Exam #3 Flashcards
Your instructor said that the bad thing about teaching a course about natural disasters is that there are always new natural disasters, including the one he mentioned at the start of last Wednesday’s lecture. What kind of natural disaster was it?
You Answered
A) An asteroid or comet impact.
B) An earthquake.
C) A volcanic eruption.
D) A severe storm.
B) An earthquake.
A volume or parcel of air that begins rising through the atmosphere because it is passing over a mountain range is experiencing what type of lifting mechanism?
A) Convective lifting.
B) Convergent lifting.
C) Frontal lifting.
D) Orographic lifting.
D) Orographic lifting.
What type of lifting mechanism is in operation between masses of cold and warm air rotating around the central low of a cyclone?
A) Convective lifting.
B) Convergent lifting.
C) Frontal lifting.
D) Orographic lifting.
C) Frontal lifting.
What type of lifting mechanism operates as air from the outside of a tropical cyclone is pulled into the low pressure of the interior of the tropical cyclone?
A) Convective lifting.
B) Convergent lifting.
C) Frontal lifting.
D) Orographic lifting.
B) Convergent lifting.
The location of a front on a weather map is where the frontal boundary is on the land surface. Precipitation (rain or snow) can happen that greatest distance from the location of this type of front:
A) A cold front.
B) An occluded front.
C) A warm front.
C) A warm front.
What type of front did your instructor say would produce the most precipitation (rain or snow)?
A) A cold front.
B) An occluded front.
C) A warm front.
B) An occluded front.
______________ is another name for a mid-latitude cyclone.
A) An exratropical cyclone.
B) A geostrophic wid.
C) A tropical cyclone.
A) An exratropical cyclone. (Because the temperate zone is outside the tropics)
A mid-latitude cyclone would move from _____________ across Kansas.
A) East to west.
B) North to south.
C) South to north.
D) West to east.
D) West to east.
A mid-latitude cyclone over Kansas would rotate ___________.
A) Clockwise.
B) Counterclockwise.
C) A mid-latitude cyclone over Kansas would not rotate.
B) Counterclockwise.
What is convective lifting
Air lifting by convection. Convection is when solar energy passes through the atmosphere and heats the surface, where the air becomes less dense than the air around it, making it rise
how a cyclone would move across Australia and how it rotate in the southern hemisphere. Because the temperate zone is outside the tropics.
In the southern hemisphere these tropical storms are called cyclones and rotate in a clockwise direction
Where on Earth would you NOT expect a tropical cyclone to develop because of the lack of a Coriolis or Momentum Effect?
A) In the Eastern Pacific Ocean.
B) In the South Atlantic Ocean.
C) In the Indian Ocean.
D) Along the Equator.
D) Along the Equator. Because of the lack of a Coriolis or Momentum Effect along the Equator because of the lack of a Coriolis or Momentum Effect along the Equator.
Which of the following organizations compose the annual list of names for tropical storms and tropical cyclones in the various ocean basins of the world?
A) The U. S. National Weather Service.
B) The World Meteorological Organization.
C) The United Kingdom Meteorological Office.
D) The National Oceanographic and Atmospheric Administration.
B) The World Meteorological Organization. The WMO devises the lists from first names (alternating between male and female first names) common it that part of the world
Which of these common first names in the United States would NOT be used in the annual list of Atlantic Basin hurricane names?
A) Arlene.
B) Harold.
C) Ophelia.
D) Zach.
D) Zach. First names starting with Q, U, X, Y and Z are not used in the list of 21 named storms that the WMO composes for the Atlantic Basin
These three first names were used in the 2023 list of tropical storm names for the Atlantic Basin. None of these names were retired and will be used again when this list is next used in 2029
The Saffir-Simpson Scale for tropical cyclones is a measure of _____________.
A) Sustained wind speed.
B) Storm surge height.
C) Peak wind speed.
D) All of the above.
A) Sustained wind speed. The full name of the Saffir Simpson Scale is the Saffir- Simpson Hurricane Wind Scale (SSHWS)
A tropical cyclone of ____________ or greater on the Saffir-Simpson Scale is considered to be a major tropical cyclone.
A) Category 1.
B) Category 2.
C) Category 3.
D) Category 4.
E) Category 5.
C) Category 3. also know that there is some discussion of extending the Saffir-Simpson Scale (currently ranging
from Category 1 to Category 5) to Category 6 to account
for an increasing number of what are now called very
high Category 5 tropical cyclones in our time of warming
ocean surface temperatures
Where are sustained wind speeds heighest in a tropical cyclone?
A) In the center of the eye.
B) Along the eyewall.
C) Along the outer margin of the tropical cyclone.
D) Sustained wind speeds are constant throughout a tropical cyclone.
B) Along the eyewall.
