The magnitude of the Coriolis force is given by 2 ω v sin φ; it therefore grows with the speed (v) of the moving air, satisfying Statement 1. Because the term sin φ equals 0 at 0° latitude and 1 at 90°, the force is zero at the equator and reaches its maximum at the poles, so Statement 2 is also correct.
