# Strong Imbalanced Turbulence

@article{Beresnyak2007StrongIT, title={Strong Imbalanced Turbulence}, author={Andrey Beresnyak and Alex Lazarian}, journal={The Astrophysical Journal}, year={2007}, volume={682}, pages={1070 - 1075} }

We consider stationary, forced, imbalanced, or cross helical MHD Alfvénic turbulence where the waves traveling in one direction have higher amplitudes than the opposite waves. This paper is dedicated to so-called strong turbulence, which cannot be treated perturbatively. Our main result is that the anisotropy of the weak waves is stronger than the anisotropy of strong waves. We propose that critical balance, which was originally conceived as a causality argument, has to be amended by what we…
