From April 2010 to June 2011, a three level tower (10, 20 and 40 m) was equipped with WindMaster Pro ultrasonic anemometers (Gill Instruments), measuring 3D wind speed and sonic temperature at 5 Hz sampling rate. The tower was mounted at the top of Pometeno brdo (Swept-away Hill, ≈ 600 m ASL) in Dugopolje, bora upwind site from the city of Split. During this period, anemometers captured multiple bora events in all annual seasons. Our focus here is on a strong, long-lasting winter bora event. We show that the obtained turbulence strength is highly sensitive not only to the length of the low-pass filter, but to its type as well. Also, we show that reconstructions of logarithmic wind profiles using required turbulence parameters are highly sensitive to the choice of statistical moments that represent these parameters.
