Thanks Scot and Luis. I have been over the Singleton site many times and have found much useful info there, but alas no GRIBs that include both the 500mb height AND wind at that height. Ditto for the WeatherNet site which does have both the isobars and wind, but not in one combined GRIB. I have had limited success creating my own "Custom" GRIBs with the GMN GRIB combiner, but that is a kludgy solution at best. What mystifies me about this is the the fact that the NOAA 500mb analysis chart is a very well known and useful tool for forecasting in that it shows the location of the 5640mb isobar and the upper level wind associated with it, both excellent indicators of storm tracks and and the speed of those storms.

actually its a fairly simple thing to create a combined grib file in wxnet. here is what you do... you create a batch and place your 500mb wind and 500 ht in it. You can also add whatever other grib files you want. Then do a right click on the batch and click on combine grib files after download and give the file a name.

that is it.

now hit go. you will have a nice combined grib file when the download completes.

this works for any grib file set in wxnet.

check out the instructions for more info.

or e-mail me.

thanks,
