What is the Coriolis effect

100

This instrument measures temperature

What is a thermometer

100
This is a record of weather data for a particular site at a particular time
What is a station model
100
This is a narrow region separating two air masses of different densities
What is a front
200
This is the current state of the atmosphere
What is weather
200

This wind system occurs at 30 degrees north and south latitude, where air sinks, warms, and moves from the north east toward the equator in a westerly direction

What are the northeast and southeast trades or the trade winds

200

This weather instrument uses mercury to measure air pressure

What is a barometer

200
To plot data nationwide or globally, meteorologists use these lines that connect points of equal or constant values
What is isopleths
200
At the moment, this is the instrument of choice for gathering upper-level data, and is borne aloft using a weather balloon
What is a radiosonde
300
This is the term for long-term variations in weather for a particular area
What is climate
300

This wind system flows between 30 and 60 degrees north and south latitude in a circular pattern opposite that of the trade winds

What are the prevailing westerlies

300
This device measures wind speed
What is an anemometer
300
These are forecasts that rely on extremely large amounts of data, such as national forecasts
What are digital forecasts
300
This is the change in wave frequency that occurs in energy, such as sound or light, as that energy moves toward or away from an observer
What is the Doppler effect
400
This term refers to a large body of air that takes on the characteristics of the area over which it forms
What is an air mass
400
This wind system lies between 60 degrees latitude and the poles
What are the polar easterlies
400

What do hygrometer and psychometers measure?

What is relative humidity

400
Regardless of the forecasting method used, this is what all long-term forecasts become
What is less reliable
400
In surface low-pressure systems, the air does this
What is rise
500

This terms for the point where two different air masses collide

What is a front

500
These are narrow bands of fast, high-altitude, westerly winds
What is the jet stream
500

What is the unit of measurement for the aneroid barometer outside the school

What is inch mercury

500
You can tell how fast the wind is blowing in an area by noting how closely these are spaced
