Experimental Study of the Turbulent Structure of the Surface Marine Atmospheric Boundary Layer over the Aegean Pelagos Under Etesian Winds
In order to study the physical processes of the turbulent transportation of mass and energy within the surface Marine Atmospheric Boundary Layer over the Aegean Pelagos, field measurements were conducted on the island of Skyros, mainly under the etesian winds, during summer 2011. A meteorological mast was installed close to the shoreline, instrumented with fast anemometer (sonic) and hydrometer measuring the three components of the wind, the virtual temperature and water vapor at 10 m height with a sampling frequency of 20 Hz. At the same mast slow response sensors were measuring wind speed and direction, temperature and humidity at three levels (2, 6 and 10 m). Weak stable to near neutral flows were recorded during the experimental period. The eddy correlation analysis revealed the momentum and heat fluxes values which are presented and discussed. The estimated values are related both with stability and wind speed variations.
