Abstract
Modulated Rayleigh-Bénard convection is analyzed for high frequencies and large modulation amplitudes. The linear theory of Gershuni and Zhukhovitskii is generalized to the nonlinear domain, and a subcritical bifurcation to convection is found in agreement with the experiments of Niemela and Donnelly. The crossover between the high-frequency (‘‘Stokes layer’’) regime and the low-frequency regime studied previously is analyzed.
