Turbulence characteristics within the atmospheric surface layer of the coastal region of Qatar

Abstract The atmospheric turbulence characteristics in the coastal region of Qatar are analyzed using measurements conducted on shoreline (26.08 N, 51.36 E). micrometeorological data were collected, from August 2015 to September 2016, sonic anemometers (20 Hz) at three heights and a weather station atop 9-m tower. studied within framework Monin–Obukhov similarity theory (MOST), presence inhomogeneities generated by sea land surfaces coming together. results show wind north-west prevails during entire test period, with speed higher than that other directions. non-dimensional standard deviations velocity components found be consistent reported around world match suggested MOST scaling, relatively greater value for dissipation rate turbulent kinetic energy. flux Richardson number shows larger scatter under super-stable super-unstable regimes. Moreover, deviation temperature does not align model near-neutral very stable regimes, gradient some negative values Two different daily stability patterns, ‘orderly’ ‘disheveled,’ identified based conditions. orderly pattern descending ascending trend sunrise sunset periods, respectively, while disheveled days follow random no clear order. two patterns then related continuity direction relative shoreline.
