The investigation of low-wind cases measured during the Urban Turbulent Project campaign (Torino, Italy), the Large-Scale Biosphere-Atmosphere Experiment (Amazonia, Brazil) and in the Santa Maria meteorological tower (Santa Maria, Brazil) are presented to give some insight on the wind meandering phenomenon, i.e. the large, non--turbulent oscillations of the horizontal wind velocity and temperature. Through the analysis of the Eulerian auto-correlation functions and spectra meandering and not meandering cases are identified and their properties compared.

Abstract

The investigation of low-wind cases measured during the Urban Turbulent Project campaign (Torino, Italy), the Large-Scale Biosphere-Atmosphere Experiment (Amazonia, Brazil) and in the Santa Maria meteorological tower (Santa Maria, Brazil) are presented to give some insight on the wind meandering phenomenon, i.e. the large, non--turbulent oscillations of the horizontal wind velocity and temperature. Through the analysis of the Eulerian auto-correlation functions and spectra meandering and not meandering cases are identified and their properties compared.
