was prevailing from the upper level to the ground with the existence of the ice melting layer of a certain thickness. Thus the freezing event occurred in Anshan.%利用MICAPS和鞍山站实况资料,对2010年2月24日鞍山出现的罕见冻雨天气进行分析.结果表明,当地面气温在O℃以下,地面到850 hPa甚至到700 hPa有逆温层,从高空到地面为冷-暖-冷的温度层结结构,且存在一定厚度的冰晶融化层时,鞍山市出现冻雨天气.
