Heating of Land and Water Land Heats up faster and Cools down faster than water
Winds Movement of air from an area of high pressure to an area of low pressure. Winds are caused by differences in air pressure. Differences in air pressure are caused by the unequal heating of the Earth.
Wind-chill factor- Measure of cooling. It combines temperature with wind speed. The name of the wind tells you where the wind is coming from. (South wind blows from the South)
Local Winds Sea Breeze- blows from ocean or lake Land Breeze- blows from land to a body of water.
Global Winds Global Convection Currents- Differences in air pressure causes winds to blow from the poles toward the equator.
Coriolis Effect Earth’s rotation makes winds curve to the right (clockwise) in the Northern hemisphere and to the left in the southern hemisphere (counter clockwise).
Air masses Air Mass- body of air that has similar temperature, humidity, and air pressure. Polar- cold Tropical- warm Maritime- form over oceans, humid Continental- form over land, dry
Air Masses Maritime Tropical- over ocean, humid, warm Maritime Polar- over ocean, humid, cold Continental Tropical- over land, dry, warm Continental Polar- over land, dry, cold
Isolines Lines on maps that connect equal measurements at a given time. There are three types: a)Isobar- equal atmospheric pressure. (mb) b)Contour lines- equal altitude. (m) c)Isotherm- equal temperature. (Celsius or Farenheit)
