中文摘要: 应用青藏高原东部17个测站1957~1988年秋冬季(11~2月)平均积雪深度及积雪日数资料,分析了积雪深度及积雪日数异常年夏季500hPa高度场的不同分布形态,同时对照登陆及影响福建的热带气旋偏多年及偏少年500hPa高度场的分布特征,得出青藏高原秋冬季积雪深度偏小(大)年夏季热带气旋频数偏多(少) ,而积雪日数偏多年,夏季热带气旋频数偏少。
Abstract:Based on fall-winter depth of snow and days of snow lying at 17 stations in the eastern part of the Tibetan Plateau from 1957 to 1988,the different distribution characteristics of the average geopotential height at 500hPa level in summer were respectively analyzed when the depth of snow and days of snow lying were anomalous.The distribution characteristics of the average geopotential height at 500hPa level when the tropical cyclones affected Fujian more or less was compared.The two distribution characteristics were similar.The result indicates that the frequency of tropical cyclones affecting Fujian will be increased(decreased)when the fall winter depth of snow is more(less),when the fall winter days of snow lying is more,the frequency of tropical cyclones will be decreased.
