Meteorology Unit Test (Chapters 18-20)

Which of the following is NOT a characteristic of the eye of

a hurricane?

• has the storm's strongest winds

• is at the storm's center

• has no precipitation

• is warm because of descending air

A hurricane’s energy comes from

• condensation of large amounts of water vapor

• lightning striking as the storm forms

• the movement of continental tropical air masses

• the action of waves in warm ocean waters

Which of the following is NOT generally associated with a

thunderstorm?

• tornado

• lightning

• warm air

• cold front

A violent windstorm that forms a rotating column of air

called a vortex is a

• hurricane

• thunderstorm

• nor'easter

• tornado

What forms when a cold front overtakes a warm front?

• a warm front

• an occluded front

• a cold front

• a stationary front

What happens along a stationary front?

• Cold air rises over warm air

• The flow of air is neither toward the warm air mass nor toward the cold air mass

• Air moves so rapidly upward that hurricanes form

• Wind stops completely

Which of the following characteristics is NOT true of cold

fronts?

• Violent weather such as thunderstorms occur along them

• The temperature drops as they pass

• Clear weather usually follows them

• They move more slowly than warm fronts

Air masses are classified according to the

• direction in which they move

• speed of their movement

• surface over which they form

• temperature of their air at a certain time

A warm front forms when

• cold air moves up over warmer air

• a warm air mass meets another air mass of the same temperature

• warm air glides up over colder air

• the temperature in a warm air mass increases

What forms at the boundary between two different air

masses of different properties?

• a temperature inversion

• a front

• a hurricane eyewall

• a storm surge
