通过对2010年8月24日积冰过程的分析得出:这次积冰发生地点附近为垂直运动上升区,配合云中密集的冰水混合物,是造成这次飞机严重积冰的主要原因.积冰指数对于积冰强度和区域的预报具有指示意义.WRF 中尺度数值模式选用 Eta Ferrier 微物理方案的模式结果中的云冰、云水以及总凝结混合比,这对于积冰强度和范围有一定的预报能力.

The analysis of the process of aircraft icing on August 24, 2010 shows that the icing oc-curs in the vicinity of the vertical current area with strong up draft. Clouds with dense ice water mixture cause the main reason for severe icing. Ice index for prediction of the intensity of icing and areas of icing has indicating significance. In WRF mesoscale model, Eta Ferrier micro-physics scheme is adopted to analyze the mixture ratio of ice and clouds, water and clouds and total condensation. The result of the analysis through the model proves certain prediction accuracy to the intensity and scope of icing.
