Îlot de Chaleur Urbain et canicules : quelles relations ?

Abstract : With four years of measurements and a large sample of stations, the MUSTARDijon network allows for a detailed characterization of the Urban Heat Island (UHI), a warm season phenomenon. But UHI and maximum temperature values are out of phase at two distinct time-scales. Seasonally, the maxima of UHI occur from May to July, i.e. before the annual peak of temperature (July to August). At a daily time-scale, analysis of the two heat waves of July 2015 shows a lag of a few days between the peak of UHI and the heat wave. Two hypotheses are suggested to explain these lags: changes in radiative conditions and/or energy fluxes between the ground surface and the atmosphere.
