黄山冬季气温分类及雪、雨凇和雾凇的气候分析

TYPE OF THE WINTER AIR TEMPERATURE IN HUANGSHAN MOUNTAIN AND ITS CLIMATIC ANALYSIS OF SNOW GLAZE AND RIME

摘要: 用对应分析方法对黄山1956～1996年冬季气温进行聚类分析。结果表明:Ⅰ类冬季气温特点,后冬冷于前冬,隆冬气温很高,冬季气温低;Ⅱ类特点,前冬暖后冬冷,隆冬气温很低,冬季气温正常;Ⅲ类后冬暖前冬冷,隆冬气温偏高,冬季气温高。Ⅰ类冬季降雪、积雪、雨凇和雾凇日数多;Ⅱ类冬季积雪日数多,降雪、雨凇和雪凇日数少;Ⅲ类冬季降雪日数正常,雨凇日数偏多,积雪和雾凇日数偏少。各类冬季降雪、积雪、雨凇和雾凇日数的冬季月分布差异明显。ENSO对黄山冬季气温有明显影响,ElNino年黄山多为暖冬年份,冬季平均气温正距平百分比18.8%。关于中高纬度和极区环流与黄山冬季气温关系也进行了初步探讨。

Abstract: Using correspondence analysis method the winter air temperature in Huangshan mountain is analysesed with the meteorological data from 1956 to 1996.Three types of winter air temperature and correspondence three weathers are discussed. An obvious inflence of ENSO on the winter air temperature is investigated.In general the winter in El Niño year is warmer than nomal.Pleion percent of the winter season mean air temperture in Huangshan are discussed.
