Аннотация:Turbulent flows of a viscous incompressible fluid in a layer between rotating
concentric spheres under the action of the modulation of the velocity of one of the
spheres have been studied experimentally and numerically. The possibility of the
formation of turbulence with spectra qualitatively similar to spectra obtained in
measurements in the upper atmosphere is established: with the slope close to –3 at low
frequencies and close to –5/3 at high frequencies and with the negative third order
longitudinal velocity structure function. It has been shown that such spectra are formed in
the regions of a flow that are strongly synchronized under the action of the modulation of
the rotation velocity.
