Abstract
The atmospheric surface layer turbulence statistics and surface fluxes during the winter season over Anantapur, a semi-arid region, are investigated using sonic anemometers mounted 10 m and 18 m above ground level on a 32-m meteorological tower. This paper aims to investigate the applicability of Monin–Obukhov similarity theory and to understand the influence of wind speed on the turbulence intensities. Results reveal that normalized velocity variances follow 1/3 power law in unstable and stable conditions, while approaching constant values in the near-neutral conditions. The qualitative dependency of normalized velocity variances on stability is in agreement with past studies.
