Turbulence Characteristics In The Surface Boundary Layer Over The South American Pampa.

This paper presents results of turbulence measurements made in the south of Brazil in the Pampa region. Data collected at 1Hz are used to calculate standard deviations of temperature and velocities. On the other hand data collected at 10Hz are used to study the behaviour of spectra and cospectra of turbulence in the surface layer. Dimensionless dissipation rates of turbulent kinetic energy and temperature variance are also presented. The framework of Monin–Obukhov Similarity theory is used and all results are compared with other experimental studies. [ABSTRACT FROM AUTHOR]
