Is spontaneous generation of coherent baroclinic flows possible?
Nikolaos A. Bakas, Petros J. Ioannou
Geophysical turbulence is observed to self-organize into large-scale flows such as zonal jets and coherent vortices. Previous studies on barotropic beta-plane turbulence have shown…
Statistical state dynamics of weak jets in barotropic beta-plane turbulence
Nikolaos A. Bakas, Navid C. Constantinou, Petros J. Ioannou
Zonal jets in a barotropic setup emerge out of homogeneous turbulence through a flow-forming instability of the homogeneous turbulent state (`zonostrophic instability') which occur…
Statistical state dynamics based theory for the formation and equilibration of Saturn's north polar jet
Brian F. Farrell, Petros J. Ioannou
Coherent jets with most of the kinetic energy of the flow are common in atmospheric turbulence. In the gaseous planets these jets are maintained by incoherent turbulence excited by…
Statistical state dynamics of jet/wave coexistence in barotropic beta-plane turbulence
Navid C. Constantinou, Brian F. Farrell, Petros J. Ioannou
Jets coexist with planetary scale waves in the turbulence of planetary atmospheres. The coherent component of these structures arises from cooperative interaction between the coher…
Emergence of non-zonal coherent structures
Nikolaos A. Bakas, Petros J. Ioannou
Planetary turbulence is observed to self-organize into large-scale structures such as zonal jets and coherent vortices. One of the simplest models that retains the relevant dynamic…
S3T stability of the homogeneous state of barotropic beta-plane turbulence
Nikolaos A. Bakas, Navid C. Constantinou, Petros J. Ioannou
Zonal jets and non-zonal large-scale flows are often present in forced-dissipative barotropic turbulence on a beta-plane. The dynamics underlying the formation of both zonal and no…
A theory for the emergence of coherent structures in beta-plane turbulence
Nikolaos A. Bakas, Petros J. Ioannou
Planetary turbulent flows are observed to self-organize into large scale structures such as zonal jets and coherent vortices. One of the simplest models of planetary turbulence is…
Emergence of large scale structure in planetary turbulence
Nikolaos A. Bakas, Petros J. Ioannou
Planetary and magnetohydrodynamic drift-wave turbulence is observed to self-organize into large scale structures such as zonal jets and coherent vortices. In this Letter we present…
