Miscellaneous Weather
100
Raindrops or ice crystals that are continually blown back in the cloud by an upward gust of wind, frozen into larger than normal size ice crystals that eventually fall to the earth because of there weight.
What is Hail?
100
The stage which water droplet or ice crystals in the cloud become too large for the updraft to support at that point it begins to rain leading to heavy rain, thunder, lightening, strong winds, and sometimes hail.
What is the mature stage?
100
When an updraft of air forming a cumulonimbus cloud begins being hit by winds blowing in a difference direction at higher altitudes.
What is the whirl stage of a tornado?
100
A transmitter that emits radio waves at a rate of several hundred waves per second. When those waves encounter an object they bounce off the signal and head back town the receiver.
What is RADAR (radio detection and ranging)?
100
The closeness of the negative charges in the cloud forces the positive charges up (from the ground, tree, etc...)
What is cloud to ground lightning?
200
Raindrops falling through layers of cold air, that freezes as ice pellets.
What is sleet?
200
The stage of a thunderstorm where condensation tens to heat up the cloud-condensation nuclei causing the updraft to grow strong pulling up more and more warm moist air.
What is the cumulus stage?
200
Winds that cause air to begin rotating horizontally combined with the updraft causes a funnel of air to form.
What is the vortex stage of a tornado?
200
Take data continuously all over the world giving us very accurate data about our earth. Give us the best evidence yet that global warming is not happening.
What is a weather satellite?
200
Lightning that occurs between two or more separate clouds. When positive charges concentrate together trying to get close to the negatively charged cloud as possible.
What is cloud to cloud (sheet lightening)?
300
Precipitation that usually forms in a stratus cloud and consist of tiny droplets of water.
What is drizzle?
300
A current of rising air usually caused by a cold from moving into a warm front.
What is an updraft?
300
When the funnel of air touches the ground forming a solid base and the upward whiling motion of the vortex sucks debris up into the funnel.
What is the mature stage of a tornado?
300
Black thin lines on a weather map joining together places of equal atmospheric pressure.
What is an isobar?
300
When the negative charge gets closer to the ground the positive build up more force, eventually overcoming the insulating properties of air and rushing up to meet the negative charges that are moving down. (It is also responsible for most of the light and sound of lightening).
What is the return strike?
400
The theory that each cloud contains many water droplets that have condensed on cloud-condensation nuclei.
\
What is the Collison-Coalescense Process?
400
Downward rushes of air that can be quite severe in a concentrated area bringing winds to to 170 mpg.
What are downdrafts?
400
An area of low pressure system that begins over warm water as a thunderstorm and as updrafts begin iced with the Coriolis effect it causes a vortex of whirling winds to form bringing with it heavy rains, winds over 155 mph.
What is a hurricane?
400
A PURPLE weather front line on a weather map with triangles and circles on the same side of the line.
What is an occluded front?
400
The transfer of charge that occurs when the bottom of the cloud starts building up negative charges which in turn attracts the positive charge on the ground causing a jerky movement of the negative charge toward the earth.
What is a stepped leader?
500
The process that deals with how rain is formed in COLD clouds.
What is the Bergeron Process?
500
The stage of a thunderstorm which the downward drafts take over the upward drafts and the rain gets lighter and lighter, and the downdrafts get less and less powerful eventually leading to the storm running its coarse and the rain stops. 
What is the dissipation stage?
500
Low pressure of the eye causes the ocean beneath the hurricane to bulge upward, this combined with high winds push water along causing huge waves causing ocean to rise many feet higher than it otherwise would. 
What is a storm surge?
500
A PURPLE weather front line on a weather map with triangles and circles on the opposite side of the line.
What is a stationary front?
500
A substance that does not conduct electricity well, think air.
What is an insulator?
