Question 12

Which of the following statements correctly describes the physical conditions and atmospheric processes involved in the initiation and development of tropical storms?

Strong vertical wind shear in the troposphere promotes rapid storm development by accelerating the divergence of rising air from the eyewall.

Tropical storms rarely form within 5∘5^\circ5∘ of the Equator because the Coriolis effect is too weak to initiate the cyclonic rotation necessary to sustain a low-pressure vortex.

The primary energy source of a tropical storm is sensible heat transferred from surface ocean waters, requiring sea temperatures of at least 21∘C21^\circ\text{C}21∘C to a depth of 10 m10\text{ m}10 m.

Upon making landfall, increased surface friction causes a rapid decrease in central surface pressure, briefly accelerating the storm's maximum sustained winds.
