摘要
用显式完全平方守恒差分格式及其改进分解算法对南海月平均流和海面起伏进行了数值模拟，与隐式完全平方守恒差分格式相比，计算时间可省３—５倍，具有良好的时间效益，而且，其计算效果不比隐式完全平方守恒差分格式差。因此，显式完全平方守恒差分格式及其改进分解算法具有良好的实用价值。
he explicit square conservative scheme and the improved splitting method are applied to the simulations for the monthly mean currents and surface elevations of the South China Sea.The time benefits of the scheme are much better than that of the implicit square conservative scheme because the simulating speed of the explicit scheme is 3 to 5 times as large as that of the implicit scheme, and the computing results the explicit scheme produces are no worse than that of the implicit scheme. Therefore. the explicit square conservative scheme and the improved splitting method are useful and practicable.
