摘要
分析了南岳雨凇与冷冬及西太平洋副热带高压的关系。结果表明,在冷冬年份,南岳雨凇日数偏多;在暖冬年份,南岳雨凇日数偏少。西太平洋副热带高压与南岳冬季气温密切相关。副热带高压偏弱时,南岳冬季偏冷;副热带高压偏强时,南岳冬季偏暖。副热带高压的588线北界偏北时,南岳冬季偏暖,反之偏冷。副热带高压的西伸脊点偏东时,南岳雨凇日数偏多,反之偏少,而且西太平洋副热带高压的变化超前于冷暖冬的变化。
The relationship among glaze in Nanyue Mountain, winter temperature, the subtropical high over the West Pacific Ocean is analyzed. The result shows that the number of glaze days in Nanyue Mountain is greater in cold winter and smaller in warm winters. The relationship between the subtropical high in the West Pacific Ocean and the winter temperature in Nanyue Mountain is quite evident. The winter in Nanyue is colder while the subtropical high is stronger, and vice versa. When the north boundary of the line 588 of the subtropical high deflects to the north, the winter in Nanyue becomes warmer, and vice versa. When the west crest point of the subtropical high deflects to the east, the number of glaze days in Nanyue is greater, and vice versa. The subtropical high varies ahead of cold and warm winters. The findings give evidences and references to glaze forecasting in Nanyue Mountain.
