2024年2月晋城雨凇天气过程与电线积冰形成条件分析

Analysis of the February 2024 Rime Weather Event in Jincheng and the Conditions for Ice Accumulation on Power Lines

摘要: 电线积冰是冬季常见的气象灾害之一，也是影响电网建设及其安全运行最大的隐患之一。进行电线积冰的气候特征及气象条件研究，可为电力气象服务开展提供技术支持，对电力部门输电线路安全运行具有重要的意义。本文通过分析晋城市2024年2月一次雨凇天气过程，对照国家站电线积冰观测数据，得出雨凇天气过程极大概率导致电线积冰。通过分析物理量场及探空条件，为之后分析雨凇天气过程、更好地开展电力气象服务提供参考。

Abstract: Ice accretion on power lines is one of the common meteorological hazards in winter and also one of the biggest hidden dangers affecting power grid construction and safe operation. Studying the climatic characteristics and meteorological conditions of ice accretion on power lines can provide technical support for power meteorological services and is of great significance for the safe operation of transmission lines by power departments. This paper analyzes an ice rain weather event in Jincheng City in February 2024, and by comparing it with national station observations of ice accretion on power lines, it concludes that ice rain events have a very high probability of causing ice accretion on power lines. By analyzing the physical field and sounding conditions, it provides a reference for further analysis of ice rain events and better implementation of power meteorological services.
