Sažetak
While bora macro-scale and even meso-scale features have ben intensively investigated in the past few decades, there are only few papers in the literature addressing the bora related turbulence. One of the reasons for this inadequacy is the lack of measurements suitable for micro-scale investigations. Those are high- frequency measurements of in situ wind speed and temperature in space (e.g., aircraft measurements) and in time (single point ground based measurements on e.g., meteorological towers/masts). Therefore, Department of Geophysics at the University of Zagreb conducted several projects in the past ten years within which high-frequency measurements of the wind speed and temperature along the eastern Adriatic coast have been performed. These are single point measurements at the town of Senj, Vratnik Pass and Pometeno Brdo (hinterland of the city of Split). However, all of those measurements were performed using sonic anemometers mounted on the towers/masts 10 m and higher above the ground, leaving the turbulence structure of the bora wind below 10 m unknown. Here we present a new state-of-the-art micrometeorological tower installed 200 m at the front of the new Maslenica Bridge. The tower is 10 m tall and is equipped with three levels of Gill WindMaster ultrasonic anemometers (2, 5 and 10 m) gathering the 3D wind speed and sonic temperature with the sampling rate of 20 Hz.
