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.
