The Earth's uneven heating is due to the fact that the Earth is at a tilted angle. Also, the Earth is a sphere and parts of the world can't all be heated at once. One final example is Earth's optical orbit. It spins and circle in a pattern preventing the whole Earth receiving the same about of heat. A model that help explains this is when in class we held up a globe and had a flashlight shine at the globe. It showed which areas of the earth received direct heat unlike certain parts of the globe received little to none.

The Earth's rotation affects the movement of air and water masses. The way the Earth rotates creates certain movements of air to spiral and create a constant pattern. As well as the water masses, they're affected because of the motion of the Earth. The coriolis effect is when the air spins in a perpendicular way and creates weather patterns. We examined this through cutting out a circle piece of paper and putting a pencil through the middle of the paper. We spun the paper and used a water dropper to drop tiny pieces of water showing us how the water spun around the paper in a spiral effect. Hadley cells are when air rises at the equator and then drops down. Most deserts are found at 30 degrees N or S latitude due to the fact that there is direct sun light hitting those degrees warmer the Earth to an extensive heat.

There are prevailing global wind patterns due to the fact that the Earth is tilted at an angle and certain parts of the Earth receive more sunlight/heat than other sections. Such as the equator. The equator receives the most heat and the doldrums are formed there.  Global wind patterns are prevailing because of the heat the world receives.  As for the westerlies, the weather patterns and airline flights are affected. They are very powerful and can give the plan extra speed due to the strength of the winds. But, once the plane needs to except the wind pattern, it is very difficult because of its strength.

Wind patterns might change as a result of global warming because the wind patterns are affected by the climate of the world. Especially at the equator. This article helps support this statement. http://www.climatecentral.org/blogs/climate-in-context-global-warmings-potential-impact-on-wind-energy
