Reflection of Yanai waves at eastern ocean boundaries
Washington State Convention Center
Dennis W. Moore, PMEL, Seattle, WA; and S. Schmidtko

When a Yanai wave hits an eastern boundary at x = 0 the reflection process generates a finite number of long Rossby waves or gravity waves that carry energy westward, plus a boundary trapped disturbance propagating poleward along x = 0. This poster explores the structure of the poleward-going disturbance, which is represented as an infinite series involving Hermite functions. The object is to describe this disturbance in detail and to determine for which frequencies it can be interpreted as a meridionally propagating Kelvin wave.
