Statement 1: The formula shows that F_c is directly proportional to the velocity (v) of the moving object. Thus, it increases with an increase in wind velocity. This statement is correct.
Statement 2: The term sin(φ) in the formula varies with latitude. At the equator (φ = 0°), sin(0°) = 0, so the Coriolis force is zero. At the poles (φ = 90° or -90°), sin(90°) = 1 or sin(-90°) = -1, giving the maximum magnitude (directional deflection is opposite). Thus, the Coriolis force is maximum at the poles and absent at the equator. This statement is correct.
Both statements are correct.
