Chapter 4- Variation in the Environment Solar Radiation and Global Pattersn o Zenith- sun’s highest position each day o With respect to latitude The equator is tilted 23 ½ degrees with respect to the path the earth follows in its orbit around the sun Seasonal variation increases with distance from the equator Northern hemisphere temps vary more than the southern hemisphere due to more water being in the southern hem, which regulates the temps to more constant levels Solar equator- parallel of latitude lying directly under the sun’s zenith, reaches 23 ½ N on June 21 and 23 ½ S on Dec 21 o Water vapor Equilibrium water vapor pressure- the evaporation of liquid and condensation of vapor to maintain a balance o Hadley circulation and coriolis effect Hadley circulation/ Hadley cell- Warming air expands, becomes less dense, and travels north/south and then up. As it reaches the upper atmosphere, it cools, condenses, travels in a circle towards the equator Ferrel cells and then polar cells do the same thing in opposite ways
