Look at CORIOLIS COEFFICIENT keyword. Hope this helps, Chi-Tuan

Hello Chi-tuan,

Thanks for your answer.Another quetion, when the area is large and I know the latitude of every point inside ,can I calculate Coriolis force of every node,like giving the latitude file of every node? Whether I have to transform to the longitude/latitude coordinated system?I ask this question because when researching some engineering in a sea area, the mesh hard to generalize in longitude/latitude scale.
