On the definition of the flux of sensible heat
Boundary-Layer Meteorology, 1982The definition of the sensible heat flux is examined in the light of a paper published by Brook (1978). We show that the convergence of the flux defined in this paper and that of the standard definition are related to different quantities and that care must be taken to ensure that compatible definitions are used.

On the Variability of the Fluxes of Momentum and Sensible Heat
Boundary-Layer Meteorology, 2005Direct measurements of the air-sea turbulent fluxes of momentum and heat, along with surface currents, waves and supporting meteorological variables, were acquired during a recent field campaign. Surface currents, measured from a very high frequency radar, were found to steer the stress away from the mean wind direction.

Partition of sensible heat fluxes into bare soil and the atmosphere
Agricultural and Forest Meteorology, 1996Energy exchanges between a bare soil and the atmosphere depend on both soil parameters and meteorological conditions. The present work has been designed to describe the sensible heat partition between soil and the atmosphere, and to develop simple methods for calculating soil heat flux from soil properties and meteorological data.

Sensible and latent heat flux estimates in Antarctica
1993The assumption has been made that the net annual contribution of water by the processes of deposition and sublimation to the Antarctic Ice Sheet is zero. The U.S. Antarctic Program started installing reliable automatic weather stations on the Antarctic Continent in 1980.

A study of surface sensible heat fluxes with Large Aperture Scintillometers
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004Large Aperture Scintillometers (LAS), Bowen ratio and eddy covariance measurements were employed to study sensible heat flux over homogeneous bare soil surface from March 20/sup th/ to April 20/sup th/, 2002, at XiaoTangshan area, Beijing. The diurnal variation of sensible heat flux from LAS is analyzed in this paper, and the relation between sensible ...

Description and evaluation of a sensible heat flux detector
Boundary-Layer Meteorology, 1977An eddy-correlation method is the basis of a newly-developed sensible heat-flux detector which collects air temperature information proportional to the vertical wind speed in two electronic counters, one for upflow and one for downflow. The current model uses fast-responding sensors for vertical velocity and air temperature, but the principle should be

On estimating the sensible heat flux over land
Agricultural Meteorology, 1978Abstract The sensible heat flux from a land surface can be estimated from the ground temperature, and the air speed and air temperature at a single height in the surface layer. To test this technique, a study was made over a newly-planted wheat field in southwestern Kansas.

Deduction of the sensible heat flux from SODAR data
Advances in Atmospheric Sciences, 2008A new method for deduction of the sensible heat flux is validated with three sets of published SODAR (sound detection and ranging) data. Although the related expressions have previously been confirmed by the author with surface layer data, they have not yet been validated with observations from the boundary layer before this work.

Sensible and latent heat flux over natural bog vegetation
1995Abstract Goudriaan's crop model is tested for its ability to describe the energy balance of a natural bog vegetation. Data used to drive the model were collected during the summer of 1994. Model results were compared with field data obtained by means of the eddy correlation technique.

Sensible heat flux measurements with a yaw sphere and thermometer
Boundary-Layer Meteorology, 1970A yaw sphere has been designed that measures a quantity that is proportional to the vertical heat flux. The method is described, and some comparisons are given with measurements made with a three-dimensional pressure-sphere anemometer, in combination with a fast-response thermometer.
