The sum of the sensible heat and latent heat contained in air is described as-

The total heat content of moist air is called enthalpy. It represents the sum of the sensible heat (the energy needed to raise the air’s temperature) and the latent heat (the energy associated with the water vapor present as it changes phase). So enthalpy captures the entire energy content per unit mass of moist air. In psychrometric terms, it’s described by h ≈ c_p,air·T + w·(λ + c_p,v·T), or a common simplified form h ≈ 1.006T + w(2501 + 1.86T), with T in °C and w the humidity ratio. Humidity ratio only measures moisture content, not energy; specific heat is the amount of energy to raise temperature per mass, and relative humidity describes how close the air is to saturation, not its total heat content.
