摘　　要：利用邯郸市气象观测站1981—2008年的电线积冰观测数据资料，对邯郸市电线积冰的气候特征进行了统计分析，结果表明：电线积冰日数呈减少趋势；电线积冰均发生在采暖期内，其中1月份最多；邯郸电线积冰多为雾凇造成，具有重量轻、危害小的特点。产生电线积冰时需同时具备低温和充足水汽两个条件。邯郸发生电线积冰的高空环流形势分平直环流型、低涡型、两槽-脊型和阻塞高压型等4种类型。Based on the meteorological station observation data of wire icing from 1981 to 2008 in Handan, the climatic characteristics of wire icing were analyzed. The results show that： the days of wire icing have a decreasing trend ; the wire icing happens in the heating period, and the days of it are most in January; the wire icing mostly caused by rime, with characteristics of light weight and less harmful. The weather conditions of producing wire icing should be in low temperature and have enough vapour at the same time. The characteristics of upper air circulation situation have four patterns, such as plane circulation pattern, low vortex pattern, two troughs and one ridge pattern, and blocking high pattern.
