Abstract:
Blackadar’s inertial relaxation of the nighttime boundary layer is modified to account for the finite scale of the pressure gradient normal to the jet. Even though this horizontal dimension may be several thousand times the depth of the daytime convective layer, it severely reduces the period of the free oscillation in the relaxation process and replaces the harmonic acceleration of the jet with a linear growth rate.
