Question

Considering the tropical Hadley cell. The circulation rises at 10°S, moves northward across the equator in the upper troposphere, and sinks at 20°N. Assuming that the circulation, outside the near-surface boundary layer, is zonally symmetric (independent of x) and inviscid (conserves absolute angular momentum about the Earth’s rotation axis), and that it leaves the boundary layer at 10°S with zonal velocity u = 0, calculate the zonal wind in the upper troposphere at (i) the equator, (ii) 10°N, and (iii) 20°N.
