利用卫星资料识别潜在飞机积冰区

摘要

针对天气学方法预报飞机积冰实际效果准确率低并受具体时空范围的束缚等问题，结合卫星资料在民航的广泛使用，设计了利用卫星提供的云微物理参数识别潜在飞机积冰区的算法，从而得到较大区域范围的潜在积冰概率和积冰强度。并用实际飞机积冰案例进行验证分析，发现利用卫星资料识别潜在飞机积冰区的积冰概率和积冰强度与飞机实测结果一致，表明利用卫星资料提供的云微物理参数的积冰算法能够有效识别潜在飞机积冰区。%Aiming at the existing aircraft icing detection and forecast mainly depend on synoptic method and the results,the accuracy is low and bounded by specific scope of space and time.Combined with the using of satellite data,this paper puts forward a recognition algorithm of potential aircraft icing area using cloud micro physical parameters provided by satellite data in order to get icing probability and icing intensity of the large area.By analyzing the actual aircraft icing case,the icing probability and inten-sity of icing area recognized by satellite data are consistent with the plane observation.The results show that icing algorithm of cloud microphysical parameters provided by satellite can effectively identify po-tential aircraft icing area.
