论文摘要
带有实际幅度的理想波三合会的动力学具有众所周知的nambu代表，能量和肠道作为保护定律。在这里，我们得出了具有恒定强制性系统的NAMBU表示。这些方程已应用于在地形被强迫的大气中的罗斯比 - 霍维兹波的三合会。保护法是基于对未强制幅度的关系，以及由总能量加上涉及未强制振幅的术语给出的哈密顿量。不稳定波数的强迫会导致充电周期。
The dynamics of an ideal wave triad with real amplitudes has a well-known Nambu representation with energy and enstrophy as conservation laws. Here we derive Nambu representations for systems with constant forcings. These equations have been applied to triads of Rossby-Haurwitz waves in the atmosphere where they are forced with orography. The conservation laws are based on relations for the unforced amplitudes and a Hamiltonian given by the total energy plus terms involving the unforced amplitudes. The forcing of the unstable wavenumber causes a recharge cycle.
