  1. What are some effects of earth heating?

  2. Solar Energy Intensity

  3. Solar Energy

  4. Thermal Energy distribution in the lower troposphere

  5. Energy absorption by land and ocean Angle of incident solar rays varies with latitude and season (Earth axis tilt) Daily hours of sunlight varies with season Specific heat differences causes local convection cells on land, between land and ocean, and in ocean Convection currents redistribute TE Vertically to Poles in global cells between locations on land or land and ocean/sea Rapid ground-heating causes mirages and thermals Rapid ground-cooling causes dew or frost

  6. Influence of land on atmosphere creates air masses and frontal boundarieshttp://www.physicalgeography.net/fundamentals/7r.html

  7. Boundary Layer (0-2km altitude) Pressure gradient winds respond to pressure gradients in air masses, surface friction, and coriolis effecthttp://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/fw/grad.rxml Note: above 2 km, winds parallel isobars Weather Map of surface winds http://ww2010.atmos.uiuc.edu/(Gh)/guides/maps/sfc/slp/sfcslpvec.rxml
