A comparison of spectral and cospectral characteristics of dynamic and thermal turbulent fields in weakly stratified boundary layers
Abstract
The turbulent fluctuations of temperature and two components of velocity have been measured with hot and cold wires in the I.M.S.T. Air-Sea Interaction Simulation Tunnel and at the Grau-de-Vendres micro-meteorological site in near neutral conditions. Direct and indirect estimates of the fluxes of momentum and sensible heat are compared. The non-dimensional production and dissipation functions for kinetic energy and temperature variance in Monin-Obukhov theory are estimated. The spectral and cospectral macrostructures are compared with the Kansas data. Fulachier and Dumas's extension of the Reynolds analogy to the spectral structures of the temperature and velocity fields is verified.
