Abstract. In atmospheric chemistry, a parameter called residence time is defined for each gas as T = M/F, where M represents the mass of the gas in the atmosphere and F is the total average influx or outflux, which in time averages are equal. In this letter we extend this concept from matter to energy which is also a conservative quantity and estimate the average residence time of energy in the atmosphere which amounts to about 56 days. A similar estimation for the residence time of energy in the Sun is of the order of 107 yr, which agrees with the Kelvin-Helmholtz time scale.

Short summary
We deduce that after a global thermal perturbation, the atmosphere would need about a couple of months to come back to equilibrium.
