What kind of weather can you expect from a high pressure system?

Clear skies, sunny weather.

200

It is sunny outside today, but cooler than it was yesterday.

How are convection currents formed in the air?

Warm air is less dense, so it rises.  Cold air sinks and moves in to take the place of the warm air.

Look at the map of South America.  Buenos Aires and Capetown are approximately the same distance from the equator and are both located on the coast. How does the air temperature of Buenos Aires compare to the air temperature of Capetown? Why? 

The air in Capetown is colder than Buenos Aires. At Capetown, only a little energy is transferred from the ocean to the air because the current is coming from the South Pole. At Buenos Aires, a lot of energy is transferred from the ocean to the air because the ocean current is coming from the equator.
