How does an extratropical cyclone dissipate?
A) The pressure gradient weakens as cold air displaces the warm air around the cyclone.
B) The pressure gradient strengthens as cold air moves aloft of the warm air.
C) The fronts move apart so there is no more interaction.
D) The cyclone moves out over water and loses strength.
E) Cold and warm air is mixed to make air whose temperature is an average of the two.

Question

Quizplus · Accepted Answer

An extratropical cyclone dissipates as the pressure gradient weakens due to the displacement of warm air by cold air. This causes the cyclone to lose strength and eventually dissipate. The other choices do not accurately describe the process of dissipation for an extratropical cyclone.
