| 摘 要： | 根据珠江口气象站风速与潮汐站潮位资料,对1955～1998年12次El Nino过程的珠江口季风强度与海平面变化特点进行合成分析,结果表明,El Nino发生前一年冬季,珠江口冬季平均风速较常年值大0.4 m/s,El Nino发生当年,月平均风速也普遍大于常年,而月平均海平面则普遍较常年偏低,其中10与11月份负距平为6 cm左右。东亚地区的季风异常对珠江口海平面异常有着重大的影响。

| Abstract: | Making comparisons with 1982/1983 strong ENSO event,this paper revealed some characteristics such as rapid onset,the large intensity,and sudden retreat of 1997/1998 warm episode. Furthermore,the features of intra-seasonal oscillation related to the onset of ENSO episode were also discussed. |
