[gradsusr] intraseasonal variability

[Mario Caffera]

You can use EOF  that is a way close to FFT. But you have to mount eofgrads. I couldn't.
You can find eofgrads at the net, it is free. You need grads 1.9 version
 
    good luck

Dear Sir/Madam, 
I am working on the intra-seasonal variability of Indian Summer Monsoon.

I am analyzing the precipitation time series.
How to find the different Oscillation of the time series using Grads?

Is it possible to calculate the FFT using Grads?

Thanks in advance

Pyarimohan
