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 ...

A simple system for automated long-term Bowen ratio measurement

Agricultural and Forest Meteorology, 1993
Abstract The Bowen ratio method is widely used to estimate fluxes of sensible heat and evaporation between a crop and the atmosphere. The most critical points of this method are the measurements of vertical humidity gradients, and long-term operation.

Partitioning of Evapotranspiration Using Lysimeter and Micro‐Bowen‐Ratio System

Journal of Irrigation and Drainage Engineering, 1994
The present study estimated evaporation E and transpiration T losses separately during various growth stages of a tomato crop (Lycopersicon escallen mill. UC 82 variety), in Davis, California.

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.

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 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

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,

Objective Criteria for Rejecting Data for Bowen Ratio Flux Calculations

Journal of Applied Meteorology, 1982
Abstract In addition to the inherent problem of accumulating errors of measurement of net radiation and subsurface heat flux, the Bowen ratio energy balance method often produces totally unacceptable sensible and latent heat fluxes: wrong signs (directions) and extremely inaccurate magnitudes of the fluxes, or both. These problems are due to resolution
