Pressure Belts
This latitude has rising air due to intense solar energy?
What is the Equatorial Low?
This cell is found between 0° and 30°.
What is the Hadley Cell?
These winds blow from east to west near the equator.
What are the Trade Winds?
In the Northern Hemisphere, winds deflect this direction.
What is to the right?
Deserts are common near this latitude.
What is 30°?
Air sinks at this pressure belt found between the Hadley and Ferrell cells?
What is the Subtropical High 30N/30S?
This cell is located between 30° and 60°.
What is the Ferrel Cell?
These winds dominate much of the United States.
What are the Westerlies?
The reason we have three cells instead of one giant convection cell.
What is Earth’s rotation?
Rising air at 60° often leads to this type of weather.
What is stormy or cloudy weather?
This pressure belt forms near 60° where warm and cold air meet.
What is the Subpolar Low?
Cold, dense air sinking at the poles drives this cell.
What is the Polar Cell?
If you stand at 45°N, surface winds likely blow from this general direction.
What is west to east?
In the Southern Hemisphere, winds deflect this direction.
What is to the left?
Rainforests are common at 0° because air is doing this.
What is rising?
If air is sinking and warming, cloud formation is likely to _______________________
What is decrease?
Energy for the Hadley Cell mainly comes from unequal heating between these two regions.
What is the equator and higher latitudes?
Trade winds curve west because of this effect.
What is the Coriolis Effect?
Coriolis effect is strongest near these latitudes where the wind is closest to the axis of rotation.
What are the poles?
The jet stream is found near this boundary between cells.
What is around 60° latitude?
A region at 30° latitude is experiencing persistent clear skies, dry air, and little precipitation year-round. Explain the atmospheric motion responsible for this pattern.
What is sinking air from the Hadley Cell creating a subtropical high pressure zone?
Explain why the Ferrel cell is considered an “indirect” circulation cell compared to the Hadley cell.
What is it is driven by interactions between the Hadley and Polar cells rather than direct thermal convection?
If Earth rotated twice as fast, predict how global wind belts would likely change.
What is winds would curve more strongly due to a stronger Coriolis effect, possibly creating more, smaller circulation cells?
Why is the Coriolis effect zero at the equator but strongest near the poles?
What is because rotational speed differences increase with latitude, and there is no horizontal deflection at 0°?
Major rainforests are located near 0° latitude. Explain how global circulation directly causes this climate pattern.
What is intense solar heating causes rising moist air at the equatorial low, leading to frequent condensation and heavy rainfall?
