A balloon released into the atmosphere that carries a package of instruments to record data about temperature, air pressure, and humidity.
weather balloon
The lowest layer of Earth's atmosphere, where weather occurs.
troposphere
a storm with thunder, lightning, heavy rains and strong winds; usually occur in thunderheads or at a cold front
thunderstorm
warm front
A large body of air where temperature, moisture, and pressure content are constant throughout.
Indicates weather conditions at a specific location, using a combination of symbols
station model
2nd layer of atmosphere; extends from 10 to 30 miles up; location of ozone layer; absorbs 95% of Ultraviolet radiation; temperature increases with altitude increase.
stratosphere
A large, severe storm that forms over tropical oceans, has winds of at least 120 km/h, and loses power when it reaches land.
Hurricane
When a cold air mass overtakes a warm air mass
cold front
The boundary between air masses of different densities and usually different temperatures
front
a specialized type of radar that can detect precipitation as well as the movement of small particles, which can be used to approximate wind speed
doppler radar
3rd layer of the atmosphere above the stratosphere and below thermosphere
Mesosphere
Violent, whirling windstorm in the shape of a cyclone that crosses land in a narrow path and can result from wind shears inside a thunderhead.
Tornado
when cold and warm air masses are up against one another and neither one is pushing against the other
stationary front
What is your favorite type of storm?
________
A device that measures air pressure.
barometer
The uppermost layer of the atmosphere, in which temperature increases as altitude increases; Space Shuttle orbits here.
Thermosphere
a region of low pressure with counter-clockwise wind rotation that develops into a hurricane or tropical storm
Tropical depression
__________ air moves up in the atmosphere.
Warm
This type of air mass is cool and wet
polar maritime
This tool is used to measure wind speed and direction
anemometer
Outer layer of the atmospheres past the thermosphere
exosphere
This type of air, when pushed up into the atmosphere, can result in a thunderstorm.
warm and humid
What type of front often leads to violent and quick storms?
cold front
The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temperature
relative humidity
