| 摘 要： | 基于湖南省97个地面气象观测站（其中28个站有电线积冰观测业务）自建站至2008年的日气象观测资料,雪峰山、东山峰高山站的部分电线积冰观测资料,NCEP/NCAR再分析资料及地理信息资料,开展了气象要素、温度垂直结构、地理信息等环境因子对电线覆冰厚度的影响分析;利用逐步回归方法建立了电线覆冰厚度与环境因子的回归模型;在对回归模型进行统计检验的基础上,开展了自建模型与其他两种相关模型的比对分析。检验及比对结果表明,自建模型具有可用性。

| Abstract: | Based on the daily meteorological data from the 97 observation stations （28 with wire icing observation） in Hunan province from their establishment to 2008, part of the wire icing data from the stations at Xuefeng and Dongshan mountain, the NCEP/NCAR reanalysis data and geographic informa- tion data, the influence of such environmental factors as meteorological elements, vertical structure of temperature and the geographic information on the thickness of wire icing was analyzed. By using the stepwise regression method, a regression model between wire icing thickness and environmental factors was established. Based on the statistical testing of the regression model, comparisons between this model and other two related models were carried out. Results show that the new model is valid. |
