Abstract: The rate of evapotranspiration by irrigated alfalfa at Mead, NE (41°09?N; 96°30?W, elevation 354 m) reached record levels in 1976. Evapotranspiration was measured with precision weighing lysimeters in a field 1.9 ha in ...

Abstract: Distribution of local mass-transfer coefficients over saturated corrugated surfaces was measured in a wind tunnel. Wavy (sinusoidal) surfaces were used to represent field corrugations (furrows). Visualization techniques, ...

Abstract: Detailed knowledge of the advection of sensible heat is necessary to understand the energy balance of the evaporating surface in many parts of the world. Sensible heat advection can result from regional and/or local sources. ...

Abstract: Results are presented of micrometeorological measurements made over alfalfa and soybeans under conditions of sensible heat advection at Mead, Neb. The sensible heat advection phenomenon reported here is of a regional rather ...

Abstract: Thermal inversions induced by regional advection dominate the daytime climate of the central Great Plains during much of the growing season. The influence of these inversions on the turbulent transfer of momentum, sensible ...

Abstract: Spectra of vertical and horizontal velocity, air temperature and humidity fluctuations were analyzed from measurements made over a well-watered alfalfa crop under conditions of sensible heat advection. Vertical velocity ...

Abstract: Simultaneous measurements of humidity fluctuations over a crop made with a specially modified Lyman-alpha hygrometer and a fine-wire thermocouple psychrometer are compared. Standard deviations of the two sets of data are ...

Abstract: Turbulent fluctuations of vertical wind and fluxes of momentum, sensible heat and latent heat measured with a drag anemometer are compared to like data measured with other instruments. Means of the measured parameters ...
