[gradsusr] How to use NCEP/NCAR reanalysis data

[Djordje Romanic]

Dear All,

Please would you be so kind to explain me how to perform the following
analysis. Namely, using the NCEP/NCAR reanalysis data for u and v wind
components (for any hight, say, at 500 mb) for the period from 1948 to 2000
I would like to:

   - I would like to average all monthly averages for the u wind
   component, for the above mentioned time period, and to draw it for the
   Europe,
   - I would like to average all monthly averages for the v wind
   component, for the above mentioned time period, and to draw it for the
   Europe.

As You can see, I would like to see the average zonal and meridional wind
components for the Europe in the [1948,2000] period.

Please, could you give me instructions how to perform these analyses using
GrADS, i.e. what commands should I use?

Thanks in advance.

Best regards,

Djordje
