Resumen
A one-dimensional stable nocturnal boundary layer model of two-layers is constructed, which includes various meteorological processes: turbulence, radiation, interaction boundary layer - soil and boundary layer - synoptic flux. The model predicts the thermodynamic profiles; and two heights. One is born the boundary layer, and the other from the turbulent surface sublayer. The boundary layer evolves as. a system in contraction at night and expansion during the day, influenced mainly by strong radiative cooling or heating and soil type. Predictions agree with the profiles obtained by other authors.
