考虑地球自转速率随时间的变化，并应用描写低纬地球流体（大气和海洋）的水平运动方程，分析了地球自转速率变化对低纬大气和海洋振荡的影响．研究指出：地球自转速率的变化不但会直接影响低纬大气和海洋的振荡周期和振幅，而且会影响纬向风和洋流的变化，从而导致海温和海平面的变化．所以，地球自转速率的变化是影响全球气候变化的重要因素之一．关键词##4地球自转速率;;气候变化;;大气和海洋的振荡
Taking into account the change of the Earth's rotation rate with time, and using the horizontal motion equation describing the low-latitude earth's fluids (the atmosphere and the ocean), the influence of the change of the Earth's rotation rate on the atmospheric and oceanic oscillations at the low latitudes is analyzed. The study shows that the change of the Earth's rotation rate will not only directly affect the oscillation period and amplitude of the low-latitude atmosphere and ocean, but also affect the variation of zonal wind and ocean currents, leading to changes of sea surface temperature and sea level. Therefore, the change of the Earth's rotation rate is one of the important factors affecting the global climate change.
