摘要：

A state variable pi(0,s) most sensitive to isopycnal thermohaline variations and least correlated with the density field is proposed. pi is constructed so that its diapycnal gradient d(p)pi is related to the density gradient ratio Rp:d(p)piapproximate to(1 + Rp)/(1-R-p). It is simultaneously a tracer conserved by isentropic motions, and an indicator of diffusive stability. It is useful for the combined description of interleaving and double-diffusive processes at the boundary between water masses. (C) 2002 Elsevier Science Ltd. All rights reserved.
