Hi Ron,<br>
<br>
I found a source code (fortran 90) for objective trough/jet in gridded<br>
data. It was developed by G. Berry (SUNY) to get African easterly waves<br>
activity. You can get it here:<br>

<br>
The Input data can be streamfunction or zonal and meridional winds. The<br>
output consists of several fields including trough and jet axes in both<br>
easterly and westerly flow. I've attached an example output plotted with<br>
GrADS.<br>
<br>
I hope this can help you or at least give you an idea. Good luck.<br></blockquote><div><br></div><div>It would be nice to have this as an extension. Any volunteers?</div><div><br></div><div> Arlindo</div><div><br></div>
