Document Summary
Lls up the vast majority of the ocean basin: in the vertical direction, temperatures change most rapidly in the thermocline, the upper. February 10, 2017: sinking of water at high latitudes must be compensated by upwelling, in order to upwell, the water must become less dense through mixing, in-class problem, calculate average upward velocity. Assume global rate of deep water formation is ~40. Energy budget and atmospheric circulation continued: uneven solar heating, equatorial regions receive more heat per unit area because , higher incidence angle, spreads energy over smaller areas, implies that sunlight passes through thinner column of atmosphere, leading to less. Coriolis force: de ection is always to the right in the northern hemisphere and to the left in the southern. Geostrophic flow: affect marine life by bringing nutrients up from deeper waters, affect temperatures by transporting heat, rainfall by providing source of moisture.
