A winds aloft forecast shows "2416". What does this indicate?
Choices
✓ Wind from 240 degrees true at 16 knotscorrect
The first two digits are direction in tens of degrees true (240), and the next two are speed in knots (16).
Wind from 160 degrees at 24 knots
The direction comes first (240), then the speed (16).
Temperature 24 C at 16,000 feet
This four-digit group is wind only; temperature would add two more digits.
Wind from 024 degrees at 16 knots
The direction is 240 degrees, read from the first two digits times ten.
Why
In a winds aloft forecast, 2416 means wind from 240 degrees true at 16 knots. Speeds over 100 knots are coded by adding 50 to the direction.
