Abstract: | Summary A derivation of spectral energy functions for stable atmospheric boundary layers is presented for a local similarity regime.
Previous studies of this nocturnal atmospheric conditions were usually carried through purely kinematic modellizations. In
this study, the atmospheric turbulence energy content is derived from a dynamical viewpoint. This is achieved through the
use of the energy balance relation obtained by Rotta from Navier-Stokes equations. The result is an appropriate physical rooting
of the spectral energy curves known as Kaimal’s Isopleths.
