Global Circulation Cells
There are 3 in the northern hemisphere and 3 in the south
What is a Convection Cell?
We live in this layer of the atmosphere
What is the Troposphere?
The winds appear to "veer" off to the left in this hemisphere
What is the Southern Hemisphere?
This brought sailers to the New World
What are the Trade Winds?
This is the ultimate reason we have to adjust our altimeter settings as we fly cross country (pressure changes)
What is uneven heating of the Earth/Atmosphere?
This cell starts at the equator and travels to 30 degrees
What is a Hadley Cell?
This traps radiant energy, heating the Stratosphere
What is Ozone?
High pressure cells rotate this direction due to the Coriolis Effect
What is clockwise?
This high speed ribbon of air lies between the Hadley and Ferrel Cells
What is the Jet Stream?
These lines connect points of equal pressure
What are Isobaric Lines?
Sailers used to throw horses over the side to conserve food & water, giving this latitude line it's name of Horse Latitude
What is 30 degrees?
This is the coldest layer
What is Mesophere?
Air tends to follow a path, always moving this way...
What is from High pressure to Low pressure?
These winds blow from West to East and took sailors back to Europe between 30 degrees north & 60 degrees north
What are the Westerlies?
This causes the surface winds to vary from the direction of winds at 5,000 feet
What is friction with the Earth's surface?
The air in this cell travels from 30 degrees to 60 degrees
What is a Ferrel Cell?
This is the boundary between the Stratosphere and Mesosphere
What is the Stratopause
Winds between the equator & 30 degrees are referred to as...
What are the Trade Winds?
As land cools off at night due to it's low specific heat, the wind blows from the coast out to sea
What is a Land Breeze?
This describes a warm air mass that is rising
What is Low Pressure?
The area around the equator was hard to sail in as the air was usually rising, making it difficult to sail
What are The Doldrums?
99.5% of moisture is found in this layer
What is Troposphere?
This is the descending air/wind that travels north from 30 degrees north latitude
What are the Westerlies?
Air moving up the slope of a mountain
What is Valley Breeze?
An elongated area of low pressure
What is a Trough?
