Alpha-effect in three-dimensional coherent vortex of conducting rotating liquid
Leon L. Ogorodnikov, Sergey S. Vergeles
We study one-point statistics of spiral turbulent pulsations on the background of three-dimensional large-scale vortex in a rotating fluid. Assuming that the helical flow is create…

Velocity structure function in a geostrophic coherent vortex under strong rotation
Leon L. Ogorodnikov, Sergey S. Vergeles
We consider analytically pair structure function of turbulent pulsations on the background of a coherent geostrophic vortex in a fast rotating fluid. The statistics of the turbulen…
