Monin-Obukhov Length On Stability Conditions

Abstract
The mixing height is one of the most important parameters in air pollution
studies since it determines the vertical extent of the layer in which pollutants are
mixed and dispersed. In this study, the temporal evolution of the Mixed Layer,
for different meteorological conditions during daytime-nightime transition, has
been evaluated by a semi-empirical estimate of boundary layer parameters like
the Monin-Obukhov and the roughness length ZQ. Preliminary results mainly
based on data from Dodge City (Kansas) and from Florence (Italy) are
presented.
1 Introduction
The mixing-depth concept is based upon the principle that heat transferred to the
atmosphere at the earth surface results in convection, vigorous vertical mixing,
and establishes a dry-adiabatic lapse rate. The depth thr
