GEOS 212 Lecture 13Outline of Last Lecture - Model of atmosphere circulation (differences between simple, non-rotating model and real Earth) - Hadley cells; Trade Winds, Westerlies, Polar Easterlies - Explanation for rainy at Equator and 60o N,S and dry at 30o N,S and poles. - Surface currents (gyres) -- simple diagrams, real currents -- FIVE reasons why they are important!1. Salinity,2. Temperature of seawater, 3. Control on climate (SW versus SE USA), 4. Carries heat from equator, 5. One of the main controls on life in the oceans - Gulf Stream video - Basics of energy transfer during evaporation and rainfall- Energy transfer on Earth by evaporation and rainfall- Lightning videoOutline of Current Lecture: Wind, Waves, and Surfing- Atmosphere also transports heat (with water vapor) = 20% of heat moved toward poles- Atmosphere model explains weather: High versus Low pressure weather prediction (see map)- Atmosphere also creates wind waves: low wind = small waves, high wind = tall waves- But can have waves and no wind = magic of waves travel long distances! Pattern of atmosphere motion today = correct?These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Pattern of wind today = correct? - Pattern of wave height and direction correct?- Early explorersCurrent
