Poleward Flux of Momentum
qIn the tropical easterlies, eastward angular momentum is transferred from Earth to the atmosphere via frictional forces and mountain torque.
qThis westerly angular momentum is transported upward and then polarward into the Hadley Cell.
qEddies
then transport angular momentum
polarward and downward
into mid-latitude westerlies.
qIn the
mid-latitude, the westerly momentum
is returned to the Earth.
