ON 3.5-YEAR COUPLED OSCILLATION BETWEEN NORTHERN OSCILLATION AND SEA SURFACE TEMPERATURE OF THE EQUATORIAL PACIFIC

In this paper,we have analyzed the processes of temporal and spatial development in the interaction between the Northern Oscillation and the sea surface temperature of the cquatorial Pacific.It is revealed that between them there is a closed negative feedback process and the whole period including their influence,feedback and adjustment to each other is about 3.5 years.Furthermore,we have discussed the physical processes responsible for various links between the Northern Oscillation and the sea surface temperature of the equatorial Pacific.A physical model on 3.5-year coupled oscillation caused by the air-sea interaction in the tropical Pacific is postulated.
