Document Summary
Net radiation balance the total of incoming and outgoing radiation on earth equator from about 35 degrees n and s deficit is in the poles. Geographic regions of surplus and deficit in net radiation surplus is in the tropics and. Global heat transport tropics to poles heat gained in the tropics is transported poleward by the global circulation of air and warm ocean currents to heat higher latitude regions. Importance of atmospheric and surface ocean circulation helps maintain a long term energy balance. Wind (advection) horizontal air flow blows in response to differences in pressure wind speed is determined by the magnitude of the pressure difference over distance aka pressure gradient. Coriolis effect/force deflection most apparent in the path of an object moving longitudinally. General patterns of ocean surface currents function to transport thermal energy from the tropics toward the poles.
