现有的几组较小规模的海洋和大气数据显示Kolmogorov-Obukov-Corrsin惯性范围在水平光谱的长度尺度至少达到几百米。有人认为，这些数据与这些惯性范围理论的假设不一致。相反，它是假设分层湍流的动力学解释这些数据。如果有效，这些动力学也可以解释其他地球物理流的类似动态范围内的强烈分层流的行为。
Several existing sets of smaller-scale ocean and atmospheric data appear to display Kolmogorov-Obukov-Corrsin inertial ranges in horizontal spectra for length scales up to at least a few hundred meters. It is argued here that these data are inconsistent with the assumptions for these inertial range theories. Instead, it is hypothesized that the dynamics of stratified turbulence explain these data. If valid, these dynamics may also explain the behavior of strongly stratified flows in similar dynamic ranges of other geophysical flows.
