... Why? Because the earth is rotating, and we are on the that rotating reference frame. The Coriolis force arises because the earth is an acccelerating frame of reference. It can be defined as Fcor = v f = v 2Ω sinφ, where Coriolis parameter, f = 2Ω sinφ, with angular speed of the Earth’s rotation, Ω = ...
