A tropical night is a night when the thermometer does not fall below 20 °C. The temperature is measured under a weather protection roof at a height of 1.50 m above the ground. Although the number of tropical nights in Central Europe has been relatively low so far, it is increasing with global warming. They usually occur together with heat waves and are often accompanied by warm and humid weather.

This dossier consists of 4 maps on climate change in the Upper Rhine tri-border region and an accompanying text. The set contains 2 maps on the evolution of tropical nights in the near future (2021-2050) and 2 maps for the far future (2071-2100). For each of the two time horizons, 2 maps are also available: one map for a moderate climate change scenario (RCP4.5) and one map for the strong scenario (RCP8.5).
Below is the full text of the report in German and French.
