✦ Synopsis

The onset of thermohaline convection in an anisotropic rotating porous layer of infinite horizontal extent is investigated. Numerical computations are made assuming horizontal isotropy in permeability. It is observed that (i) for certain parameters a bottomheavy arrangement destabilises a rotating anisotropic porous layer, (ii) the lower the anisotropy parameter, the higher the range of bottom-heavy solute gradient for which there is destabilisation, (iii) increase in the anisotropy parameter stabilises the system, and (iv) for some values of the parameters rotation destabilises the system, though in general, it has a stabilising effect.
