Meridional average of pressure levels data

[Lee and Amy Byerle]

Hyacinth,

How about:

open rean2.ctl
set z 1 17
set lon -60 10
set t varying (t1 to tlast)

define umer=ave(uwnd,lon=-90,lon=90)
set lon 1  (so that only lat, lev, and time are varying)
d umer  (loops through all times, plots lat vs z-dim)

Best regards,
Lee
