Intermittent convection and its consequences on the stability of the thermohaline circulation are investigated with an oceanic global circulation model (OGCM) and simple box models. A two-box model shows that intermittency is a consequence of the nonlinearity of the equation of state and of the ratio of heat and freshwater fluxes at surface versus the fluxes at depth. Moreover, it only occurs i...

Water temperature microprofiles at the air-water interface of a stratified lake were measured concurrently with moderate wind speeds 0.8–8.2 ms?1 above surface. The day-time measurements revealed cool skin effect water surface temperatures that triggers cooling and occurrence natural convection. Natural convection velocity scale mediates thickness diffusive thermal sublayer corresponding net he...

In this paper, we will show that solutions of the three-dimensional non-resistive and non-diffusive MHD-Boussinesq system are globally regular if initial data is axisymmetric swirl components velocity magnetic vorticity zero. Our main result extends previous ones on MHD Boussinesq system, method used here can also be applied to Rayleigh-Bénard convection system.
