On the use of wet bulb temperature as an environmental index.

The cooling capacity of an atmospheric environment is examined with respect to a wet object of a given surface temperature. The maximum cooling capacity (MCC) is defined as the sum of the sensible and latent heat fluxes out of a unit area of the object. It is found that, for a given surface temperature and wind speed, the MCC is essentially a function of the wet bulb temperature of the ambient air with a very weak dependence on the ambient air temperature and pressure.-from Author
