Received: 26 Jun 2009 – Published in Atmos. Chem. Phys. Discuss.: 23 Sep 2009Abstract. A novel methodology to derive the average wind profile from the Navier-Stokes
equations is presented. The development employs the Generalized Integral
Transform Technique (GITT), which combines series expansions with Integral
Transforms. The new approach provides a solution described in terms of the
quantities that control the wind vector with height. Parameters, such as
divergence and vorticity, whose magnitudes represent sinoptic patterns are
contained in the semi-analytical solution. The results of this new method
applied to the convective boundary layer are shown to agree with wind data
measured in Wangara experiment.
