我们提出了一种在支持辐射非线性孤立波包或脉冲的系统中进行湍流传输的新机制。直接能量级联由绝热演化脉冲提供,其宽度和载波波长减小。逆级联是由于辐射的激发而产生的。该谱比波湍流的柯尔莫哥洛夫-扎哈洛夫谱更陡。
We propose a new mechanism for turbulent transport in systems which support radiating nonlinear solitary wave packets or pulses. The direct energy cascade is provided by adiabatically evolving pulses, whose widths and carrier wavelengths decrease. The inverse cascade is due to the excitation of radiation. The spectrum is steeper than the Kolmogorov-Zakharov spectrum of wave turbulence.
