Consider an inertia current in the Atlantic at 40° S with speed U = 0.4 [m.s-¹]. = 1. What is the period of the inertia current in days and the radius of the inertia circle? (10 points) 2. Consider a surface particle following the inertia current. If at time t 0 [s], the particle is at location x(0) = 0 [m], y(0) 0 [m] in the f-plane, find the horizontal components of the particle trajectory r(t) and y(t). (10 points) Consider a body of water moving on earth's surface with a constant ve- locity vo = 1.5 [m.s-¹] along the y (north) direction, as observed from the earth-fixed f-plane(East- North-Up oxyz), at latitude 0 = 45°. Find the Coriolis acceleration in the earth-fixed oxyz. (10 points) x-component of the Coriolis inertia: Cx = pfv - pfyw y-component tof the Coriolis inertia: Cy=-pfu z-component of the Coriolis inertia: C₂ = pfyu
