Dear NCL users,

I used the function "gsn_vector" to plot the jjas mean Hadley circulation

and I got the correct plot. But to have more control over the plot ( I have

to get coordinate in X and Y), i used the "gsn_csm_vector" function. But in

this case I getting a different plot. Why this difference is coming and what

is the solution? In the following script I changed only gsn_vector to

gsn_csm_vector.Any help would be greatly appreciated.

I used the ncep v wind and omega. For scaling I multiplied the omega with

-100

Thanks in advance
