Abstrakt: The time and space derivatives of the wind vector components and their products are analyzed for the cases where the components are split into deterministic, meso-gamma-scale, and turbulent parts. Ultrasonic thermoanemometer measurements in the surface air layer with are used for the analysis. The values and the variability ranges of the derivatives are estimated including meso-gamma-scale variations in the wind field. The variability ranges of these derivatives and the "classical" derivatives (only deterministic and turbulent components are considered) are compared. It is shown that meso-gamma-scale variations in the wind vector components can be no less important than the turbulent parts, which are included in the classical simulation (prediction) of the wind field with high space and time resolutions.
