Mesures de la température et spatialisation de l’Ilot de Chaleur Urbain à Dijon
2015
The Territorial Climate Energy Plan (PCET) of the agglomeration of Dijon (Grand Dijon) includes ameasurement campaign (6 June to 28 September 2014). 50 Hobo proV2 thermometers were deployed. The selection of siteswas carried out so that the different types of urban environment (Oke, 2006) are documented. The Urban Heat Island (UHI)is discernible mainly at night, when radiative conditions are well established the day before. It is estimated to 1°C onaverage for the summer, 3-4°C during nights of fine weather. It reached 6°C during the warmest periods of the 2014 summer.A cool axis through the agglomeration shows that vegetation and water can sensibly mitigate the ICU effect.
Sensitivity of a climate model to urban form : application on Dijon Métropole
2020
The urban environment is at the crossroads of two complex systems with different temporalities : climate and society. The urban climate is a modification of the climate caused by the presence of a city. The most successful expression of this climate change by the presence of the city is the phenomenon of Urban Heat Island (UHI). In a global context of adaptation and mitigation to climate change and urban development, this phenomenon of ICU tends to increase, and its health impacts on populations to become more prominent. This work is aimed at improving the knowledge of the impact of urban form and urban development on the intensity of the UCI through the implementation of a decision support…
Formes urbaines et ilots de chaleurs : simulations et outils d'aide à la décision pour une ville durable
2017
National audience; Le monde s’urbanise. Selon les nations unies, plus d’un humain sur deux réside en milieu urbain et un septième de la population habite une agglomération millionnaire. Il s’agit d’une des mutations majeures de l’époque contemporaine. Chaque ville possède des caractéristiques propres (humaines, morphologiques...) mais l’Îlot de Chaleur Urbain (ICU) apparaît comme un phénomène inhérent et commun à toutes. En août 2003, l’Europe a subi une périodeestivale caniculaire ayant causé la mort de plus de 70 000 personnes dont 20 000 uniquement en France (Robine et al, 2008).
