“…Building aspect ratios are expected to play a significant role in so-called 'topological dispersion' , Jerram et al 1995, Belcher 2005, where the presence of the obstacle (building) enhances the lateral dispersion of the plume. This effect is greatly enhanced for some wind directions when the building has a form other than the classic cuboid, as evidenced in the few studies involving such types of buildings (see, e.g., MacDonald, 1998b;Yee and Biltoft, 2004;Milliez and Carissimo, 2007).…”

“…The results of the following references - Uehara et al (2000), Christen et al (2003), Moriwaki et al (2003), Offerle et al (2003), Rotach et al (2003), and Mutoh and Narita (2005) -are expected to be very useful. The scaled model experiments are also important, such as Yee and Biltoft (2004), Pearlmutter et al (2005), and Narita et al (2006). The results of the detailed simulation in the urban canyon space such as Kanda et al (2004) are useful to develop the urban canopy model.…”

Abstract:In recent years, problems concerning the urban climate-including the urban heat-island effect and urban air pollution -have attracted much attention in terms of the widespread urbanization in many parts of the world, including Japan. Assessment tools for urban climate are very important to understand effective countermeasures for heat-island mitigation. In this paper, various assessment tools are introduced and classified according to corresponding modelling scales. Special attention is given to the recent progress in Japan. It is shown that these assessment tools are very powerful at estimating the effectiveness of countermeasures. Furthermore, these assessment tools should become design tools for practical applications in the future.

“…[7]. Figure 8 shows the layout of the mock urban setting test (MUST) [43,44]. In this experiment 120 CONEX containers were arranged in a regular grid over a 200 m square area, giving an array footprint area density of 8% (contrast this with the high density of buildings in central London shown in Figure 2).…”

Many models exist for predicting the atmospheric transport and dispersion of material following its release into the atmosphere. The purpose of these models may be to support air quality assessments and/or to predict the hazard resulting from releases of harmful materials to inform emergency response actions. In either case it is essential that the user understands the level of predictive accuracy that might be expected. However, contrary to expectation, this is not easily determined from published comparisons of model predictions against data from dispersion experiments. The paper presents and reviews the methods adopted and issues involved in comparing the predictive performance of atmospheric transport and dispersion models to experimental data, by reference to a number of experimental data sets and comparison results. It then presents an approach which is designed to make the performance of atmospheric dispersion models more transparent, through clearly defining the basis on which the comparison is made, and comparing the performance of the chosen model to that of a reference model. Such an approach establishes a clear baseline against which the accuracy of models can be evaluated and the performance benefits of more sophisticated approaches quantified. The use of a simple analytic reference model applicable to continuous ground level releases in open terrain and urban areas is shown as a proof-of-principle.
