INDS LOFT
Winds Aloft data shows the forecasted wind speed and direction at the surface
and at selected altitudes. Altitudes can be displayed in 3,000-foot increments up to
42,000 feet MSL.
Winds Aloft are displayed using wind barbs or a wind streamline depending on
the selected range. The wind barbs indicate wind speed and direction. The wind
streamline indicates wind direction with arrows.
The wind barbs always point in the direction the wind is coming from. The wind
speed is depicted using flags at the end of the wind barb. A short wind flag is 5 knots,
a long wind flag is 10 knots, and a triangle flag is 50 knots.
