defining new variable

[Henrique Barbosa]

Wu,

You don't need to save the data, just plot it! Try this:

'mean=ave(ave(temp,lon=0,lon=360),t=1,t=1000)'
'd mean'

There's also an error in your script. When you use fwrite,
you must "display" the variable to have it written to the file.
And I think it would be better to fclose the file before a
new fwrite.

x's
