Zusammenfassung |
In a simplified two-dimensional model of a buoyancy-driven overturning
circulation, we numerically study the response of the flow to a small
localized heat source at the bottom. The flow is driven by differential
thermal forcing applied along the top surface boundary. We evaluate the
steady state solutions versus the temperature difference between the two ends
of the water surface in terms of different characteristic parameters that
properly describe the transition from a weak upper-layer convection state to
a robust full-depth deep convection. We conclude that a small additional
bottom heat flux underneath the "cold" end of the basin is able to initiate
full-depth convection even when the surface heat forcing alone is not
sufficient to maintain this state. |
