西南地区严重飞机积冰环流分型研究

Research on Classification of Circulation Patterns for Severe Aircraft Icing in Southwest China

摘要: 本文基于2015~2020年西南地区话音式航空器空中积冰报告资料和ERA5再分析资料，按照较为严重飞机积冰报告为标准，对造成严重飞机积冰的环流背景分为冷空气切变线/低涡型、冷空气型、切变线/低涡型和高空槽型共4个类型，为西南地区飞机积冰预报业务及管制人员更有效地指挥飞机避开可能存在的积冰区提供便利。

Abstract: Based on voice-based aircraft icing reports and ERA5 reanalysis data in Southwest China from 2015 to 2020, this study classifies the circulation backgrounds associated with severe aircraft icing into four types: cold air shear line/low vortex type, cold air type, shear line/low vortex type, and upper-level trough type. This classification aims to facilitate aircraft icing forecasting operations and assist air traffic controllers in more effectively guiding aircraft to avoid potential icing zones in Southwest China.
