100
Short term variants in atmospheric phenomena that interact and affect the environment.
What is weather?
100
This results in fluids and objects moving in a curved lined.
What is the Coriolis effect?
100
Where two air masses collide.
What is a front?
100
Instrument that measures temperature.
What is a thermometer?
100
The change in pitch due to the relative motion of a wave.
What is the Doppler Effect?
200
The long term average variations of weather.
What is climate?
200
Wind zones between 60 degrees north or south and the poles.
What are the polar easterlies?
200
Identified by a blue line with triangles.
What is a cold front?
200
This measures relative humidity.
What is a hygrometer?
200
Lines of equal temperature.
What are isotherms?
300
The reason that polar and tropical regions maintain fairly constant average temperatures.
What is the continual movement of air and water moving the heat energy? (Also acceptable is Convection)
300
Wind System on Earth that is between 30degrees and 60 degrees north or south.
What are the prevailing westerlies?
300
This pressure system is associated with clouds and rain.
What is low pressure?
300
Lines on a map that connect points of equal pressure.
What are isobars?
300
Created by applying physical principles of mathematics.
What is a digital forecast?
400
A large volume of air that has the same characteristics as the area from which is was created.
What is an air mass?
400
A narrow band of fast wind.
What is a jet stream?
400
When a cold air mass moves rapidly that it forces warm air upwards and "catches up" to the prior cold front.
What is an occluded front?
400
An anemometer measures these two things.
What is wind SPEED and DIRECTION? DAILY DOUBLE
400
This detects difference in thermal energy.
What is infrared imagery?
500
The area over which an air mass forms.
What is a source region? DAiLY DOUBLE
500
This is an easterly wind that lies between the equator and 30 degrees north or south.
What are Trade Winds?
500
The type of cloud cover associated with a stationary front. In particular on the warm air side.
What is partially cloudy skies?
500
A record of weather data for a particular site at a particular time.
What is the station model?
500
The exchange of heat or moisture with the surface over which an air mass travels.
What is air mass modification?
