A Correct answer
Explanation

Winds aloft (upper atmospheric winds) are standardly measured and reported in knots for speed and true direction (not magnetic) for azimuth. True direction is measured relative to true north (geographic north pole) rather than magnetic north, which varies with location and time. This standardization allows for consistent navigation and flight planning across different regions and magnetic variations.
