Abstract:
The paper describes a prognostic model of the Doppler measurement accuracy based on equations for estimating the mean radial wind velocity and the one-dimensional model of the homogeneous atmospheric boundary layer. This model makes possible the numerical prediction of the radial wind velocity, its measurement error, as well as potential temperature, kinetic energy, and the turbulence dissipation rate for the meteorological situation, when the atmospheric stratification varies significantly during daytime. It is shown that the measurement error of mean radial wind velocity can vary widely depending on the day time. During day-time with increasing the turbulence intensity the measurement error grows, and in the evening and at night, when the turbulent boundary layer begins to collapse, the measurement accuracy increases first on the ground surface and then all over the height.
