ABSTRACT
One of the main components necessary to build urban climatic maps (UCMaps) and to produce climatic guidelines for urban planning is knowledge of the wind regimes of a region. A key issue to assess the urban ventilation is to use at least hourly or sub-hourly wind data and display it in a proper meso-climatic scale of analysis. This can be done by using state of art Computational Fluid Dynamics (CFD) and linearised models. The first category (CFD) has the advantage of accurate wind flows, but needs more computational resources and has a limitation when the integration of all directions is needed. Linear models are better suited to this task because the models are more accessible and real wind data can be used to assess wind speed and directions (Prata, 2005; PrataShimomura, 2010; Lopes et al., 2011).
