Tri-cellular Model

Question 1

Hadley: Situated between equator and…

Answer 1

30* latitude in each hemisphere.

Question 2

Hadley: Air in contact w/ the thermal equator….

Answer 2

Is warmed, and rises creating permanent low equatorial pressure.

Question 3

Hadley: Trade winds are drawn into…

Answer 3

The low pressure belt at the equator.

Trade winds meet at the ITCZ.

Question 4

Hadley: Moist air warmed in the ITCZ rises in…

Answer 4

Strong convection currents.

Question 5

Hadley: As air above the ITCZ condenses, latent heat energy is released and converted into…

Answer 5

potential energy for upper troposphere winds towards the poles.

Question 6

Polar: Polar air is chilled at the ….

Answer 6

Ice caps.

Moving high pressure air at the surface towards more temperate latitudes.

Question 7

Polar: As air travels away from the poles, it has more space, moving into a larger area…

Answer 7

Therefore reducing pressure.

Causing low pressure between 50-60*.

Question 8

Polar: Low pressure air moves towards the poles again….

Answer 8

At a high altitude.

Question 9

Polar: Directly ……… Induced

Answer 9

Thermally

Question 10

Ferrel: Not directly……….. induced but consequently adjacent….

Answer 10

Thermally.

Adjacent to thermally induced cells.

Question 11

Ferrel: Where is the Polar front?

Answer 11

It is the point where warm air from the ferrel and Polar cells rise to the tropopause, where it then moves towards the equator.
