Large- and small-scale turbulent spectra in MHD and atmospheric flows

In the present review we discuss certain studies of large- and small-scale turbulent spectra in MHD and atmospheric flows performed by S. S. Moiseev and his coauthors during the last years of his life and continued by his co-authors after he passed away. It is shown that many ideas developed in these works have not lost their novelty and urgency until now, and can form the basis of future studies in this field. scale turbulence behavior remains insufficiently studied as yet. Therefore, the results of the study of the effect of correlation characteristics of an external random force on the spectrum generation in this spectral region obtained by Gordienko and Moiseev (1998, 1999) are especially significant. In the present review, we examine the results of the study of universal spectral behavior of turbulent velocity fluctuations in MHD and atmospheric flows.
