General Circulation 1

An anticyclone type circulation is associated with...

• low pressure and sinking air

• high pressure and sinking air

• low pressure and rising air

• high pressure and rising air

What causes warm air to rise?

• the fact that it's less dense than cold air

• The fact that it weighs more than cold air

• The fact that it has higher pressure than cold

• the fact that its more dense than cold air

What causes wind to blow?

• Differences in longitude

• Shock waves from clouds

• Differences in air temperature and pressure

• The rotation of the earth

In the single cell circulation of the earth the main surface winds in the southern hemisphere are

• north to south

• west to east

• east to west

• south to north

The reason why global winds flow from east to west and west to east, but not north to south, or south to north.

• Bernoulli's principle

• Coriolis effect

• high pressure

• low pressure

Where does the initial source of energy come from that creates winds?

• the moon

• the sun

• the earth's core

• the earth's rotation

The three cells that make up the earth's tricellular primary circulation model are the

• Ferrell cell, the Polar cell and the Gaol cell

• Hayley cell, the Ferrell cell and the Polar cell

• Polar cell, the Hadley cell and the Ferrell cell

• Tropical cell, the Hadley cell and the Ferrell cell

The term ITCZ is an abbrevaition for

• Inter-tropical conjunction zone

• Inter-territory conference zone

• Inter-tropical convergence zone

• Inter-tropical compression zone

The curving of air to the right in the Northern hemisphere is caused by ___________ and is called the _________ effect.

• Earth's rotation...Coriolis

• Earth's revolution...Coriolis

• Earth's rotation...Doppler

• Earth's revolution...Doppler

These winds blow from 30 degrees latitude in both hemispheres almost to the equator. (Hint: winds are named for the direction from which they blow.)

• easterlies

• westerlies

• trade winds

• doldrums
