100
Define "meteorology".
What is "the study of atmospheric phenomenon?"
100
Caused by Earth's rotation, this deflects moving air clockwise in the northern hemisphere.
What is the Coriolis effect?
100
Cold, dense air that displaces warm air, forcing the warm air up.
What is a cold front?
100
An instrument that measures air pressure.
What is a barometer?
100
Lines of equal values on a weather map
What are isopleths?
200
Compare/contrast weather vs climate.
What is weather is the current state of the atmosphere, while climate is the long-term trends in the atmosphere?
200
It's the wind system between the equator and 30 degrees latitude.
What is the trade winds?
200
Advancing warm air that displaces cold air.
What is a warm front?
200
An instrument that measures wind speed and direction.
What is an anemometer?
200
Lines of equal pressure on a weather map
What are isobars?
300
A large parcel of air that takes on the characteristics of the area over which it forms.
What is an air mass?
300
It's the wind system between 30 and 60 degrees latitude, and is responsible for the movement of weather systems in North America.
What are the prevailing westerlies?
300
Two air masses that meet and do not advance.
What is a stationary front?
300
A balloon-borne package of sensors that gathers upper-level wind data
What is a radiosonde?
300
All forecasts are more reliable in this time frame.
What is the short term?
400
This type of air mass originates over oceans.
What is a maritime air mass?
400
It's the wind system between 60 degrees latitude and the poles.
What are polar easterlies?
400
Name two of the three characteristics of a high pressure system.
What are sinking air, clockwise rotation, and air flows away from the center?
400
Meteorologists use this tool, which measures changes in wave frequency, to locate areas of precipitation and associated wind speeds.
What is Doppler radar?
400
Type of weather typically associated with a high pressure system
What is fair (clear) weather?
500
When an air mass travels over land or water that has different characteristics from those of its source region, it undergoes this.
What is air mass modification?
500
This is a narrow band of fast, high-altitude westerly wind flow found at the boundaries between 30 and 60 degrees latitude.
What is the jet stream?
500
Name two of the three characteristics of a low pressure system.
What are rising air, counter-clockwise rotation, and air flows toward the center?
500
Meteorologists use this tool, which measures differences in thermal energy, to map cloud cover or surface temperatures.
What is infrared imagery?
500
Type of weather typically associated with a low pressure system
What are clouds and precipitation?
