(a) Consider the case of a projectile launched from the North Pole toward the equator. With the aid of a diagram, show that the projectile is deflected westward (to the right as viewed from the launch point).
(b) Recalling that a projectile launched from the equator toward the North Pole is also deflected toward the right (eastward), show that the circulation around low-pressure systems is counterclockwise in the Northern Hemisphere.
(c) Which way do low-pressure systems circulate in the Southern Hemisphere?
