The time dependent mixed-layer depth and temperature
response of a two-layer hydrothermodynamic ocean model to
a moving hurricane model was investigated. The hurricane
model was that of Elsberry, Pearson, and Corgnati (1974).
The maximum eye radius and hurricane intensity was bounded
to isolate ocean reaction from hurricane variance. The
ocean model was based on the upwelling model of O'Brien and Hurlburt (1972) in two dimensions and was located along
the path of the storm. The momentum and depth equations
in this model are treated semi-implicitly . Mechanical and
convective mixing was included and was found to be the
dominate cause of deepening of the mixed layer and cooling
of the ocean surface. Alternating regions of upwelling
and downwelling were produced in the wake of the storm as
a result of inertial waves caused by the passage of the
storm. The cases studied indicated a linear relation between
the wavelength and the storm translation speed.
