Turbulence with strong zonal flows occurs on all scales in nature, the most famous is the flow streams in Jupiter’s atmosphere. In fusion plasmas zonal turbulence is a feature of drift waves. The governing equation in geophysical fluid dynamics and in plasma physics has the same form and this equation and the properties of the flow will be discussed in the context of plasmas. In the model sheared flow is imposed by prescribing the background density gradient. Of the known solutions of bipolar and monopolar vortices only monopolar vortices survive due to the interaction between vortices and the destructive effects of the sheared flow. The longevity of the monopoles in different zonal flow configurations will be discussed and analysed.
