Pressure
Under high pressure what is the air in the sky doing?
Sinking down
In a cold front, what do we expect the temperature to do after it passes over?
Drop / get cooler / get colder (cannot only say gets cold)
In a warm front, what do we expect the temperature to do after it passes over?
Rise / increase / warms up (cannot only say gets warm)
In a stationary front, what do we expect the temperature to do after it passes over?
Stay about the same
What causes global wind patterns?
The uneven heating of the Earth from the Sun
In high pressure what type of weather do you expect to see?
Happy weather - clear skies, sunny, less humid
What does the symbol for a cold front look like on a map?
Blue line with triangles/spikes
What does the symbol for a warm front look like on a map?
Red line with semicircles
What does the symbol for a stationary front look like on a map?
Alternating red and blue with alternating blue triangles and red semicircles on opposite sides
Winds carry _____ air away from the equator and _____ air towards the equator.
warm; cold
In low pressure what type of weather do you expect to see?
Lousy weather - cloudy, muggy, rainy
When a cold front is currently passing over what type of weather would you expect to see?
Thunderstorms
When a warm front is currently passing over what type of weather would you expect to see?
Light rain/drizzling
Rank based on speed of travel from slowest to fastest: warm front, cold front, stationary front
Stationary - Warm - Cold
Slowest Fastest
Winds spin counterclockwise in the northern hemisphere because
Coriolis effect / rotation of the Earth
Surface winds flow from _______ pressure to _______ pressure
High to low
Once a cold front has passed through an area, describe what type of weather you expect to see
Once a warm front has passed through an area, describe what type of weather you expect to see
Clear skies, warmer temp.
What does an occluded front look like on a weather map?
Purple line with alternating semi-circles and triangles facing the same direction
Why are there seasons?
Tilt of the Earth on it's axis, and it revolving around the sun
What direction does the wind travel in low pressure systems?
Counter-clockwise
What is happening to the air masses in a cold front?
The cold front runs into a warmer air mass, forcing it upward leading to the formation of thunderclouds
What is happening to the air masses in a warm front?
The warm air mass runs into a cooler air mass, rises over it and slowly pushes it
What is happening to the air masses in a stationary front?
Two air masses stop moving and a stationary front is formed at their boundary
Rainforests are found at ____________ latitude and deserts are most commonly found at __________ latitude
0 degrees (the equator); 30 degrees N or S
