The soundings below show temperature (in red) and dew point (in green) at decreasing pressures (increasing heights) throughout the atmosphere.

Winds (in knots; 1 knot = 1.15078 mph) are shown at right.
Pennants or flags correspond to 50 kt, long barbs represent 10 kt, and short barbs represent 5 kt. Winds are also colored by magnitude.
The shaft points to the direction from which the wind is blowing. More information about wind barbs can be found here.
