Outline and discuss the phenomena called El-Nino. Discuss the causes of it, why it is called El-Nino, how it effects the productivity of the South Western coast of South America, how it effects the climate of the South Eastern coast of the U.S, and why it causes food shortages in developing countries

Discuss the homework question"what effect will global warming have on the climate of England and Western Europe?"
Outline how increased salinity due to glacial melting, along with thermohaline currents will actually decrease the temperature along the western European border.
Answer in class end of module questions 1-5

Discuss upwellings and their effects on productivity due to nutrient movement upward.
Introduce thermoline circulation which drives the mixing of surface and deep water.
Outline and discuss the 6 steps describing how it works, and then condense it into 2 processes.

Discuss the driving forces behind ocean currants.
Describe, examine, and explain the pathways of surface ocean currents, how they affect the climatic conditions of the land masses adjoining them.
Discuss the effects of temperature, prevailing winds, Coriolis effect, salinity, and continent location have on the current and the current has on them.

Review Hadley air currents.
Discuss the intertropical convergence zone.
From a diagram, list and discuss the polar cells and the Ferrell cells.
Discuss the rain shadow effect, as air moves from the oceans to a mountain range and then over the range to the leeward side, creating an arid region.

Discuss the response to change in air pressure on air currents.
Indicate that as air rises, pressure decreases, volume increases and the temperature decreases.
Define and explain adiabatic cooling.
Show the reverse as air sinks.
Define and explain adiabatic heating.
Discuss and show using diagrams how air currents move at the equators setting up Hadley cells.

Review the first2 properties that determine circulation.
Examine the concept of density from a chemical and physical point
Determine the effect density has on the rise and fall of air currents.
Discuss saturation point and relate it to density and air temperature

Review HW question answers.
Discuss how air properties affect the amount of moisture it can hold. Relate how unequal heating causes air to circulate upward into the atmosphere. Examine how air currents travel over mountains and cause different climates to exist on each side.
List and discuss the 4 properties that determine how air circulates: density, water capacity, and changes in pressure.
