Which term describes the lift coefficient (CL)?

Explanation:
CL stands for the lift coefficient, a dimensionless number that links lift to the flight conditions. It’s defined in the lift equation as L = 0.5 ρ V^2 S CL, meaning CL describes how effectively the wing generates lift at a given angle of attack, air density, speed, and wing area. The other terms refer to icing (clear ice), a weather feature (cold front), and a navigational heading (compass course), none of which describe lift production.
