exam 4 Fall 23 prep

Why will you hardly find any hurricanes on or very near the equator (less than 5º latitude)?

• Surface high pressure systems found in that latitude range prevent the development of tropical storms.

• Friction forces in this latitude range are too strong to allow the storm to rotate properly

• Tropical disturbances that form in this area are obstructed by Rossby waves and die out quickly.

• Sea surface temperatures in this area are too cold to support hurricane formation

• Coriolis force in this area is too weak for hurricanes to form.

17.  When higher levels of ¹⁸O are found in ocean sediment cores, this indicates that the earth was experiencing a     period in history.

• colder

• warmer

• wetter

• drier

17.  In the United States, tornadoes can occur during any time of the year, but the vast majority occur in the            because of interaction between    ___ .

• fall; mP and cP air masses

• fall; mP and mT air masses

• spring; cP and cT air masses

• spring; mP and mT air masses

• spring; cP and mT air masses

Biological indicators can be used as proxy data for specific climate conditions. Which is the correct proxy /climate variable relationship.

• coal deposits for precipitation

• pollen for solar angles

• diatoms for drought

• trees for ocean temperature

Which of the following will stop hurricane development?

• warm ocean waters (at least 80ºF)

• Coriolis force to get the storm to spin

• strong wind shear to blow the tops of the clouds over

• moisture supply through evaporation of ocean water

Which of the following is a predicted result of future climate change?

• Sea levels will remain the same

• All areas of the globe will get cooler, and most will cool by 1-2ºF

• Ecosystems will have to relocate to find growing conditions more suitable for them

• Hurricanes and tropical storms will be less intense

• Severe weather and droughts will be less common

The pathway of charged particles that extends downward from the bottom of thunderstorm cloud is called:

• a flash path

• a strike path

• a streamer

• a step leader

The climate of Wisconsin is best described as

• tropical

• semi-arid, dry

• mesothermal

• microthermal

• polar

Tornadoes are ranked in terms of wind damage using the      scale

• Enhanced Fujita

• Saffir-Simpson

• Edwards-Fouts

Why is the general direction of hurricane movement across the Atlantic from east to west, while the general direction of mid-latitude cyclones is from west to east?

• because hurricanes are pushed by the westerlies

•   because the semi-permanent low pressure systems only generate hurricanes during the summer months

• because the hurricanes are pushed by the trade winds

• because mid-latitude cyclones are only formed in the Atlantic Ocean
