The effect of rotating coordinates on fluid vortex motion isdiscussed in this paper. The appearance of this effect in potential vorticity is analyzed in geophysical fluid dynamics. The mechanism of vorticity production by coriolis force is investigated.%系统讨论坐标系的旋转对流体涡旋运动的影响,分析这种影响在地球物理流体力学相对涡度、速度环量及位势涡度方程的各种形式中的表现,以及与流体力学对应的Helmholtz方程的变形形式,通过分析,更清晰地揭示科氏力产生(或制造)涡度及其影响涡度变化的机理。
