| description | A cold wave is a hazardous event experienced in the middle latitudes during the winter that significantly influences civil aviation. This study utilized the fifth-generation ECMWF reanalysis (ERA5) data and aerodrome routine meteorological reports (METARs) from 36 airports in China to analyze the impacts of a cold-wave event from November 26 to 30, 2022. We assessed the effects on wind, visibility, thunderstorms, precipitation, ground-icing conditions, in-flight aircraft icing conditions, and clear air turbulence. The results indicated that regions affected by the cold wave shifted from northwest to southeast, with notable impacts on wind, precipitation, and icing conditions. Strong winds, particularly crosswinds, affected airports in coastal regions and narrow valleys, enhancing wind speeds and creating hazardous conditions. Ground-icing conditions were prevalent, with 23 out of 36 airports experiencing significant icing, notably in Northeast, Central, southern, and eastern China. In-flight icing conditions were identified in the lower and middle troposphere, primarily affecting Northwest, Northeast, and Central China and the middle and lower reaches of the Yangtze River. At cruising levels, the cold wave introduced light clear air turbulence. This study provides valuable insights for improving civil aviation operations during cold-wave events, emphasizing the need for preventive measures and early warning systems to mitigate potential risks. |
