We consider a class of variational equations with exponential nonlinearities on a compact Riemannian surface, describing the mean-field equation of the equilibrium turbulence with arbitrarily signed vortices. For the first time, we consider the problem with both supercritical parameters and we give an existence result by using variational methods. In doing so, we present a new Moser-Trudinger-type inequality under suitable conditions on the centre of mass and the scale of concentration of both e(u) and e(-u), where u is the unknown function in the equation.
