中文摘要: 应用直径26.8和4 mm两种导线平行观测的电线积冰资料，对比分析两种观测资料中电线积冰直径、厚度、重量和标准厚度的差异，并对不同天气现象和气象条件下两种电线积冰观测资料的差异进行了讨论。结果表明：总体上, 2011年1—5月全国大部分台站观测的两种导线电线积冰直径、厚度和标准厚度值差异不明显，重量差异较明显，且差值较大的站点主要分布在长江以南地区；分析不同天气现象和气象条件下两种观测资料的差异后发现，两种电线积冰直径和厚度值差异在雾凇和混合凇条件下较显著，而重量值差异在雨凇、风力0~3级和气温-5~0℃的条件下时相对最大。

Abstract:An intercomparison of two kinds of wire icing observed data in China is performed to analyze the differences in diameter, thickness, weight, standard thickness of the wire ice in this study. The difference in the two icing observations under different weather phenomena and meteorological conditions is also discussed. The results show that the two kinds of wire ice (north south and east west) diameter, thickness and standard thickness data, which were collected by majority of the stations in the country from January to May 2011, have no significant difference. However, the difference in weight between the two datasets is obvious, especially in the areas to the south of the Yangtze River. Further analysis shows that the differences in ice thickness and diameter between the two datasets under the rime and mixed icing conditions are more significant, while the difference in ice weight reaches the maximum when the wind force is from Grade 0 to 3, the temperature ranges between -5℃ and 0℃, and the glaze occurs.
