摘要
对多年导线覆冰灾害资料及现场导线覆冰测量调查资料进行分析。结果表明,广西导线覆冰主要是雨凇与雾凇的混合冻结;纬度越高、海拔越高,覆冰越严重;迎风面比背风面严重;靠近水库、河流等水体地区覆冰程度明显加重。中路、东路冷空气南下容易产生导线覆冰现象;寒潮暴发南下,地面静止锋在华南沿海维持,西南暖湿气流不断向华南上空输送,对流层中低层有逆温层,此时导线易出现覆冰。地形对导线覆冰的出现有较重要作用。
The analysis of the data showed that conductor icing is mostly mixed freezing of glaze and rime in Guangxi,it becomes more severely with the latitude moving northward and the increasing of altitude,and it is thicker on the leeward side and in the water around than that on the windward side and in other place by using the data sets of the many years ice-coating disaster and field investigation.The middle and eastern cold atmospheres which pass through from the north can more easily affect the ice-coating.When the cold wave is outbreak and the stationary front on surface is staying in the Coast of South China,it is more easily to occur conductor icing,associating with the warm and moist water vapor which transfers continuously to the South China and the inversion layer in the mid and low troposphere.Landform makes an important contribution to the ice-coating of Guangxi.
