100
This forms when air remains stationary or moves slowly over a uniform region, taking on the characteristic temperature and humidity of that region.
AIR MASS
100
These usually produce short-lived storms.
Cold Front
100
Measures temperature in a given region
Thermometer
100
Scientists use this to convey information on a weather map.
Computers
100
Lines that connect points of equal temperature.
Isotherms
200
The four main types of air masses
polar, tropical, continental, and maritime.
200
These usually produce precipitation over a large area.
Warm Front
200
Measures atmospheric pressure in a given region.
Barometer
200
Meteorologists have tried to control.
Precipitation, Hurricanes, and Lightning
200
Lines that connect points of equal atmospheric pressure.
Isobars
300
This is a warm and wet Air Mass
Tropical Maritime Air Mass
300
A midlatitude cyclone forms along this front
Stationary Front
300
Measures wind velocity
Anemometer
300
A system that uses reflected radio waves to determine the velocity and location of objects
Radar
300
The weather man is called this.
Meteorolgist
400
This is a Cold and Dry Air Mass
Polar Continental Air Mass
400
These are caused by the interaction of air masses that have different properties.
thunderstorms and Tornadoes
400
Determines the direction of the wind.
Wind Vane
400
A cluster of Symbols indicating weather conditions.
Station Model
400
The most researched method for producing rain.
Cloud Seeding
500
This is a Wet and Cold Air Mass
Maritime Polar Air Mass
500
This develops when warm, moist air over the ocean rises rapidly.
Hurricane
500
Instrument that is measures relative humidity in the upper atmosphere. It is carried up by a balloon that blows up when it is too high.
