Re: How to find out two monthly mean....

Hello,
You can use runave or runave_Wrap to do this:
http://www.ncl.ucar.edu/Document/Functions/Built-in/runave.shtml
http://www.ncl.ucar.edu/Document/Functions/Contributed/runave_Wrap.shtml

for instance, starting off with your data array, and assuming the first
month of the data is January and the last is December:

temp = runave_Wrap(data(lat|:,lon|:,time|:),2,0)
data_djavg = temp(:,:,11::12) ; grab December timestep, which
represents Dec/Jan average
delete(temp)
delete(data)

Take a look at the documentation for the different possible values of
opt. In the above example i set opt to 0, and thus the last
December/January average will be set to _FillValue as January is not
present.
Hope that helps.
