Abstract

Climate variability induced by surface cooling in a four-moving-layer model of the ventilated thermocline is studied. The perturbations propagate within the characteristic cones defined by streamlines in individual layers where the potential vorticity anomaly is created. Each time the characteristic cones cross a new outcrop line, the number of characteristic cones doubles. Thus, climate variability in a multilayer model can have very complicated structure in the horizontal plane, with anomalies of alternating sign. The vertical structure of such perturbations defines a class of dynamical thermocline modes.
