Predicting the weather
100
The boundary where air masses meet and do not easily mix well.
What is a front?
100
An air mass has these characteristics in common at any given height, causing it to be categorized as "one" mass.
What are similar temperature, humidity, and air pressure?
100
These form when lightening strikes sand or sandy soil.
What are fulgurites?
100
the cause of thunder
What is the rapid expansion of air (explosion) that comes from the intense heating (up to 30,000 degrees C) from lightening?
100
When is hurricane season for the East Coast of the United States?
What are August, September, and October?
200
4 main types of air masses and a description of each
What is Maritime Tropical (forms over ocean, humid, and warm); Maritime Polar (forms over ocean, humid, and cold); Continental Tropical (forms over land, dry, and warm); Continental Polar (forms over land, dry, and cold)?
200
Embedded within the Prevailing Westerlies are these tiny things that help push air masses along their paths.
What are Jet Streams?
200
A small violent disturbance in the atmosphere that is accompanied by heavy precipitation and frequent thunder and lightening.
What is a thunderstorm?
200
flooding, lightening, and wind
What are Thunderstorm factors that can cause damage?
200
lines on a weather map that show areas of similar pressure
What are isobars?
300
This type of air mass brings warm humid air to the southeastern United States.
What is Maritime Tropical?
300
When a rapidly moving cold air mass runs into a slow moving warm air mass?
What is a cold front?
300
2 names for the clouds that form Thunderstorms
What are cumulonimbus and thunderheads?
300
3 ways the Tornados differ from Hurricanes
What are size, life-span, land vs. water formation?
300
A "watch" vs. a "warning" with Hurricanes vs Tornados
What is a watch when a hurricane or tornado may hit a specific area? What is a warning when a hurricane is probably and almost certain in an area or a tornado has been sighted to have touched down?
400
The major wind belts over the continental United States that generally push air masses from west to east.
What are the Prevailing Westerlies?
400
When a cold and a warm air mass meet but neither one can move the other
What is a stationary front?
400
a definition of lightening
What are electrical charges that jump from cloud to cloud or cloud to ground (electrical spark)?
400
Tropical Storm, Hurricane, but this came first
What is a Tropical Disturbance?
400
Tools used to predict the weather (at least 5)
What are weather satellites, weather balloons, automated weather stations, computers, maps/ charts, simple observations?
500
These form with a L pressure inside and a H pressure outside. This one specifically forms in a counter-clockwise motion in the Northern Hemisphere.
What is a Cyclone?
500
This is the most complex weather situation, please name and describe it.
What is an Occluded Front? It is when a warm air mass is caught between 2 cooler air masses. The 2 cooler air masses meet underneath the warm air mass and push the warm air mass upward.
500
The Great Plains often get more Tornados because of these weather patterns
What is the warm. humid air mass moving up from the Gulf of Mexico meeting up with the cold, dry air moving downward from Canada?
500
Hurricane Formation
What is low-pressure area (Tropical Disturbance) forms over the ocean? As this air rises and cools it forms clouds. As more air is drawn into the system, bands of very high wind spiral inward toward the area of lowest pressure.
500
draw a symbol used to show an area with 20-30% cloud coverage, 9-14 mph winds from the south, 72 degrees F, and 1020 millibars of air pressure
