[gradsusr] Horizontal Temperature Gradient

[lpasmanoranjan]

Dear Users,
I would like to calculate horizontal temperature gradient. The following
script plots strange values. Perhaps I am making some mistake, would anyone
please check the script.

dtx = cdiff(t,x)
dx = cdiff(lon,x)*3.1416*6.37e6*cos(lat*3.1416)
d dtx/dx

Thank you.
