Latitude (°)

On a spinning planet, anything moving freely appears to curve — right in the Northern Hemisphere, left in the Southern. This Coriolis deflection is zero at the equator and strongest at the poles. It steers winds, ocean currents, and the rotation of hurricanes, and it is why weather systems spin.

Governing equation

a_{C} = - 2 Ω \times v, f = 2Ω sin φ \propto sin (4 5^{\circ}) = 0.71

Reading this result: Deflection scales with sin(latitude), so at 45° the force is about 71% of its polar maximum, curving motion to the right (Northern Hemisphere).
