Abstract

Starting from the almost compressible 2-D Oberbeck–Boussi nesq system, characterized by an extra buoyancy term which is pressure-dependent, we write the corresponding Lorenz system and observe a larger instability with respect to the classical model in which the buoyancy is proportional to the temperature deviation only.
