Flow-aligned magnetic fields are shown to reduce stable mode activity, providing an interpretation for trends in turbulent transport.

My Ph.D. thesis. Chapters 2-4 are essentially identical to my first three papers. The introduction and conclusions help tie everything together, though. Also, the appendices in Chapter 4 describe a neat, unpublished calculation.

Analytic calculations show that stable (damped) inviscid modes are nonlinear driven by unstable modes in an unstratified shear flow.
