Description
Summary:The icing environment is a major threat to aircraft flight safety and must be analyzed. In this work, the icing index is calculated using the interpolation method to process the sounding data of multiple stations in China. The results show that: 1) Before and after the summer rainfall process, there are obvious changes in the ice accretion index in the 4-6km height area of Northeast China, and the areas with serious ice accretion are basically coincident with the areas with large rainfall estimates. 2) In the process of snowfall in winter, the ground snow has an impact on the ice accumulation index in the east of China. When there is snow on the ground, the ice accumulation in low altitude is serious. The results of this study offer a theoretical basis for prediction and early warning of aircraft icing.
