Exam 2 ATMO 1300 Fall 2009 Chapter 3 1. Describe what happens to radiation from the sun as it enters Earth's atmosphere on its way to the surface in terms of absorption, scattering, reflection and transmission. (Remember we’re using the term reflection to refer to visible radiation reflected from the tops of clouds or from the earth’s surface). Some of the radiation from the sun is absorbed by the earths surface, some is scattered by gas molecules, some is reflected by the earths surface and tops of clouds and some is transmitted through the atmosphere 2. Describe what happens to the radiation emitted from the Earth’s surface. The long wave radiation being emitted from the earth is IR and most of it is absorbed by water vapor and carbon dioxide 3. Know the material in the section on Latent Heating. Know the three phase changes of water in your notes and whether energy is absorbed or released by the water molecules for each. Latent heat refers to the energy needed to change the phase of water

Unformatted text preview: -liquid gas: evaporation; energy is absorbed-gas liquid: condensation; energy is released-gas solid: deposition; energy is released *very important as an energy source in the atmosphere 4. Know the material in the section on variations in the energy balance. Energy balance between incoming and outgoing radiation; net gains or losses between incoming and outgoing radiation vary w/ latitude; net gain near equator, net loss near poles 5. Understand the role of greenhouse gases (water vapor and carbon dioxide) and clouds in controlling the temperature in the troposphere. Review the forecast problem we did in class when we were talking about water vapor and clouds as controlling factors on temperature 6. Know why water heats and cools more slowly than land. Water heats and cools more slowly than land because it has a higher specific heat than land; so it takes more energy to change the temperature of water than it does the temperature of land...
