Homework: 9 1. Holton 5.2 (Ekman layer solution for non-vanishing vg) 2. Holton 5.4 (Spin-down) 3. Holton 5.6 (Oceanic Ekman layer) (Hint: Assume ug and vg are both 0. Solve the Ekman layer equation as in class, but assume that the unknown coefficient in front of the exponential function is imaginary) 4. Holton 5.7 (Mass-transport in oceanic Ekman layer) (Hint: Calculate the vertical integrals of u and v. For the physical explanation, assume steady state, and that the only forces acting are the wind stress tau and the Coriolis force) 5. Holton 5.8 (Oceanic Jet) Also: Sketch u, v, and w as a function of y, and the cross section of the secondary circulation. (Hint: Calculate first w(De). Then use the continuity equation to calculate v by assuming that v is independant of z). 6. Holton 5.9 (Spin-down of oceanic jet) |
