Winds aloft

Asked by: 449 views ,

Hello, I’ve been having trouble with the meaning of the blank spaces on the winds aloft, usually these blank spaces are at 3000ft/6000ft. I would be very appreciated if someone could explain that to me. 

Thank you !

    Winds aloft are not forecast for altitudes within 1500’ of a station’s elevation. So for an airport that is say 4,600’ above mean sea level, the 3,000’ and 6000’ winds aloft values will be left blank.

    Look at the station elevation. What winds wiukd you expect at 3,000 MSL in Denver where the surface is at almost 6,000 MSL?

    No “winds aloft” are forecast within 1,500 feet of station elevation.
