A New Formulation for the Bowen Ratio over Saturated Surfaces

Journal of Applied Meteorology, 1996
Abstract Analytical expressions are presented for calculating the Bowen ratio, Bo = Hs/HL, from a quantity Bo* that is derived primarily from the surface temperature Ts and the assumption that the near-surface air is saturated (but not supersaturated) with water vapor.

A parameterization of Bowen ratio with respect to soil moisture availability

Advances in Atmospheric Sciences, 1995
The Bowen ratio (B) is impacted by 5 environmental elements: soil moisture availabillity,m, the ratio of resistances between atmosphere and soil pores,r a/rD, atmospheric relative humidity,h, atmospheric stability, δT, and environment temperature.

Further note on evaporation with fluctuating bowen ratio

Journal of Geophysical Research, 1964
In an earlier note [Webb, 1960a] a correction for the effect of fluctuating Bowen ratio on heat-budget estimates of evaporation from a land or water surface was derived, making use of subsidiary measurement of wind. The correction was found to be about 5 per cent during a summer-autumn investigation at Lake Eucumbene, southeast Australia [Webb, 1960b].

Influence of Bowen Ratio on Boundary-Layer Cloud Structure

Journal of the Atmospheric Sciences, 1996
Abstract An investigation of the influence of the ratio of surface sensible heat flux to latent heat flux, the Bowen ratio. on the structure of boundary-layer clouds is carried out utilizing numerical large eddy simulations (LES). The role of cloud-top radiational cooling, cloud-top temperature and moisture jump conditions, and wind shear are included ...

Spatial Averaging Bowen Ratio System: Description and Lysimeter Comparison

Transactions of the ASAE, 1992
Bowen ratio energy balance (BREB) measurements near a spatially divergent surface may not correctly partition energy fluxes when simply sampling over time. Thus, a Bowen ratio system was designed and constructed to perform spatial sampling and then evaluated by comparison to a precision weighing lysimeter at Bushland, Texas.

Bowen ratio estimates in return flow over the Gulf of Mexico

Journal of Geophysical Research: Oceans, 1997
The Bowen ratio (and associated turbulent fluxes at the ocean‐air interface) has been estimated over the Gulf of Mexico's continental shelf. These estimates are time‐averaged values during the outflow phase of a particular return flow event. The study uses standard buoy data and oceanic soundings from the Louisiana‐Texas Shelf Physical Oceanography ...

Inconsistent surface flux partitioning by the Bowen ratio method

Boundary-Layer Meteorology, 1989
Situations have been found in which the application of the Bowen ratio energy balance method has resulted in inconsistent partitioning between sensible and latent heat.

A year of Bowen ratios over the frozen Beaufort Sea

Journal of Geophysical Research: Oceans, 1989
The data set obtained during the Arctic Ice Dynamics Joint Experiment (AIDJEX) contains almost a year of 6‐hourly measurements of sensible (Hs) and latent (HL) heat fluxes over multiyear ice in the Beaufort Sea. Here I compute the Bowen ratio, Bo = Hs/HL, for each set of observations and plot histograms of Bo values for the four seasons, spring, summer,

A reversing temperature-difference measurement system for Bowen ratio determination

Boundary-Layer Meteorology, 1981
The design and performance of a reversing temperature difference measurement system are reported. This system employs five-junction copper-constantan thermopiles for the measurement of δT and δTw, while a linearized thermistor is used to measure Tw. Field performance has been checked against a precision lysimeter as well as against a second temperature
