Abstract

http://dx.doi.org/10.5902/2179460X13222

In this study is analysed an autocorrelation function suggested by Frenkiel (Frenkiel (1953)), to described negative lobes in themeandering phenomenon of the horizontal mean wind vector. This function is a hybrid expression constituted by turbulent andmeandering parameters which describe pure and connected states of turbulence and meandering movements. Furthermore, theautocorrelation function is employed to fit meandering observations measured in north Brazil. An additional purpose is employdistinct mathematical and physical criteria to test this mathematical formulation. Employing the Frenkiel’s formula a formulationto the turbulence dissipation rate has been obtained.
