Importance of the continuous spectrum in the excitation of sheared surface gravity waves
Jeffrey R. Carpenter
The initial value problem is solved for the excitation of long surface gravity waves in a continuously sheared flow. This reveals the presence of a continuous spectrum along side t…

Wave interactions in neutrally stable shear layers: regular and singular modes, and non-modal growth
Eyal Heifetz, Anirban Guha, Jeff Carpenter
In a recent letter, Carpenter and Guha (2019) compared the neutral modes of a smooth two dimensional shear profile without an inflection point to the modes of its corresponding pie…

Instability of a smooth shear layer through wave interactions
Jeff Carpenter, Anirban Guha
Wave interaction theory can be used as a tool to understand and predict instability in a variety of homogeneous and stratified shear flows. It is however, most often limited to pie…
