Many atmospheric dispersion models include only simpletreatment of surface features to estimate the wind profilesand stability parameters.

Detailed characterisation of theland cover, particularly in large and complex urbanconurbations, is especially important, as the surfacefeatures can vary significantly over the area.

Modeling a more slender ship hull while keeping the projected front and side area of the ship similar, yields an average decrease in total wind load of 5.9%.The use of SBLparameters derived from land cover data also yields moredetailed predicted annual CO spatial patterns especially inand around suburban areas.The performance of both versionsof the model for monthly CO concentrations has been comparedwith a range of statistical measures.Therefore, the mechanical air conditioning use can be postponed until the indoor air temperature is high and would, consequently, reduce the total building energy consumption.Thereby, a proper natural ventilation focus during the initial design stage could improve the building energy efficiency without compromising the indoor comfort conditions.Blockage effects caused by the domain boundaries are studied by comparing CFD results in the wind tunnel domain and a larger domain.The average absolute difference in numerically simulated and measured total wind load on the ship ranges from 37.9% for a simple box-shaped representation of the ship to only 5.9% for the most detailed model.In this study, satellite image was used in order to determine the zo.Semi empirical approach that incorporates both quantitative information (NDVI) from Landsat satellite image and qualitative information (land cover roughness) had been used.Blockage correction following the approach of the Engineering Sciences Date Unit underestimates the maximum lateral wind load up to 17.5%.Operational and meteorological requirements for terrain roughness classifications are developed.
