[RegCNET] Re:how to calculate these

Hi,

Look for hcurl(), hdivg(), mag() functions in Grads. Those will suffice your needs.

In ferret you can write few lines at your own to calculate these e.g. hcurl in grads is vertical component of vorticity (rotation in other words) and this can be calculated in ferret using following formula:

let vor=v[x=@ddc]-u[y=@ddc] ! vorticity=dV/dx-dU/dy

and similary for other functions you can go......
