鄂州花湖机场一次典型辐射雾天气分析

A Typical Radiation Fog Weather Analysis of Ezhou Huahu Airport

摘要: 本文基于鄂州花湖机场自动观测系统资料及常规地面观测资料和高空资料，通过分析得知：本次辐射雾形成过程中，本场高空为偏北气流，晴空辐射带来辐射降温使水汽凝结，逆温层、地面风速较小有利于雾的维持，前期降水为大雾提供了充足的水汽条件，大雾开始于02:47，到09:44结束，此时能见度、跑道视程达到标准，属于一次典型的辐射雾过程。

Abstract: Based on the automatic observation system data of Ezhou Huahu Airport, conventional ground ob-servation data and high altitude data, this paper finds that: during the formation of the radiation fog, there was a northerly airflow in the upper air, and the clear air radiation brought about radiation cooling and condensation of water vapor. The low-temperature inversion layer and the wind speed on the ground were conducive to the maintenance of fog. The precipitation in the early stage provided adequate water vapor conditions for the fog. The fog began at 02:47 and ended at 09:44, when the visibility and runway visual range reached the standard, which was a typical radiation fog process.
