Nonmodal Instability,ments show that nonmodal perturbations must always decay as .. However, plane Couette flow is always unstable in the laboratory in a broad range of Reynolds numbers where all normal modes are stable. Orr pointed out in 1907 that nonmodal disturbances may exhibit a transient growth that may push thei

Nonlinear Equatorial Waves,litude waves and likewise the vertical structure of a baroclinic eigenfunction. East-west, equatorial waves are free both to propagate and also to evolve; the zonal-and-time amplitude function, .(., .), satisfies one of several generic PDEs or PDE systems. Each one-space-dimensional PDE is derived b

Nonlinear Wavepackets and Nonlinear Schroedinger Equation,initesimal amplitude sine wave) multiplied by an “envelope” or “modulation” function that slowly varies in both space and time and satisfies the cubically-Nonlinear Schroedinger (NLS) equation. The coefficient of the nonlinear terms, the “Landau constant”, has many discrete singularities at various

Producing Adult Readers: 1930–50d the equator. Jets parallel to, rather than perpendicular to, the mean wind arise at low latitudes. Surface jets in opposite directions alternate in latitude. Vertically, jets of alternating signs are stacked one atop the other in the abyssal equatorial ocean like a stack of pancakes. The equatoria

U.S. Web Accessibility Law in Depthly analyzed for estimated error, culminating in a full four-dimensional separation of variables. The general solution to these approximate equations is a superposition of normal modes. Each mode is the product of four one-dimensional factors. The latitudinal structure of the modes is a Hermite funct

Overview of Accessible Technologiest that has been extremely useful in low latitude dynamics. The “long wave” approximation, which might equally well be dubbed the “low frequency” or “meridional geostrophy” approximation, filters gravity waves while retaining Kelvin and Rossby waves. The key assumption is that there is geostrophic ba
