This is a large body of circulating air with high pressure at its center and lower pressure outside of the system.
What is a low pressure system
100
This may have warm temperatures, moisture, and rising air which may be supplied by a low pressure system.
What is a Thunderstorm
100
This report describes a set of weather measurements made on the Earth's surface.
What is a surface report.
100
This is the amount of water vapor in the air.
What is humidity
200
Created when air moves from areas of high pressure to areas of low pressure.
What is wind
200
This is a large body of air that has uniform temperature, humidity, and pressure.
What is an air mass.
200
This is a violent, whirling column of air in contact with the ground.
What is a tornado.
200
This shows which areas are warm and which are cold.
What are isotherms.
200
These are the forms of precipitation.
What are rain, sleet , ice , and snow

What is an upper air report.
300
These are lines that connect all places on a map where pressure has the same value.
What are isobars?
400
The amount of water vapor in the air compared to the maximum amount possible.
What is relative humidity
400
This is what happens at the frontal border of the air mass.
What is precipitation
400
This form of severe weather can have winds in excess of 300mph (450 k/hr).
What is a tornado
400
This is 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.
What is Doppler Radar
400
These are detailed programs that solve a set of complex mathematical formulas to predict weather for a particular time and place.
What are computer models?
500
The temperature at which air is saturated and condensation can occur.
What is the dew point
500
These are the air mass classifications.
What is polar maritime, polar continental, tropical maritime, and tropical continental.
500
These are the stages of a thunderstorm.
What is cumulus, mature, and dissipating
