UCLA AOS Final Spring 2024 Exam with Correct Solutions

UCLA AOS Final Spring 2024 Exam with Correct Solutions A greenhouse gas is a gas that... - Answer -significantly absorbs infrared radiation. Choose the best definition of convection. - Answer -Air warms, becomes less dense, and rises Which of the following shows the correct listing of the contributions of greenhouse gasses to the greenhouse effect in the atmosphere from highest to lowest? - Answer -water vapor, CO2, methane What is the most important reason the poles receive less sunshine (or solar radiation) than the tropics? - Answer -At higher latitudes, the angle between the earth's surface and the rays of sunshine is more oblique, spreading the sun's rays over a larger area. Which of the following forms of radiation has the shortest wavelength, and therefore the highest energy? Infrared radiation, Microwaves, Visible Light, Radio waves - Answer -Visible light Which of the following is a true statement? - Answer -Ultraviolet radiation is more energetic than infrared radiation. What best describes the root cause of the global atmospheric circulation? - Answer -The equator receives about 2.5 times more sunshine than the poles, creating a large equator-to-pole temperature difference. Surface currents in the ocean are largely caused by: - Answer -friction between moving air (winds) and the water. Relative humidity... - Answer -is determined by the amount of moisture in the air and the air's temperature. The intertropical convergence zone is associated with ... - Answer -The rising branch of the Hadley cell, resulting in a band of clouds throughout the tropics. What physical process can be explained without invoking the Clausius-Clapeyron relationship? - Answer - surface albedo feedback For deep ocean convection to occur, surface waters should have: - Answer -high salinity and low temperature A decrease in low clouds with global warming creates two climate feedbacks, one acting on the albedo, the other on the greenhouse effect of the low clouds. Which of the following is correct? - Answer -The albedo decreases, leading to stronger warming of the surface Which climate region has the highest salinities at the surface ocean, in part due
