Prognostic Equations for Turbulent Fluxes and Variances

Abstract

In the previous chapter, we summarized the equations needed to forecast mean wind, temperature, humidity, and pollutants. The last term in each of equations (3.5.3c) through (3.5.3g) contains a covariance like \( \overline {{u_{j}}^{'}{\theta ^{'}}} \) or \( \overline {{u_{j}}{}^{'}{c^{'}}} \). In order to use those previous equations, we can either evaluate the covariances experimentally, or we can derive additional equations to forecast the covariances.
