Parameterizations of some important characteristics of turbulent fluctuations and gusty wind disturbances in the atmospheric boundary layer

Parameterizations of several key characteristics of the high frequency turbulent fluctuations, the intermediate gusty wind disturbances, and their vertical profiles have been constructed with the physically based approach, and by the use of multilevel ultrasonic anemometer - thermometer observational data sets in the cold air mass. These characteristics are the kinetic energy and friction velocity of the turbulence and gust, the equivalent horizontal and vertical amplitudes and equivalent period of the gust train. The accuracy of parameterizations is statistically good (the coefficient of determination R-2 > 0.5). Some problems about their further improvement and application were also discussed in this paper. Parameterization of gusty wind disturbances separated from the high frequency turbulence is important in the models for calculation and prediction of emission and entrainment of aerosol particles in the atmospheric boundary layer, because the role of turbulence is diffusion, but gusty wind disturbances act as small scale advection to entrain particles into the upper part of the atmospheric boundary layer.
