本文研究了东亚夏季风低频振荡与长江中下游旱涝的关系。研究表明，南海夏季风强增水年30~ 60 d的低频振荡最为显著，易引起长江中下游洪水。相反，在南海夏季风弱增年，10~ 20 d的低频振荡比30~ 60 d的低频振荡更活跃，更容易引起干旱。季风涌低频振荡的传播对长江中下游降水的中长期预报具有重要意义。
The relation between the low frequency oscillation in East Asian summer monsoon and the drought and flooding in the middle and lower valley of the Yangtze River is studied in this paper. Our study shows that the low frequency oscillation of 30～60d is the most remarkable in the strong summer monsoon surge years in the South China Sea and easily causes the flooding in the middle and lower valley of the Yangtze River. On the contrary, in the weak summer monsoon surge years in the Southern China Sea, the low frequency oscillation of 10～20d is more active than that of 30～60d and easily causes the drought. The propagation of monsoon surge low frequency oscillation is important to the precipitation’s medium and long range prediction in the middle and lower valley of Yangtze River.
