Abstract

The authors investigate the relationship between ENSO events and regional climate anomalies around the Xisha Islands during the last 50 years. They find that there is evident correlation between ENSO events and the regional climate anomalies. There is a significant positive correlation between air-temperature anomalies and ENSO index (MEI). Power spec-tral analysis shows that the temperature anomalies have similar cycles to the ENSO index. Regarding to rainfall, the annual precipitation in La Niña years is much more than that in El Niño years. As to tropical cyclone, its frequency during El Niño is significantly lower than that during La Niña.

Key words： ENSO index; Xisha Islands; air temperature; rainfall; frequency of typhoon
