Upper Level Wind Map. UpperAir Patterns METEO 3 Introductory Meteorology Wind speed is calculated by adding all of the shaded triangles (50 kts each) and barbs (10 kts for full barb and 5 kts for half barb) on each flag The Jet Stream map shows today's high wind speed levels and jetstream directions

Jet; Northern Hemisphere Jet; NCAR Upper Air; Univ Surface and Upper Air Maps; Today's Maps; The 00z maps are produced at 01z using the available upper air data with a first guess from the 18z NAM 6-hour forecast for the objective analysis
7(q) Upper Air Winds and the Jet Streams
The Wind maps depict the analysis or forecast of upper level winds The 12z maps are produced at 13z using the 06z NAM 6-hour forecast as a first guess for the objective analysis. Current WInds The Current Wind map shows the current wind speed and direction for the most recent hour.

Lecture 25 Forces that cause upper level and surface winds. For example, two triangles and one barb would represent a wind. The Jet Stream map shows today's high wind speed levels and jetstream directions
