[Phys-L] Hurricanes



A mass of air gains kinetic energy at the expense of thermal energy
over the ocean. After hitting the land the kinetic energy is rapidly
dissipated due to "friction." That is a very simplified description of
the hurricane phenomenon. But is it oversimplified to the point of
being wrong? In other words what is the main cause of the rapid
decrease of destructiveness, friction against the land or not being in
contact with the ocean (a supply of thermal energy)? Speculations about
ways of causing hurricanes to loose kinetic energy, before the land is
hit, might have some pedagogical value at this time. Take advantage of
this opportunity. Promote inventiveness and discuss student's proposals
in classes.
