The Coriolis Effect
The Coriolis Effect Defined: What in the World is it?
Warm Air Rises and Cold Air Falls- Why?
What is the general pattern of wind currents on the globe?
The general pattern of wind currents on the globe is
What is a convection current?
A convention current is when air flows around an area and back to the source. The warm air becomes less dense and rises, whereas the cold air becomes denser and falls.
Global circulation is driven by which two processes?
Global circulation is driven by uneven solar heating and the rotation of the earth.

Notes:
Due to the Earth's round shape, the rotation speed is fastest at the equator, and slowest near the North and South Poles. Air increases in speed as it reaches the equator. As a result, air masses appear to go to the right in the northern hemisphere, and appears to go to the left in the southern hemisphere.
Density- Temperature and water vapor have a great influence air density. Humid air is less dense than cold air.
Pressure- Near the Earth's surface, air molecules are packed tightly together. As they rise, they begin to expand and cool. Cooler air masses hold less water than hot air masses.

Putting it all together
Define and explain...
Hadley Cells- When air expands in the equator, it loses moisture which is caused by expanding and cooling. Due to the Coriolis Effect, this created the Easternly Trades.
Ferrel Cells- The air is driven by uneven heating. This is influenced by the Coriolis Effect, and created the Westernly Winds.
Polar Cells-
Horse Latitudes-
Doldrums-
