摘要

To study future thermal comfort in Germany, the perceived temperature PT is utilized, a thermal index which refers to a reference environment in which the sensation of cold and heat would be the same as under actual conditions.To calculate the thermal index PT, the German Weather Service DWD employs the Klima Michel Modell KMM, a complete heat budget model of the human body, which was developed by Jendritzky in 1979 as an operational tool for thermal assessment. The necessary input parameters for the KMM were obtained from different climate scenario runs conducted with the regional climate model of the German weather service, the COSMO-CLM.The results for the period 2001-2050 show an overall increase in number of days with perceived temperatures in the range of thermal comfort (0-20℃), although no significant trend can be detected for Freiburg. Several spatiotemporal trends are discerned, i.e. a larger increase in coastal areas compared to southern parts of Germany. The rise in number of days with thermal comfort takes place at the expense of a decrease in number of days with a slight cold stress.
