A geostrophic current is achieved when this exactly balances with the horizontal pressure gradient force, and the Rossby number is the ratio of the inertial force to it. In a noninertial, rotating reference frame, it appears as a term given by the cross product of angular velocity and velocity in the rotating frame. For a velocity tangential to a sphere, its horizontal component is perpendicular to the velocity, and it thus causes circular motion

For 10 points, circular weather patterns on the Earth are thus caused by what fictitious force that produces opposite motion in the northern and southern hemispheres?
