It is shown that for turbulence with a weak anisotropy, such spectra have the same dependence in k-space as the Kadomtsev–Petviashvili spectrum: E(k)∼k−2. However, the frequency spectrum has always the falling ∼ω−2, independent of anisotropy. In the strong anisotropic case the energy distribution relative to wave vectors takes anisotropic dependence, forming in the large-k region spectra of the jet type %G English %2 https://insu.hal.science/insu-02928491/document %2 https://insu.hal.science/insu-02928491/file/1.2928160.pdf %L insu-02928491 %U https://insu.hal.science/insu-02928491 %~ INSU %~ CNRS %~ UNIV-ORLEANS %~ OSUC %~ LPC2E
