Things You Need To Know
Facts/Short Answer
100
State of the atmosphere at a specific time and place, determined by factors including air pressure, amount of moisture in the air, temperature, wind, and precipitation
Weather
100
A stratus cloud that forms when air is cooled to its dew point near the ground.
Fog
100
Violent, whirling wind storm that crosses land in a narrow path and can result from wind shears inside a thunderhead.
Tornado
100
Form layers at low altitudes and associated with fair weather, rain, or snow.
Stratus Cloud
100
Bring long, steady, rain or snowfall (type of cloud)
Nimbostratus
200
Amount of water vapor held in the air.
Humidity
200
Water falling from clouds- Including rain, snow, sleet, or hail- whose form is determined by air temperature.
Precipitation
200
Karge, severe storm that forms over tropical oceans, has winds of at least 120 km/h, and loses power when it reaches land.
Hurricane
200
Masses of puffy, white, clouds with flat bases. They can be associated with fair weather and thunderstorms.
Cumulus Clouds
200
Difference in wind speed and wind direction.
Wind Sheer
300
Measure of the amount of moisture held in the air compare with the amount it can hold at a given temperature.
Relative Humidity
300
Boundary between 2 air masses with different air temperatures, density, or moisture can be cold, warm, occluded, or stationary.
Front
300
Winter storm that lasts at least 3 hours with temperatures of -12°C or below, poor visibility, and winds of at least 51 km/h.
Blizzard
300
Appear curly and are high, thin, white, feathery, and made of ice crystals. They are associated with fair weather.
Cirrus Clouds
300
What is the difference between a cold front and a warm front?
Cold fronts have high pressure and heavy air that sinks. Brings fair weather because the cold air sinks. Warm fronts have low pressure and light air that rises. Brings cloudy weather because warm air rises, condensation forms, and clouds are made.
400
Temperature at which air is saturated and condensation forms.
Dew Point
400
Studies weather and uses information from Doppler radar, weather satellites, computers, and other instruments to make weather maps and provide forecasts.
Meteorologist
400
Line drawn on a weather map that connect points having equal temperature.
Isotherm
400
Clouds associated with rain or snow have the word _____ attached to them.
Nimbus
400
Why don't hurricanes form in the Earth's polar regions?
Hurricanes don't form in the Earth's polar regions. This is because hurricanes need warm air and water to generate power. (They form in the Atlantic Ocean; Typhoons form in the Pacific Ocean; and Cyclones form in the Indian Ocean)
500
Large body of air that has the same characteristics of temperature and moisture content as the part of Earth's surface over which it formed.
Air Mass
500
Indicates weather conditions at a specific location, using a combination of symbols on a map.
Station Model
500
Line drawn on a weather map that connect points having equal air pressure
Isobar
500
Thunderstorm clouds.
Cumulonimbus
500
How can wind speed and wind direction be measured? Give one example of each.
Wind speed can be measured by an anemometer. Wind direction can be measured by a wind sock or a wind vane.
