GEOS 212 1st Edition Lecture 12Outline of Last Lecture - Dynamics within oceans driven mainly by atmosphere processes- Atmosphere = ~10 km thick Gases = Oxygen, Carbon Dioxide, Water vapor (plus Nitrogen, Argon, Hydrogen) - Light-temperature-pressure changes with elevation - Evaporation of water (requires energy to evaporate) - Condensation of water (e.g., rainfall) releases energy (wind, turbulence, lightning, etc.!) - Atmosphere = huge transport of water & sun energy- Energy is transported within water vapor!! - Origin of rain and storms in Tucson- Humidity as an indicator of water in atmosphere - Sun energy on fixed- Earth and spinning Earth - Simple circulation in the atmosphere (2 cells) - More complex circulation Coriolis force/effect Wind patterns on - Earth Real circulation - Wind belts- Early explorersOutline of Current Lecture: Climate, Surface Currents, Heat TransportThese 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.- 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 videoCurrent Lecture:
