Earth rotation and climate dynamics: Theory of oscillations

Considering the variation of the Earth's rotation rate and applying the hor izontal equations of motion to the geophysical fluid in low latitudes, the influences of the earth's variable rotation on the atmospheric and oceanic oscillations are analyzed. It is shown that the variation of the earth's ro tation rate affects directly not only the oscillatory period of atmospheric and oceanic oscillations, but also the anomaly of zonal wind and current. Therefore, the variation of the earth's rotation rate is a significant fact or in global climate variability.
