Modelling and measurements of the atmospheric boundary layer in Sofia, Bulgaria
The evaluation of mesoscale model simulations against experimental data on the vertical profiles of mean meteorological parameters and surface turbulent momentum and heat fluxes for Sofia, Bulgaria, is presented. The simulation of the vertical profiles is currently a weak point in mesoscale modelling, and needs investigation in view of the numerous practical applications.Keywords: Bulgaria, ...

Potential Dispersion Modeling Uses of Archived NOAA Forecast Model Data
A newly-developed generation of air quality simulation models has the potential to use profiles of wind, temperature, and turbulence, as well as improved mixing height determination, measures of surface heat flux, and a host of other meteorological parameters. Several numerical weather prediction models that generate these comprehensive data sets are routinely being run by the National Oceanic ...

Entropy analysis of laminar-forced convection in a pipe with wall roughness
Momentum and heat transfer rates, as well as entropy generation have been numerically investigated for fully developed, forced convection, laminar flow in a micro-pipe. Compressible and variable fluid property continuity, Navier-Stokes and energy equations are solved for various Reynolds number, constant heat flux and surface roughness cases; entropy generation is discussed in conjunction with ...

A new Russian regulatory dispersion model "MEAN" for calculation of mean annual concentrations and its meteorological pre-processor
A new Russian regulatory dispersion model "MEAN" is based on integration of the analytical expressions which approximate the numerical solution of the advection-diffusion equation (ADE). The meteorological preprocessor of this model uses routine information from the national meteorological network to estimate and process necessary dispersion parameters. Turbulent fluxes of the sensible ...

Deployment of a Deep Borehole Observatory at the High Lake Project Site, Nunavut, Canada
Abstract We deployed a deep permafrost observatory in a borehole at the High Lake Project Site (67°22'N, 1I0°50>W), Nunavut, Canada with the aims of (1) investigating the physical and chemical limitations on microbial life within such environments, (2) developing life-detecting technologies for the exploration of life on Mars and (3) constraining the hydrological and thermal parameters ...

Contrasting suspended covers reveal the impact of an artificial monolayer on heat transfer processes at the interfacial boundary layer
The highly variable performance of artificial monolayers in reducing evaporation from water storages has been attributed to wind speed and wave turbulence. Other factors operating at the interfacial boundary layer have seldom been considered. In this paper, two physical shade covers differing in porosity and reflectivity were suspended over 10 m diameter water tanks to attenuate wind and wave ...
