Thunderstorms
These thunderstorms are caused by advancing cold fronts.
What are frontal thunderstorms?
This thunderstorm occurs when an air mass rises due to orographic lifting.
What is a mountain thunderstorm?
The calm center of a hurricane
What is the eye?
An extended period of low rainfall, usually caused by shifts in global wind patterns, allowing high-pressure systems to remain for weeks or months over continental areas.
What is a drought?
This thunderstorm is caused by extreme temperature differences between air above land and the air above the oceans.
What is a sea-breeze thunderstorm?
This violent, whirling column of air in contact with the ground forms when wind direction and speed suddenly change with height.
What is a tornado?
The strongest winds of a hurricane occur in this band surrounding the center.
What is the eyewall?
A temperature scale i which water freezes at 32 degrees and boils at 212 degrees.
What is the Farenheit scale?
This thunderstorm forms due to unequal heating of Earth's surface.
What is an air-mass thunderstorm?
This extremely powerful, self-sustaining thunderstorm is characterized by intense, rotating updrafts.
What is a supercell?
This large, rotating low-pressure storm gets its energy from the evaporation of warm ocean water and the release of heat.
What is a tropical cyclone?
An extended period of lower-than-normal temperatures caused by large, high-pressure systems of continental polar or arctic origin
What is a cold wave?
This branch channel of partially ionized air is formed between positive and negative regions of air.
What is a stepped leader?
This violent, damaging thunderstorm wind is concentrated in a local area.
What is a downburst?
This mound of ocean water is driven toward land by hurricane-force winds.
What is a storm surge?
An extended period of higher-than-normal temperatures caused by large, high-pressure systems that warm by compression and block cooler air masses
What is a heat wave?
This branched channel of positively charged particles rushes upwards to meet the stepped leader.
What is a return stroke?
This classifies tornadoes according to their wind speed on a scale ranging from EF0 to EF5.
What is the Enhanced Fujita Tornado Damage Scale?
This classifies hurricanes based on wind speed, which gives an idea of the potential for property damage.
What is the Saffir-Simpson Hurricane Wind Scale?
This estimates the heat loss from human skin caused by a combination of wind and cold air.
What is the wind-chill index?
