由使用二维的风地异例和蒙特卡罗模拟实验计划的显著性检验，意义在关系风地异例展示 reinvestigated 洪水 / 干旱在期间每年在华南的第一雨季。结果证明在 LakeBaikal 和中央印度洋的东北上的那西方的和平的副热带的高度和风异例是重要因素。在在 1 月的北印度和在三月的西北太平洋上的风异例可以是强壮的预言信号。学习也证明在华南的降雨与在三月在北太平洋上提起的重力势高度有一种靠近的关系。

英文摘要：

By using the significance test of two-dimensional wind field anomalies and Monte Carlo simulation experiment scheme, the significance features of wind field anomalies are investigated in relation to flood/drought during the annually first rainy season in south China. Results show that westem Pacific subtropical high and wind anomalies over the northeast of Lake Baikal and central Indian Ocean are important factors. Wind anomalies over the northem India in January and the northwest Pacific in March may be strong prediction signals. Study also shows that rainfall in south China bears a close relation to the geopotential height filed over the northern Pacific in March.
