Place the events that form hurricane-force winds in order.
a. A thunderstorm cluster forms
b. warm moist air rises in the center of the thunderstorm cluster
c. a strong pressure gradient produces wind
d. the Coriolis force causes winds to rotate
e. as air cools at the top of the eyewall, it warms and expands, decreasing the pressure further
f. centrifugal force pushes the air outward reducing pressure in the eye
