Presentation Transcript


  1. Composition of our air/atmosphere • Layers of the atmosphere • Pressure/density differences  CONVECTION CURRENTS

  2. Beginning with the SUN an Energy Budget is created • Earth receives shortwave radiation • Absorbed, reflected, or scattered • Earth then reflects/scatters back radiation to space • OR the absorbs the heat • Which is then reflected back as longwave radiation • OR used for life processes

  3. 4. Greenhouse Effect • Greenhouse gases: CO2, CH4, H20, O3, CFC’s, NO’s  Warms planet like a blanket

  4. 5. Ozone Layer • Made of O3 • Stratosphere – protects us from UV rays • Troposphere – harmful to breathe

  5. Due to • An uneven heating of Earth’s surface (land vs. water vs. ice  amt reflected vs. absorbed) • Pressure differences (moving from HIGH to LOW) ALL of that  CONVECTION CURRENTS

  6. 6. Atmospheric circulation (moving from H  L) Starting with the Coriolis Effect Circulation in the atmosphere is effected by the tilt of the axis.

  7. 7. Global winds • Trade winds • Westerlies • Polar Easterlies • Doldrums/Horse Lat’s (zones of H/L pressure) • Convections cells = Hadley Cells, Mid-latitude Cells  Jet Streams and Local Winds
