一、引言 众所周知,地球大气与海洋运动有许多共同之处,无论是海洋或大气,它们都受到重力作用及科利奥里力的作用,并且它们都有层结。因此,无论发生在海洋或大气的大尺度运动都具有准地转性、准水平性及准无辐散性。为了统一地研究发生在地球流体中运动的基本原理,近年来已逐渐发展起一门新兴学科——地球流体动力学。 随着计算机的发展,用计算机来模拟地球流体动力学中一些基本问题已在国际上日益发展,现已发展成为一门边缘学利——计算流体动力学。
I. INTRODUCTION It is well known that the Earth’s atmosphere has much in common with ocean movement, both in the sea and in the atmosphere. Both of them are under the influence of gravity and Coriolis force, and they all have layers. Therefore, the large-scale movement that occurs in the ocean or the atmosphere has quasi-geostrophic, quasi-horizontal and quasi-non-divergent properties. In order to study the basic principles of the motion occurring in the Earth’s fluid uniformly, a new discipline, geodynamics of the Earth, has been gradually developed in recent years. With the development of computers, computer simulation of some fundamental problems in the hydrodynamics of the earth has been increasingly developed in the world. Now it has developed into an edge learning - computational fluid dynamics.
