By using data of index of subtropical high between 1951 and 2000, we discovery that it has 3. 5 and 2. 5 year oscillation, it accords with precipitation oscillation and show that it is principle effect of precipitation. analysis of vorticity and divergence show that subtropical high affect precipitation, drought and flood by 500 & 700hpa vorticity and 850hpa divergence. vorticity and energy index of subtropical high are sign of chinese precipitation, drought and flood
利用1951年至2000年副高特徵指數及渦度、散度、水氣通量散度物理量,小波分析發現,西太平洋副高面積和強度有3 . 5年周期,北界指數有2 . 5年和5年周期,這和中國降水、旱澇變化趨勢一致,說明副高是影響降水主要因素之一。
