RepExtrem: Analysis and Mapping of heat waves in urban areas

Background and objectives

French meteorologist agency, Meteo-France, is producing maps resulting from the comparison of different forecast models in order to propose the most likely weather forecast. If models integrate data from a large special extend, urban areas are specific as they produce and store heats. Moreover that are sensitive places as they host a large proportion of people. As the city can be 10 degrees warmer than the surrounding countryside, as was the case in west Europe in August 2003. Furthermore, the climate change impact studies are still often limited to integrate the effects specific to the city. However a recent report (Ouzaeu et al 2015)[1] on possible scenarios for the next 100 years unfortunately confirms the risk of increased frequency of such phenomena on highly populated urban areas.
