100
This device is used to measure atmospheric pressure
What is a barometer.
100
What are global winds?
winds that blow in a predictable pattern over long distances.
100
Rain, hail, sleet, and snow are forms of...
Precipitation!
100
What causes most severe weather?
When the front of an air mass collides with another air mass (usually when cold meets warm)
100
Name two ways we forecast the weather.
Doppler Radar, weather balloons, satellites
200
Name two factors that affect air temperature. Name all for extra 100 points
There are four: water vapor; temperature; volume; and altitude.
200
What does San Diego tend to be warmer than Seattle?
The rays of sunlight hit Earth at different angles.
200
The average weather condition of a place is called
climate
200
before it touches the ground, what do we call a tornado?
a funnel cloud
200
Who studies the atmosphere?
A meteorologist, of course!! They study the weather as well.
300
The parameter on an plane measures 210 mm. If the next reading showed a measurement of 400 mm, has the plane increased or decreased in altitude?
The altitude has decreased.
300
Explain the convection in a Land Breeze (please give details)
because land cools quicker it is cooler and has higher pressure than the ocean. This causes the wind to blow from land to the sea.
300
If we threw a bottle into the ocean, we have a predictable area that it would travel to. Why is that?
The ocean currents of the world move in a predictable way.
300
What two things do thunderstorms need to be created?
A warm front and cold front!
300
How does air move in a low pressure system?
Air moves towards the center of the low pressure creating a counterclockwise pattern
400
What happens to air pressure when air is cooled?
The air pressure increases.
400
What is the reason for the Sea and Land Breeze?
The fact that land heats and cools faster than the ocean does.
400
What happens to wind during an El Nino year?
The wind will blow continuously from West to East (from the ocean to land)
400
Why are tornadoes severe in Tornado Alley?
The cold air mass from Canada meets with the warm air from the Gulf of Mexico. When a warm and cold air mass meet, it's never good!
400
What type of weather do Low Pressure systems bring with them?
They bring warm, humid stormy weather
