Poleward Flux of Moisture
qBoth the mean meridional circulation and eddies transport water and play an important role in determining the nature of the hydrological cycle.
qMoisture convergence in the tropics is dominated by the transport provided by the mean meridional circulation.
qThe subtropcs serves as source regions for water vapor.
qEddies remove water from the tropics and supply it to middle and high latitudes.
