The Science of Spin
Circulation Cells
100
These winds blow steadily from East to West in the tropical region between the Equator and 30° latitude.
What are the Trade Winds?
100
In this color-coded weather symbol, you will see a large blue "H".
What is a High-Pressure System?
100
This weather front is represented by a blue line with triangles on it.
What is a Cold Front?
100
The curving of global winds caused by the Earth’s rotation is called this.
What is the Coriolis Effect?
100
This circulation cell is located closest to the Equator (0' to 30')
What is the Hadley Cell?
200
These winds blow from West to East in the temperate region between 30° and 60° latitude.
What are the Westerlies?
200
In a Low-Pressure system, the air moves in this direction.
What is Rises (or Up)?
200
This weather front is represented by a red line with semi-circles on it.
What is a Warm Front?
200
Because of the Coriolis Effect, winds in the Northern Hemisphere curve to this side.
What is the Right? (East)
200
This circulation cell is located between 30' and 60' latitude.
What is the Ferrel Cell?
300
These fast-flowing, narrow air currents are found high in the atmosphere, not at the surface.
What are Jet Streams?
300
In a High-Pressure system, the surface winds flow in this direction relative to the center.
What is Outwards?
300
In science, if you add the Latin word "Nimbus" to a cloud's name, it tells you that the cloud is currently producing this.
What is Rain?
300
The Earth rotates in this direction when viewed from above the North Pole.
What is Counter-Clockwise?
300
This circulation cell is located at the very top and bottom of the Earth (60' to 90').
What is the Polar Cell?
400
These winds blow cold air from the poles toward the 60° latitude line.
What are the Polar Easterlies?
400
This type of pressure system is usually associated with "Dry and Stable" weather.
What is a High-Pressure System?
400
In a cold front, this type of air pushes under the warm air, forcing it up quickly.
What is Cold Air?
400
Someone standing here travels a longer distance in one day than someone standing at the North Pole.
What is the Equator?
400
At 30' North latitude, the air between the Hadley and Ferrel cells is doing this.
What is Sinking?
500
Long ago, sailors relied on these specific steady winds to help them travel across the seas to trade goods.
What are the Trade Winds?
500
Wind is created when air moves from an area of _____ pressure to an area of _____ pressure.
What is High to Low?
500
On the weather map, rain and storms are shown happening in what orientation/location to the cold front line.
What is Behind (or Along) the line?
500
Two things are responsible for creating global winds: The rotation of the Earth and this.
What is the Uneven Heating of the Earth (by the Sun)?
500
At the Equator (0'), the air is doing this, creating a Low-Pressure zone.
What is Rising?
