Abstract:
Geophysical and plasma systems are often mentioned together because of the common basic nonlinear model used for them: Charney-Hassegawa-Mima equation (CHME). In both applications, zonal jets are often formed. This is important process which leads to transport barriers. I will describe two mechanisms, modulational instability and anisotropic inverse cascades, which lead to generation of the zonal jets.
