Abstract

Wind speed time series recorded during stable low wind speed conditions are typically non-stationary, with large horizontal oscillations, commonly known as meandering. In this paper, two wavelet-based methods are proposed to obtain lateral dispersion coefficients from such time series. These methods, associated with a specific wind model, have been tested by using wind velocities recorded, with an ultrasonic anemometer, on a typical suburban site located in the southern part of the Paris region (France). Both of them give similar results and differ from classical Briggs's and Doury's parameterisations for standard deviations.
