100
This is the study of atmospheric phenomenon
What is meterology
100
This effect, along with the heat imbalance on Earth, creates the three major global wind systems
What is the Coriolis effect
100
This is the most common weather instrument
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 toward the equator in a westerly direction
What are 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
This is the device used to measure relative humidity
What is a hygrometer
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 applies when an air mass starts to acquire some of the characteristics of the new surface beneath it
What is an air mass modification
500
These are narrow bands of fast, high-altitude, westerly winds
What is the jet stream
500
This device is used by the ASOS to measure the height of cloud layers and estimates the amount of sky covered by clouds
What is a celiometer
500
You can tell how fast the wind is blowing in an area by noting how closely these are spaced
What are isobars
500
Global wind system flow on either side of the equator are this
What is opposite of each other
