The magnitude of the Coriolis force (F_c) is given by F_c = 2 * m * v * \u03c9 * sin(\u03c6), where m is the mass of the object, v is its velocity, \u03c9 is the angular velocity of the Earth&#8217;s rotation, and \u03c6 is the latitude.<br \/>\nStatement 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.<br \/>\nStatement 2: The term sin(\u03c6) in the formula varies with latitude. At the equator (\u03c6 = 0\u00b0), sin(0\u00b0) = 0, so the Coriolis force is zero. At the poles (\u03c6 = 90\u00b0 or -90\u00b0), sin(90\u00b0) = 1 or sin(-90\u00b0) = -1, giving the maximum magnitude (directional deflection is opposite). Thus, the Coriolis force is maximum at the poles and absent at the equator.
