However, when the ground warms a layer of air near the surface, it expands and rises, carrying away energy from the surface.

An increased rate of evaporation and convection will move the additional energy at the surface to a higher layer in the atmosphere and because evaporation carries energy in what's called «latent heat» there will be no measurable rise in temperature near the surface as thermometers measure what's called «sensible heat».
