On the Theory of Temperature Spectra in a Stably Stratified Fluid

Abstract

Aeron. Lab., Boulder, CO 80303, USA J (Journal-Article) M (Marine) It is shown that the Lumley-Phillips buoyancy subrange theory predicts the temperature spectrum to be proportional to K super(-3) at small scalar wavenumbers k-consistent with oceanic experiments (although those experiments measure vertical wavenumber k sub(3) rather than k). A previous derivation by Phillips does not apply to such small k. The predicted temparature spectrum is also shown proportional to velocity spectrum in the buoyancy subrange. Although its predictions are consistent with experiments, the a priori validity of buoyancy subrange theory still remains in question Ocean Technology, Policy and Non Living Resources (Q2) 1018101 -------------------------------------------------------------------------------- Record 168 of 1156 - ASFA 1978-1987
