摘　　要：科里奥利力是大学物理中的一个重要知识点,其表达式用到了线速度和转动角速度矢量积的形式,对地球转动参考系中物体的运动具有丰富的作用形式和效果。然而在三维立体的地球表面上分析其大小和方向,以及其对宏观物体如水流、大气的影响时相对比较复杂,初学大学物理的学生和研究者很难理解相关物理概念或对之形成清晰的物理图像。本文详细分析了科里奥利力在地球表面矢量投影的一般表达式,并定量分析了该力对一些宏观物体运动产生的影响,为相关物理课程的讲授和学习提供参考。Coriolis force refers to the vector product of velocity of the moving object and the angular velocity of the moving frame of reference,and is a very important knowledge point in College Physics.On the earth surface,due to the earth's rotation along its axis in an sphere coordination,the Coriolis forces exert on the moving object,such as the flowing water and atmosphere are complicated.Therefore it is difficult for an grade-one college student to form a clear physical image.This paper provides a detailed analysis of the general vector projection expression of the Coriolis force on the earth's surface and quantitatively analyzes the impact of this force on the motion of some macroscopic objects,providing a reference for the teaching and learning of related physics courses.
