analyzing climatological time series (updated)

[Simon Krichak]

Dear Gradsusr Members,

I am currently analizing results of a 100 y (1960-2060) climate simulation experiment. I want to draw graphs with time variations of difference between area averaged seasonal precipitation for each year after 2000 and that for
 the current climate (30-year mean). The script I wrote (also attached is the monmask.gs by Wesley Ebisuzaki) seems to be producing wrong results - in the example attached the two graphs for SON and MAM are almost identical.
What is wrong in my actions?
 
Regards, Simon
