摘要

Abstract

This paper presents the following data-based hypothesis on the mechanism of the EI Niño-Southern Oscillation (ENSO) cycle: during the warm phase of ENSO

there are weterly wind anomalies over the equatorial west-central Pacific and the sea surface temperature (SST) in the equatorial east-central Pacific is higher. The latter can strengthen Hadley circulation

and the west component of the Hadley circulation anomaly may cause southerly monsoon circulation. When the monsoon is a southerly anomaly

SST in the South China Sea (SCS) becomes higher. When the SCS gets warmer

the atmospheric convection will move to it

and then easterly anomaly wind will occur over the western Pacific. A cycle is completed. This hypothesis was used to construct an analogical oscillator model that produces ENSO-like oscillations. The negative feedback mechanism of the hypothesis is SST anomaly in the SCS. This negative feedback mechanism is quite different from others proposed before

is not within the Pacific and does not depend on ocean waves and their boundary reflection.
