How do you read upper wind charts?
They follow the format ddfftt, where dd is the wind direction (true), ff is the wind speed (in knots) and tt is the temperature (in degrees Celsius). Subtracting 100 knots from the speed and adding 50 to the direction indicate wind speeds from 100 to 199 knots. For example, 240 degrees @ 130 knots is coded 7430.
How do you read wind temp data?
A four-digit group shows wind direction, in reference to true north, and wind speed. a. The first two digits give direction in tens of degrees, and the second two digits are the wind speed in knots.

How do you read wind speed symbols?
Wind speed. A combination of long/short barbs and pennants indicate the speed of the wind in station weather plots rounded to the nearest 5 knots. Calm wind is indicated by a large circle drawn around the skycover symbol. One long barb is used to indicate each 10 knots with the short barb representing 5 knots.
