Meteorology
Weather Terms
Tornado
Hurricane
100
The scale that measures the strength of tornadoes based upon wind speed.
What is The Fujita Scale
100
A whirling mass of warm, moist air that generally brings stormy weather with strong winds. When viewed from above, winds spiral in a counterclockwise rotation in the Northern Hemisphere.
What is a low pressure system and is represented as a big, red L.
100
The force of the air on a surface. It is measured in millibars. It is equal to the weight of a vertical column of air divided by the area of the base of the column.
What is air pressure
100
At what temperature are tornado's not going to develop?
What is 50 degrees fahrenheit or converted is 10 degrees celcius
100
What is the distinctive feature seen on many hurricanes and are unique to hurricanes, located in the center of a hurricane?
What is the EYE
200
Tornado winds that reach 158-206 m.p.h. that cause severe damage. Trains may be overturned and cars lifted off the ground.
What is F3 Tornado
200
A whirling mass of cool, dry air that generally brings fair weather and light winds. When viewed from above, winds spiral out in a clockwise rotation in the Northern Hemisphere. These bring sunny skies.
What is H a high pressure system.
200
A unit of speed equal to 1.51 miles per hour
What is a knot
200
What is a tornado that forms over water?
What is Waterdevil
200
The lifespan of a tornado is how long?
What is as brief as a day or as long as several weeks.
300
A system for reporting wind speeds that is based on the visible effects of wind on land sea such as white caps.
What is Beaufort Wind Scale
300
The highest pressure in a high and lowest pressure in low at sea level.
What is central atmospheric pressure
300
Water that falls to the earth's surface. Types if these include rain, sleet, snow hail and mist.
What is precipitation
300
The information given by meterologist that a tornado is either on the ground or has been detected by Doppler radar. Seek shelter immediately! is a watch or a warning status?
What is Tornado Warning
300
Hurricanes are rated for their intensity by what characteristic and what is the scale called?
What is the wind speed and is called the Saffir-Simpson Scale. Scale ranges from F1 to F5.
400
This scale classifys hurricanes based on their intensity and used to predict how damaging the hrricane will be. The scale is of 1 as minimal and 5 as catastrophic.
What is Saffir-Simpson Scale
400
A large body of air whose properties of temperature and moisture content (humidity), at any given altitude, are fairly similar in any horizontal direction. Can control the weather for a relatively long time period: from a period of days, to months.
What is an Air Mass
400
The boundary between an advancing mass of warm air and mass of colder air. On the weather map it is indicated by a row of semicircles. These are associated with overcast skies and gentle showers.
What is warm front
400
What hours of the day are tornado's most likely to hit?
What is Tornadoes are most likely to occur between 3 p.m. and 9 p.m.
400
What are the three stages of a hurricanes life?
What is (1) Tropical Depression (2) Tropical Storm to (3) Hurricane.
500
A drop in this usually indicates the approach of bad weather, such as a hurricane or a tornado.
What is Atmospheric Pressure
500
A boundary between two air masses, one cold and the other warm, moving so that the colder air replaces the warmer air. It is represented as a blue line with the teeth pointing toward the direction on movement.
What is cold front
500
The type of cloud that is the highest cloud in the atmosphere.
What is a cirrus cloud
500
The tornado measurement scale that measures Tornado Intensity is measured as an EF 1 through EF 5. What does the EF stand for?
What is Enhanced, Operational,Fujita Scale
500
What are three of the five conditions does a hurricane need to develop?
What is (1) warm ocean water (80 degrees F) (2) winds converging from different directions forcing air upwardly (3) Winds flow outward above the storm (4) humid air rises making the clouds of the storm (5) winds outside the hurricane blow and steer the storm
