摘要:

利用华家岭气象站不同高度、不同方向、不同导线直径的电线积冰观测资料,分析了电线积冰在不同高度、不同方向、不同导线的变化特征,以及与气温、水汽压、风速等气象要素的关系。分析表明,电线积冰量随高度增加而增加,随电线直径增大而增大;在相同高度、相同导线上,不同方向的积冰量与风向有关。电线积冰量与水汽压、风速分别呈正相关和反相关。在一定阈值内,电线积冰量和气温存在较好的相关性。

Abstract:

Wire icing is a serious meteorological disaster,which has attracted increasing public attentions since 2008. In this paper,
the variations of wire icing for different heights,directions and wire diameter were analyzed by employing the observational data of wire
icing at the weather station of Huajialing in Gansu Province from October 2007 to January 2008,when snow rainfall disaster occurred in
South - China. Combined the meteorological data,the relationship between wire icing and some meteorological elements,such as tem-
perature,vapor pressure and wind speed,was established. The results show that the amount of wire icing increased with the heights
and diameters of the wire. As for the wire at a given height,it was related to the wind directions. In addition,the amount of wire icing
showed a positive correlation with vapor pressure,and a negative correlation for wind velocity. In a certain threshold,there was a good
correlation between icing and temperature.

Key words: wireicing, weatherconditions, glazerime
