Sažetak
Wind velocity at the town of Senj was measured at 13 m above the ground with a 3D ultrasonic anemometer operating at 4 Hz sampling frequency. The severe bora case that occurred on 07 January and lasted to 11 January 2006 is analyzed here. This data set is used for evaluation of the turbulent kinetic energy, TKE, and its dissipation rate, ε . Some considerations about defining turbulent perturbations of the bora wind speed are pointed out. The inertial dissipation method for estimation of ε is used. The empirical length scale parameter for this event is estimated with respect to ε and TKE.
