How do hurricanes pick up speed?
Select one:
a. by evaporating more and more water
b. by the Coriolis effect
c. by encountering more wind
d. by internal rotational energy
Homework Answers
Hurricanes pick up speed due to internal rotational energy. As air flows inward on a circular path, it speeds up to conserve angular momentum according to the equation:
where 
is angular momentum,
is the
mass of flowing air , 
is the velocity of the
wind and 
is the radius of the
path of the wind. As air flows inward, it traces a path of
decreasing radius, and hence speeds up to conserve angular
momentum.
