Concept 1: Examine the weight of air and the definition of air pressure in order to understand how air pressure is measured and how it changes with altitude.

Concept 2: Explain how the pressure gradient force, Coriolis effect, and friction influence wind.

Concept 3: Describe the movements of air and features associated with the two types of pressure centers.

Concept 4: Discuss the idealized global patterns of pressure and wind including the general atmospheric circulation in the mid-latitudes.

Concept 5: Describe how wind is measured as well as the development and importance of local winds.

Concept 6: Discuss atmospheric conditions and consequences of El Niño/La Niña and the global distribution of precipitation.
