GEOL 150Lg Lecture Notes - Lecture 13: Northern Hemisphere, Ocean Current, Latent Heat
Document Summary
Atmosphere and ocean processes transport energy from equator to poles. Ocean moves by: wind driven circulaion (only 10% by volume) Coriolis: thermohaline circulaion deep water circulaion lasts hundreds of years. Latent heat- evaporaion and precipitaion releases heat into atmosphere. Water moving to higher laitudes become denser and colder due to evaporaion of water (more salt content) Forces that control wind: pressure gradient, gravity, coriolis (fricion?) Surface currents are strongly afected by: surface winds, earth"s rotaion, posiion of coninents. Surface ocean circulaion is governed by westerly and easterly winds.
