Variabilité temporelle de l'ilot de chaleur urbain dans l'agglomération rennaise a partir des projections des modèles régionaux de 2030 a 2100.

Abstract : We observed urban heat island (UHI) in Rennes with two weather stations, the first in the downtown and the second in the suburb (Météo-France: Saint-Jacques). To predict the UHI's variability, we built a regression linear model (R²aj.= 0,65) with three predictors: temperature range, global ray and wind. CERFACS downscaled Global model ARPEGE Climat A1B, we used these output data to simulate the UHI evolution. The annual UHI range was constant over 1950-2099 but the intensive UHI (≥3°C) increased from 2030's. ARPEGE model showed an exponential increase of warm days over the period 1950-2099, however model underestimated UHI during these days.
