The phrase "tendency_of_X" means derivative of X with respect to time. Air temperature is the bulk temperature of the air, not the surface (skin) temperature. The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase.

"Nonorographic" gravity waves refer to gravity waves which are not generated by flow over orography. The dissipation of gravity waves generates heating through an eddy heat flux convergence and through a viscous stress term.
