Resonant triad interactions on an extended equatorial β-plane
نویسنده
چکیده
Linear equatorial wave theory (Matsuno, 1966) has shown that equatorially trapped waves (particularly Rossby and Kelvin waves) are important waves in determining large scale climatic processes such as the El Niño-Southern Oscillation (ENSO; e.g. Philander, 1990; Clarke, 2008). Other factors that determine properties like ENSO periodicity and strength are stochastic processes (Kleeman, 2008). There are, however, nonlinear equatorial processes that are well observed and are thought to impact on phenomena such as ENSO, but many of these processes remain relatively poorly understood from a theoretical point of view.

Resonant triad interaction on an extended equatorial β-plane
The usual equatorial β-plane supports a range of wave types, including trapped baroclinic Rossby waves, a Yanai wave and a Kelvin wave, which are known to be important in equatorial wave dynamics, both linear and nonlinear. Here, we extend this model to the whole sphere, using a Mercator projection, in which the Coriolis parameter is retained in full, but the metric coefficients are approximate...
متن کاملWeak turbulence of short equatorial waves
We derive a normal form of nonlinear equations for short equatorial waves considered in the framework of the rotating shallow water model. We show dynamical splitting of equatorial Rossby and inertia-gravity waves. We derive an effective Hamiltonian for the short inertia-gravity waves and consider their kinetics using the weak turbulence approach. Stationary power-law energy spectra are obtaine...
متن کاملMultifrequency control of Faraday wave patterns.
We show how pattern formation in Faraday waves may be manipulated by varying the harmonic content of the periodic forcing function. Our approach relies on the crucial influence of resonant triad interactions coupling pairs of critical standing wave modes with damped, spatiotemporally resonant modes. Under the assumption of weak damping and forcing, we perform a symmetry-based analysis that reve...
متن کاملA generalized stability criterion for resonant triad interactions
It is well known that in any conservative system that admits resonant triad interactions, a uniform (test) wavetrain that participates in a single triad is unstable if it has the highest frequency in the triad, and neutrally stable otherwise. We show that this result changes significantly in the presence of coupled triads : with coupling, the test wave can be unstable to a high-frequency pertur...
