Abstract

Based on fluctuational observations of three-component wind velocity (u′, v′, w′) and temperature, T′, from a meteorological tower of 325 m located in Beijing, China, a number of turbulent linear correlation coefficients are calculated using a local scaling approach for turbulence statistics. The further applicability of this scaling is investigated by the formulation of similarity relationships for correlation coefficients of momentum transfer e.g., |r uw |, |r vw | and |r uv |, heat transfer e.g., |r uT |, |r vT | and |r wT |, and the ratios |r wT /r uw | and |r vT /r vw |. Under various stratifications, empirical similarity relationships for most of these correlation coefficients are derived to be function of a single local stability parameter and found to be in good agreement with experimental results.
