The reason the earth has uneven heating is because the earth is in the shape of a sphere so different parts of the earth will get more sun light and light rays will hit it differently. Also, the earth is spinning so some of the earth will be getting hit and other parts of the earth wont. The Coriolis Effect is the deflection of objects when they are in a certian part of the world. Counterclockwise is to the left and clockwise is to the right. The reason that most deserts are at 30 degrees is because that is where the sun hits the earth the most direct and the strongest. Prevailing winds are winds that blow predominantly from a single general direction over a particular point on the earth’s surface. The dominant winds are the trends in direction of wind with the highest speed over a particular point on the Earth's surface. Global Warming could cause the air pressure to change and therefore cause the wind patterns to change.
