How do hurricanes differ from middle-latitude cyclones?
A)Hurricanes are cold-core lows, while middle-latitude cyclones are warm-core lows
B)Hurricanes derive their energy from horizontal temperature contrasts, while middle-latitude cyclones derive energy from latent heat.
C)Hurricanes have no fronts and are smaller, while middle-latitude cyclones have fronts and are larger.
D)Hurricanes strengthen with height, while middle-latitude cyclones weaken with height.

Question

Quizplus · Accepted Answer

Hurricanes and middle-latitude cyclones differ in several ways. One of the key differences is the presence of fronts. Middle-latitude cyclones have fronts that separate different air masses with different characteristics, while hurricanes do not. Additionally, hurricanes are generally smaller in size compared to middle-latitude cyclones.

Answer: B 
 Hurricanes derive their energy from the transfer of latent heat released by the condensation of water vapor, while middle-latitude cyclones derive their energy from the horizontal temperature contrasts between air masses. This is why hurricanes are often referred to as "heat engines."
