A flow induced by buoyancy in neutral or stably (0<st) stratification or with an adiabatic ceiling (st=0) in an enclosure was analyzed numerically where st is the degree of stratification, and a new flow resulted from both stably stratification and thermal cylinders was found as follows: At 0≤st, the flow on the midplane had both a thermal cylinder flow (TCF) and the flow between TCFs, and a TCF developed to a small roof-shape flow, which parted right and left near the front, and layers were formed. Thus a large number of layers were generated intermittently. After the flow separation, at st=0 and a small st, one edge was fixed near the midplane, the other edge moved, and a layer was elongated. As a result, adhesive type layers were formed. At a large st, the whole of a layer left the midplane and moved to a side. As a result, a large number of layers, that is, breakaway type layers, were formed near the side.
