We report on simulations of two-dimensional fluids subjected to a temperature gradient, with an orthogonal gravity field suddenly switched on. Short-time behavior is dominated by rapid oscillations for the temperature and density field variables: the latter are interpreted as compressibility effects accurately described by linearized hydrodynamic equations until convective transport establishes itself.
