Im looking at the winds aloft for some airports.

One gave an actual of 184 @07 and the aloft (3000ft) at 240@21 with following readings of a few degrees and speeds higher (and clockwise) than the previous ones.

Questions are:  is the 0-3000ft difference THAT different-it seems a big change for just 3000ft.  Does FSX:SE actually use the winds aloft data??  Should I be using something more modern for my weather (build 5870)??

 

Cheers

Hi,

Yes winds can certainly be that high/different between surface and 3000ft level, it all depends on conditions.  I've seen much higher even in some cases!  30kt delta at 3000ft last spring in Socal, for example, IIRC.  You can compare with actual sources, it should all be consistent with some fairly minor deviations.  If there's some discrepancy you are seeing, please report it (support ticket) along with the data showing that and we'll investigate.

 

ASN-SE definitely uses the aloft data as well as surface data, and works to provide a realistic transition between the two, with some advanced effects as well as vertical and horizontal interpolation.  See the user's guide for more info.

 

ASN-SE is quite old, our newer products have significant forward development and new features, with interface limitations depending on the platforms.  ASNP3D for P3Dv5 is the most recent and evolved.

 

many thanks.
