Chapter 10- Thunderstorms and Tornadoes Flashcards
The Fujita Intensity Scale (F-Scale) is applied to
Tornadoes
Prediction success and observation of sever thunderstorms and tones does by the national weather service is limited
Weather stations are widely spaced compared to the size of the storm
This type of clouds brings thunderstorms
Cumulonimbus clouds
At what time of day is an air-mass thunderstorm more likely to develop?
Mid-afternoon
The formation of tornadoes is associated with
Severe thunderstorms, cold fronts, middle latitude cyclones
Thunderstorms can be associated with these weather activities
Cyclones, hurricanes, tornadoes
Tornadoes most often move toward what direction?
North east
Thunderstorms and large cumulus clouds are characteristic of
Unstable air
A tornado is a small, very intense example of the
Cyclone
Which of the following statements is not true of tornadoes?
Usually occur along the warm front of a mid latitidue cyclone
Why do most tornadoes in the central U.S. Occur during the spring months?
Air mass contrasts are the greatest
Tornadoes and mid latitude cyclones are similar in that
Both are areas of low pressure
Why is very humid air near the surface a necessary ingredient for severe thunderstorms?
More latent near is available as energy.
Why is strong heating of the ground by the sun associated with thunderstorms?
Leads to greater instability
Why are thunderstorms most likely to occur in the afternoon and early evening?
Atmosphere is most unstable at that time
