Abstract
We study the properties of subcritical Rayleigh-Bénard rolls induced by a triggering velocity applied to one side of a fluid layer maintained in controlled subcritical conditions. The induced rolls are spatially damped exponentially with increasing distance from the position of the triggering velocity. We point out a remarkable critical behavior of a characteristic penetration length . The values of and are in perfect agreement with those calculated according to the Landau-Hopf model.
