The Bowen Ratio is the ratio of sensible heat flux to latent heat flux, so presumably it gives some information about the relative importance of these processes. But it is not clear how this information can be used to make inference about a system (e.g. the land-air interface of a corn field).
What are some uses of the Bowen Ratio?
What are typical values, and what is the range of meaningful values (e.g. under what conditions does $B_o\to\pm \infty$?)
