Question

tal How does the tota! poleward transport of heat in the ocean compare w ith that in the atmosphere, according to Figure 1.5? tb> Over which parts ol the globe does the ocean contribute significantly more lo poleward heat transport, and over which parts does the atmosphere contribute significantly more?

Wind systems redistribute heat partly by the advection of warm air masses into cooler regions (and vice versa), and partly by the transfer of latent heat which is taken up when water is converted into water vapour, and released when the water vapour condenses in a cooler environment. The tropical storms known as cyclones or hurricanes are dramatic manifestations of the transfer of energy from ocean to atmosphere in the form of latent heat. The generation of cyclones, and their role in carrying heat away from the tropical oceans, will be described in Chapter 2.

Figure 1.5 Estimates of the contributions to poleward heat transport (red curve) by the ocean (solid blue curve) and the atmosphere (dashed blue curve). Positive values are northward heat transport, negative values are southward heat transport. The total heat transport was derived from satellite measurements at the top of the atmosphere, heat transported by the atmosphere was estimated using measurements of atmospheric heat fluxes, and the heat transported by the ocean was calculated as the difference between the two.

Renewable Energy Eco Friendly

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
