中文摘要: 夏季旱涝与冬季环流关系密切。亚洲地区冬季纬向环流异常偏强,经向环流偏弱,同时1月的极涡所在纬度(简称极涡纬度)偏南时,极易造成赤峰地区夏季洪涝;相反,纬向环流偏弱,经向环流偏强,同时1月份的极涡纬度异常偏北时,极易造成赤峰地区夏季干旱。据此,把冬季环流进行分型,预测赤峰地区夏季旱涝。
中文关键词: 环流型，环流指数，极涡，夏季降水
Abstract:Winter circulation and summer drought and flood is closely related.When the longitudinal circulation in winter is unusually strong the meridianal circulation is weaker.Meanwhile,when the north pole ovrtex tends to the south in January flood and drought would be caused easily in Chifeng area in summer.
