Unformatted text preview: AOSC 200 Lesson 14 Oceanography The oceans play three important roles in determining weather and climate First, they are the major source of water vapor for precipitation. This drives the hydrological cycle. Water vapor is also the source of the latent heat that, when released in condensation, is the driving force behind severe weather. Fig. 8-1, p. 210 Energy gains and losses in the oceans Oceanography Second, they exchange heat with the atmosphere. The previous slide showed the net energy gains and losses in the oceans. On average the ocean gains energy in the summer and loses energy in the winter. The oceans cool the atmosphere in the summer and heat the atmosphere during the winter The oceans act like a thermostat. Fig. 8-2, p. 211 Oceanography Third, the oceans transport energy poleward. The Pacific basin and the North Atlantic basin have two major currents that transport heat to the Pole. The Gulf Stream The Kuroshio Current These will be discussed later.
