Measurement of Condensed Water Content in Liquid and Ice Clouds Using an Airborne Counterflow Virtual Impactor

Creator:: Twohy, Cynthia, Schanot, Allen J., and Cooper, William A.
Abstract:: Condensed water content (CWC) measured using a counterflow virtual impactor (CVI) with a Lyman-α hygrometer downstream is compared with that measured by other airborne instruments (a hot-wire probe, a PMS FSSP, and a PMS 2D-C).

On Kelvin Waves in Balance Models

Creator:: Allen, J. S., Gent, Peter R., and Holm, Darryl D.
Abstract:: The f-plane linear shallow-water equations support coastal Kelvin waves. These waves propagate along the coast and have zero velocity normal to the coast. It is shown that the balance equations also support coastal Kelvin waves, but these waves differ depending upon the boundary conditions imposed. Three different boundary conditions and...

Combined Effects of Wind-Driven Upwelling and Internal Tide on the Continental Shelf

Creator:: Kurapov, A. L., Allen, J. S., and Egbert, G. D.
Abstract:: Internal tides on the continental shelf can be intermittent as a result of changing hydrographic conditions associated with wind-driven upwelling. In turn, the internal tide can affect transports associated with upwelling. To study these processes, simulations in an idealized, alongshore uniform setup are performed utilizing the hydrostatic Regional Ocean Modeling...

Normal-Mode Instabilities of a Time-Dependent Coastal Upwelling Jet

Creator:: Durski, S. M., Samelson, R. M., and Allen, J. S.
Abstract:: The linear stability of a nearly time-periodic, nonlinear, coastal upwelling–downwelling circulation, over alongshore-uniform topography, driven by a time-periodic wind stress is investigated using numerical methods. The near-periodic alongshore-uniform basic flow is obtained by forcing a primitive equation numerical model of coastal ocean circulation with periodic wind stress. Disturbance growth on...
