A study of three well-defined temporal intervals in a stably stratified night

A stable stratified night during the experimental SABLES-98 campaign was studied. It was found that the night could be divided into three distinct parts: an initial phase of transition, with significant changes in all the variables until a quasi-steady regime was reached; a second part dominated by the surface radiative cooling; and a final stage that revealed no significant changes. Each of these intervals was studied separately through the analysis of the vertical profiles, turbulence, spectra and the probability density functions.
