主题: [SPAM] Re: [gradsusr] grads scripts operating


Dian,
First define your averaged u and v, then display result.  For example:


'define uavg=ave(u,z=36,z=46)'
'define vavg=ave(v,z=36,z=46)'
'd uavg;vavg'

this is my scripts for temperature average for layer 3 - 50 meter.
but when i try using for current(u;v) this is error.
i need help to make scripts average layer value like in temperature script for u;v variables.
