Abstract

The automatic IR hygrometer of turbulent micropulsings of absolute humidity is developed and is tested in nature conditions. The results of a series of experiments with use of this meter, and three-component sonic anemometer-thermometer are reported in this paper. The synchronous time series of fluctuations of absolute humidity, temperature and components of wind velocity are obtained. The vertical eddy fluxes of the water vapor, sensible and latent heat are calculated. The cross-correlation function, and auto-spectra of wind velocity components, humidity and temperature fluctuations are considered.
