A cyclone formed outside the tropical zone near the boundary between warm and cold air is called :
- AExtratropical CycloneCorrect
- BTropical Cyclone
- CAnticyclone
- DTyphoon
Solution
Concept
Extratropical cyclone
Step-by-step solution
1. Tropical cyclones form over warm tropical oceans. 2. A cyclone that forms outside the tropics along the boundary (front) between warm and cold air masses is an extratropical (frontal) cyclone.
Explanation
Extratropical cyclones derive energy from temperature contrast across fronts and produce frontal precipitation in the middle latitudes.
Why the other options are wrong
Tropical cyclones and typhoons form in the tropics. An anticyclone is a high-pressure system.
Shortcut
Frontal = extratropical.
Common mistake
Choosing tropical cyclone.
Correct answer: A) Extratropical Cyclone
