  • On thermal staircases formed in process of multiple-diffusive convection in lakes

抄録

Thermal step structure bounded by stable/unstable interface is formed in lakes due to saline or turbid intrusion. Both thermal and solutal/turbid Rayleigh numbers were estimated for field and experimental staircases, among which, minor difference between silt and salt fingers was noticed as long as the particle size was less than ten microns. Rapid fingers forming a staircase with larger temperature jumps observed in a lake were found to be in the regime of salt fingers in deep oceans. Unstable staircase with thermal oscillation, moved downward in thermo-turbid diffusive regime with a settling rate, while it was static in thermo-solutal case. Turbidity Rayleigh number is usually smaller than salinity one, but strong thermohaline also moved down at the merginal stability.
