Two questions

[Charles Seman]

Sajjad,

Please find attached pptn_anom.gs, pptn_Hovmuller.gs (and pause.gsf),
along with the GrADS pptn.ctl file.  "pptn_anom.gs" calculates and plots
JJAS time-averaged precipitation anomalies relative to a long-term
precipitation mean, while pptn_Hovmuller.gs calculates and plots a
Hovmuller-like map of latitude-averaged precipitation for latitudes
5N-35N, where the plot (x,y) = (longitude,time).  Please let me know if
you have any questions about these scripts...

I hope this helps,
Chuck
