Name the type of precipitation that requires an updraft to form.
What is Hail?
Lightning forms in only what type of clouds.
What is cumulonimbus cloud.
When the funnel of air touches the ground it is in what stage of a tornado?
What is the organizing stage?
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)?
Lightning causes what by heating up the air through which it passes. That heat generates a wave that we detect as sound.
What is thunder?
The temperature at which water vapor condenses out of the air onto ground-level surfaces is called what?
What is dew point?
What is it called when the negative charges at the bottom of the cloud attract the positive charges in the ground, causing a jerky movement of negative charges toward the earth.
What is a stepped leader?
What differentiates all of the classifications of potential hurricanes?
What is wind speed?
Takes 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?
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)?
Name the two factors that effect the dew point.
What is humidity and pressure?
A current of rising air, usually caused by a cold front moving into a warm front, is called what?
What is an updraft?
An area of low pressure that originally formed the vortex that lead to a hurricane. Typically 10 miles or so in diameter.
What is the eye of the hurricane?
Black thin lines on a weather map joining together places of equal atmospheric pressure.
What is an isobar?
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?
The theory that each cloud contains many water droplets that have condensed on cloud-condensation nuclei.
What is the Collison-Coalescense Process?
Thunderstorms cells usually last much less than 30 minutes, what reason would they last longer than 30 minutes?
What is multiple storm cells?
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?
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?
What two things are needed in order for a hurricane to form?
What is warm, moist air from the ocean and a place where the Coriolis effect is most pronounced?
The process that deals with how rain is formed in COLD clouds and therefore starts out as snow and melts into rain as it reaches warmer air?
What is the Bergeron Process?
The stage of a thunderstorm where the entire area is full of only downdrafts, causing the rain to become lighter and lighter.
What is the dissipation stage?
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?
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?
A substance that does not conduct electricity well, think air.
What is an insulator?
