The method shows a temperature maximum principle and consistent velocity approximation. We present results of simulation runs in vertical slices of the North-East German basin. These indicate that the system is far from a stationary state, it shows quasi-periodic, and possibly chaotic behaviour. The chaos hypothesis is formulated based on the analysis of the Nusselt number time series obtaind from simulation runs.}, note = { \url {http://hdl.handle.net/11858/00-1735-0000-0001-3315-F}}, }
