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。
Using data of wind speed from weather stations and tidal levels from tidal stations near the Pearl River mouth, composite study is carried out of monsoon intensity and sea level variation during 12 E1 Nino processes in 1955 ~ 1988. The result shows that the winter-mean wind speed is larger than normal by 0.4 m/s in the preceding winter and monthly mean speed is generally higher than normal in the current year of E1 Nino events, while the monthly mean sea level is lower than normal with negative anomalies of about 6 cm for October and November. Monsoon anomalies in East Asia poses significant influence on sea level anomalies at the mouth.
