Vocab. Atmospheric Circulation

A semipermanent jet over the subtropics is called the

• polar jet stream
• subtropical jet stream
• subtropical high
• trade winds

Circulation that results from the uneven heating of a fluid; the warmer parts of the fluid expand and rise because of their buoyancy, and the cooler parts sink.

• Hadley Cell
• Westerlies
• Easterlies
• Convection Cell

The thermally driven circulation system of equatorial and tropical latitudes consisting of two convection cells, one in each hemisphere. 

• Convection Cell
• Hadley Cell
• Horse latitudes
• doldrums

The dominant west-to-east motion of the atmosphere that characterizes the regions on the poleward side of the subtropical highs.

• Trade winds
• Polar front
• Prevailing Westerlies
• doldrums

The zone of general convergence between the Northern and Southern Hemisphere trade winds.

• ITCZ
• Polar Easterlies
• Polar front
• Ferrel Cell

A belt of calms or light variable winds and subsiding air located near the center of the subtropical high. Legend states when water supplies ran low for sailors, animals were the first to be rationed water. Dying from thirst or tossed overboard, these animals were sacrificed to conserve water for the men. They were then thrown overboard.

• chicken latitutes
• cow latitudes
• horse latitudes
• pig latitudes

Two belts of winds that blow almost constantly from easterly directions and are located on the equator toward sides of the subtropical highs.

• Doldrums
• Trade winds
• Polar jet stream
• Westerlies

The equatorial belt of calms or light variable winds lying between the two trade wind belts.

• Doldrums
• Trade winds
• Polar easterlies
• Westerlies

The stormy frontal zone separating air masses of polar origin from air masses of tropical origin.

• Subtropical Front
• Warm front
• Polar Front
• Easterlies

Several semipermanent anticyclonic centers characterized by subsidence and divergence located roughly between latitudes 25 degrees and 35 degrees.

• Polar Highs
• Subtropical Highs
• Polar front
• Jet streams
