Understanding "Combo" Images
The "combo" images have combined the wind direction and wind speed into
one two-colored number. The first two digits (in yellow) represent the wind
direction without the last digit. The last two digits (in blue) represent
the wind speed in knots. For example, if the number was 1420, the wind
direction would be 140 degrees, and the speed would be 20 knots.
