A rate equation for soil-surface moisture fraction is developed which makes use of the more customary bulk soil moisture content, as well as the soil-surface evaporation rate minus precipitation rate. The two empirical constants involved are estimate

The conventional similarity theory for the planetary boundary layer is amended to contain the actual boundary-layer height scale h rather than the neutral rotation height scale u*/|f|.

A mesoscale mixed-layer model of the planetary boundary layer is applied to the flow past a mountain island during a cold air outbreak over the Kuroshio Current. Utilizing data taken during AMTEX '75, the governing equations are integrated in time to

Numerical integrations using a potential enstrophy-conserving scheme are presented for the flow within a mixed layer over hilly terrain using the hydrostatic shallow-water equations with a quadratic drag law. The mesoscale area treated is 150 km on a

A local interfacial boundary condition between a turbulent and non-turbulent layer is constructed in a manner that allows local entrainment. The Reynolds average of this equation produces a mean boundary-layer growth rate that contains additional ter

Mixed-layer models have been used to simulate low-level flows under a variety of situations, including flow over complex terrain and in the vicinity of coastal zones. The advantage of mixed-layer models compared to multilevel models is their simplici

The second-moment equations for buoyancy flux and density-fluctuation variance in the entrainment zone of a mixed layer are combined to yield an entrainment rate (we dependence having the nature of Turner's relation. That is, weq−1 is seen as a fun

An empirical evaluation of the stability functions a, b, c and of the friction and heat-transfer coefficients is made for the modified planetary boundary layer (PBL) similarity theory which utilizes the actual height h of the PBL as the physical para

A review is presented on laboratory modeling of diffusion downwind of a continuous point source within a boundary layer of well defined height with turbulence driven by buoyant convection. Results of using mixed-layer scaling are summarized and compa
