The velocity $u$ in this system is related to the vorticity $\\omega$ through the relations $u=\\nabla^\\perp \\psi$ and $\\Delta \\psi = \\Lambda^\\sigma (\\log(I-\\Delta))^\\gamma \\omega$, which reduces to the standard velocity-vorticity relation when $\\sigma=\\gamma=0$. When either $\\sigma>0$ or $\\gamma>0$, the velocity $u$ is more singular.
