This type of cloud is necessary for tornado formation.
What is a CUMULONIMBUS cloud; (A vortex will not form without the strong updraft of a thunderstorm cell.)
100
Is the atmospheric pressure in Houston higher, lower, or nearly equivalent to that of Chicago?
What is Nearly equivalent--They are very close to the same isobar, indicating nearly equal pressure.
100
They all begin the same way--with a current of rising air, otherwise known as _____________.
What is an UPDRAFT
100
This is the calmest part of a hurricane.
What is the EYE
100
This is a tornado that forms over water.
What is a WATERSPOUT
200
Both the BERGERON process and the COLLISION-COALESCENCE process explain precipitation, but they each begin with a different kind of cloud. With what kind of cloud does each theory begin?
What is BERGERON - cold COLLISION-COALESCENCE - warm
200
Is the atmospheric pressure in Houston higher, lower, or equivalent to that of Atlanta?
What is lower--Houston is 3 isobars from the L symbol, while Atlanta is 4 isobars away. This means Atlanta's pressure is higher.
200
Put the 5 stages of a thunderstorm cell IN ORDER: mature - dissipation - updraft - cumulus - downdraft
What is Updraft - Cumulus - Mature - Downdraft - Dissipation
200
Hurricanes are more properly called ___________ because of where they originate--always starting in the tropics.
What are TROPICAL CYCLONES
200
In hurricanes, most of the devastation comes from flooding. Winds push water in the direction of its motion, causing waves. Also, the low pressure of the eye causes the ocean to bulge upward. What is the name given for the waves + bulge?
What is STORM SURGE
300
List the 5 stages of a tornado in order. At which stage is the tornado most destructive?
What is whirl stage - organizing - mature - shrinking - decaying; The MATURE stage is the most destructive;
300
Is the occluded front nearer to San Francisco or Canada?
What is San Francisco--The occluded front has triangles and ovals on the same side!
300
In this stage of a thunderstorm, the water droplets and/or ice crystals in the cloud become too large, and it begins to rain. Name this stage.
What is MATURE stage
300
Hurricanes spin in opposite ____________ and opposite _____________.
What are DIRECTIONS and HEMISPHERES
300
This is the most common type of lightning, also known as sheet lightning because it lights up the sky in sheets.
What is CLOUD-to-CLOUD lightning
400
multiple choice: Lightning forms as a result of electrical charge imbalance. Where does that charge imbalance originate and why does it occur? A-It first forms in the cirrus cloud, and is due to water droplets or ice crystals rubbing against each other in glancing collisions. B-It is formed in the return stroke which is responsible for the majority of light and sound in a lightning bolt. C-It forms in the cumulus stage, where there is only an updraft and no precipitation. D-It is the result of several cells, each of which produces heavy rains for about 30 minutes or less. E-None of the above
What is (E) Choice A is *almost* correct; It forms in a CUMULONIMBUS cloud.
400
Will Atlanta or Indianapolis be in for some warmer weather soon?
What is Indy--The warm front has only ovals on it, and the ovals point in the direction of travel. SO...Indianapolis will get warmer weather soon. ---- Bonus extra 400--At the time this map was drawn, what city drawn on the map might be experiencing thunderstorms?
400
In this stage of a thunderstorm, as the air rises, water condenses onto cloud condensation nuclei, which actually heats the cloud condensation nuclei, making the current of rising air stronger. Name this stage.
What is CUMULUS Stage
400
These are lines of thunderstorm cells rotating around the eye, and spiraling slowly inward. What are these called?
What are RAIN BANDS
400
In a tornado, an updraft combined with a funnel of air which creates air whirling both around and up is known as _______.
What is a VORTEX
500
Fill in the blanks with these words: dew - drizzle - freezing rain - hail - sleet - snow -- ____________ starts out as a raindrop or an ice crystal blown back into the cloud by an upward gust of wind. ____ is formed as raindrops fall through a layer of cold air causing them to freeze. In this stage, ______, raindrops fall through a layer of air that is just at or slightly below the freezing point of rain.
What are... HAIL Sleet FReezing RAIN
500
What city probably experienced long rains followed by thunderstorms recently?
What is San Francisco--It is behind an occluded front. Since the weather described is that of an occluded front, S.F. might have just experienced such weather.
500
A thunderstorm cell is raining, and there is no updraft. In what stage is the thunderstorm cell?
What is DISSIPATION stage
500
In this module, Dr. Wile mentioned that hurricanes need 2 things to form. Name them:
What are *a warm ocean (to feed it warm, moist air) *a place where Coriolis effect is pronounced
500
In a lightning storm, a charge imbalance in a cloud causes charges to build up on the ground. Then positive charges on the ground attract some negative charges from the cloud. This forms a _____________.
What is STEPPED LEADER.
