Nonlinear evolution of unstable solar inertial modes: The case of viscous modes on a differentially rotating sphere
Muneeb Mushtaq, Damien Fournier, Rama Ayoub +2
On the Sun, the inertial mode with the largest observed amplitude (rms velocity exceeding m/s) is the high-latitude mode with longitudinal wavenumber . In two dimensions,…
