Abstract

Wire icing data at Baoji, Huashan, Luochuan, Wuqi and Yulin in Shaanxi observatories from 1980 to 2005 are analyzed to study the characteristics. When glaze and rime happen at the same time, it is taken as glime. Analyzing results shows Huashan has the most icing days annually, 40.3 days on average, while other observatories have 0.5 to 4.2 icing days on average. In Shaanxi, glaze is the most, rime is the second and glime is the least, taking the ratio of 55.2%, 27.9% and 16.9%, respectively. The icing days mainly concentrate from November to March. Huashan has the most icing days in March. Baoji and Wuqi have the most icing days in December. Luochuan and Yulin have the most icing days in January. The average equivalent diameters of glaze, rime and glime of Shaanxi are between 10 to 25 mm. The maximum equivalent diameter is 78 mm. The average masses are between 86 to 236g·m^-3. The average densities are among 0.22 to 0.34 g·cm³, with glime being the biggest, rime the smallest. The meridional average equivalent diameters, average masses and ave rage densities of are bigger than those zonal ones. The maximum mass of Baoji, Huashan, Luochuan, Wuqi and Yulin are 13, 1290, 94, 25 g·m^-1 and 25 g·m^-1, respectively.
