摘要
分析了从上一年夏季以来 5 0 0 h Pa高度距平场的持续变化对当年长江中下游地区汛期降水的影响。结果表明 ,前期副热带地区高度距平累积指数与长江中下游地区汛期降水有密切的关系 。
The influence of 500hPa geopotential height anomaly sustained fluctuation last summer on flood season rainfall in the middle and lower reaches of Changjiang River was studied.The results indicate that the anomaly accumulation index in subtrotical area is related to flood season rainfall in the middle and lower reaches of Changjiang River and rainfall distribution in China.
