Document Summary

Climate long term pattern of weather. Weather = current condition (fucking snowing now) = 12 hrs of sunlight and 12 hrs of darkness insolation highest at 90 degree. ** earth orbit is not the same therefore can affect insolation. *** north part get sun when its away from the sun like us! Or when we are closer to it insolation hot air rises ---> pushed away from the equator. Since the hot air is being release, cold air from the north and south come to replace it. Air pocket ends up being protected stay warmer than surrounding air creates low and high pressure bands low pressure air is raising. High pressure air is cooling back to the surface going up hold less water. Hot air creates rain when it raises as air descends it can hold more water (absorb water from surroundings)
