Abstract
From a three-dimensional primitive-equation
model, we simulate the propagation of a
typhoon-induced mesoscale eddy in an open ocean.
Although the eddy energy is confined in the upper 250
m near the surface, it still can leak energy by radiating
Rossby waves into the lower ocean. As a consequence, a
cyclonic eddy translates toward northwest and loses both
its kinetic energy and the available potential energy
during its evolution. Therefore, a typhoon-induced
cyclonic eddy at low latitude is incapable to affect
Kuroshio to the east of Taiwan.
