Wind Barb
A Wind barb chart uses wind barb shapes to indicate wind speed and direction.
Speed is indicated using "flags" on the end of the barb:
- Each half of a flag depicts 5 knots (5.8 mph).
- Each full flag depicts 10 knots (12 mph).
- Each pennant (filled triangle) depicts 50 knots (58 mph).
Direction is indicated by orientation of the flags on the barb; the flags point in the direction of the source of the wind. For more information, see Information about wind barbs from the National Weather Service.
Features | Quantity | Notes |
0 | | |
Maximum of 6; 4 are required. | Lon, Lat, Speed, and Direction are required. |
- Lon - AVG longitude
- Lat - AVG latitude
- Speed - AVG a80m_Wind_Speed
- Direction - AVG a_80m_Wind_Direction
You can increase or decrease the number of barbs in the right panel. Here, barb number is increased to the maximum to provide a more contoured visual.
Using the optional Color measure, you can add more information to your Wind barb chart. For example, the following figure shows a Color value of a AVG a2m_Relative_Humidity to provide humidity information for the air, with yellow indicating areas of higher relative humidity. Adjust the Color Palette to change how the Color measure is represented.
