Abstract
Turbulence characteristics in the surface layer of the coastal area of Akhtopol (Bulgaria) under conditions of the breeze circulation are measured. The measurements were carried out at the level of 4.5 m by means of three-component ultrasonic anemometer. To estimate the wind regime in the atmospheric boundary layer, the sodar data and synoptic charts were used. All turbulent characteristics except the correlation coefficient of the friction flow have an appreciable daily course in the case of the sea breeze. In the frontal zone, some characteristics demonstrate sometimes short-term variations of their numerical values. The sea-land front of the breeze circulation is effectively detected from the measurements of wind speed, wind direction, and temperature in the surface layer. It is also possible to judge about the breeze circulation type and turbulence structure in this layer on the basis of these measurements.
