The Bowen ratio method is … WebThe Bowen Ratio (β) is used to express the partitioning of net radiation at a surface. Thus, Theoretically, in the absence of an atmosphere, β can vary from infinity (for a dry surface …
WebFeb 10, 2014 · The interannual variation of the Bowen ratio, through its effect on the warming extent of available energy to the ecosystem land surface air, heavily influences the ecosystem microclimate and affects the hydrological cycle at both regional and global scales. Although the precipitation amount in southeast China is not expected to change … WebThe conventional Bowen ratio surface energy balance method (BR method) is a relatively simple technique that in-tegrates net available energy with the ratio of the sensible and latent heat flux. The Bowen ratio can be determined by mul-tiplying the psychrometric constant by the ratio of the tem-perature and vapour pressure gradients (Bowen, 1926).
WebMar 6, 2024 · The Bowen ratio is used to describe the type of heat transfer for a surface that has moisture. Heat transfer can either occur as sensible heat (differences in temperature without evapotranspiration) or latent heat (the energy required during a change of state, without a change in temperature). The Bowen ratio is generally used to …
WebThe Bowen ratio obtained using equation 3.1 to equation 3.8 was combined with the available energy (R N-G) to obtain the sensible and latent heat fluxes using equation 3.7 and equation 3.8, respectively (Figures 2 and 3).
