Abstract: Based on days of glaze, rime and their mixture of 82 meteorological observation stations, and icing thickness of 15 ice observation stations with altitude information from station establishment time to February 2018 in Anhui Province, the standard icing thicknesses of 82 stations under 30, 50 and 100 years reoccurrence periods in Anhui Province were calculated by establishing the relationship between icing thickness and glaze days. Finally, the terrain data were used to correct the standard icing thickness. The results show that the standard icing thickness had a significant positive correlation with days of glaze, rime and their mixture, while it was exponentially related to the altitude under each recurrence period in Anhui. In the region where altitude is greater than 100 m, a more reasonable spatial distribution of standard icing thickness under each recurrence periods could be obtained by using terrain corrections.
Key words: standard icing thickness, recurrence period, terrain correction, Anhui Province
摘要: 利用安徽省82个气象观测站自建站至2018年2月雨凇、雾凇、混合淞日数,15个观冰站覆冰厚度和海拔高度数据,通过建立覆冰厚度与凇日数之间的关系,推算安徽省82个测站30 a、50 a和100 a一遇的标准冰厚,最后利用地形对标准冰厚进行订正。结果表明:安徽省各重现期下的标准冰厚与雨凇、雾凇和混合凇总日数具有显著的正相关关系;海拔高度与各重现期下标准冰厚呈指数关系;对海拔高于100 m的地区利用海拔高度对标准冰厚进行订正,可得到更为合理的安徽省各重现期下标准冰厚空间分布。
