Air Masses
An air mass has 3 uniform characteristics. What are they?
Temperature, Humidity, and Air Pressure
What weather is created when a cold front pushes warm air upwards?
Thunderstorms/ Rain
What are the types of convection cells?
Hadley, Ferrel, and Polar
What is the primary effect of ocean currents on global climate?
They transport heat
Which global wind pattern blows east to west between the equator and 30 degree latitude and used to be used for merchant trade?
Trade Winds
How do air masses move relative to air pressure?
From high-pressure to low-pressure areas
What type of front occurs when warm air moves over cold air?
A warm front
What is the Coriolis effect?
The curving of moving air due to Earth's rotation
How do ocean currents affect coastal climates?
They moderate temperatures and influence precipitation patterns.
What is the primary cause of the global winds?
Uneven heating of the Earth
What air mass is characterized by warm, humid air?
Maritime Tropical (mT)
What type of air mass is associates with hot, dry weather?
Continental Tropical (cT)
How does the Hadley Cell influence climate?
Creates tropical rainforests near the equator
How does the Gulf Stream affect European climate?
It brings warm water from the equator making the climate milder.
Describe the Doldrums.
A calm area with little to no wind.
What type of air mass is associated with hot, dry weather?
Continental Tropical (cT)
What happens in an occluded front?
A cold front overtakes a warm front
How does the Coriolis effect influence global wind patterns differently in the Northern and Southern hemispheres?
Winds curve right in the north and left in the south
True or False: The Global Conveyor Belt circulation system is when warm water sinks at the poles while cold water rises at the equator.
False- cold water sinks while warm water rises
How do westerlies influence weather patterns in North America?
Move weather systems from west to east across the continent.
What is the primary characteristic of a maritime polar air mass?
Cold and humid
What would likely occur when a maritime tropical air mass meets a continental polar air mass?
Severe thunderstorms
Ethen Is not sigma
It moves in the opposite direction of both cells
True or False: If you have warm ocean water with rising air creating low pressure it would be favorable conditions for hurricane formation.
True
What role do polar easterlies play in the global climate?
They bring cold air from the poles toward lower latitudes.
