<br>
</div>it may depend on omega: when omega is positive vertical motion is<br>
negative ...: d vwnd;-omega.2*1.0e3<br>

</div>yes, e.g.:<br>
d mean(v,lon=50,lon=100);mean(w,lon=50,lon=100)*1000<br>
<div class="im"><br>

><br>
><br>
<br>
</div>yes: set gxout stream<br>
avoid skip: if different from 1,1 stream will not work<br>
<br>
bye bye<br>
