Climatic conditions and thermal stress in Stuttgart: A comprehensive analysis

In this comprehensive analysis, the climatic conditions and thermal stress situations in Stuttgart were examined. The aim of the study was to create a solid database for climate-conscious urban planning and to validate climate simulations through detailed measurements. The researchers used the cuboid method to simulate the frequency of heat stress in the city with a spatial resolution of 100 m. The results showed that the number of heat stress days varies depending on terrain and land use, with a higher frequency found in urban areas. The projections suggest that a significant increase in heat stress days is expected between 2031 and 2060, particularly in industrial and commercial areas. The detailed results can be read in the final report of the cooperation between Stuttgart and the German Weather Service.

Stuttgart, as one of Germany's leading cities, is facing the challenges of the changing global climate. Rising temperatures and more frequent heatwaves are impacting urban planning and residents' quality of life.

The applied cuboid method proved to be an innovative approach to enable a detailed simulation of heat stress frequency in urban areas. The spatial resolution of 100 m allowed precise insights into the distribution of thermal load to be gained. The method was based on a careful combination of measurement data, climate models and topographical information, which provided a realistic picture of the climatic conditions in Stuttgart.

The results of this study make it clear that the frequency of heat stress days depends heavily on topography and land use. Densely populated and built-up areas such as the city center were particularly affected by increased heat stress. Green spaces and parks, on the other hand, often provided relief amid the extreme temperatures.

The findings regarding future development in industrial and commercial areas are particularly alarming. A significant increase in heat stress days is expected there in the coming decades, which could have significant impacts on the health of residents and working conditions.

The study provides important information for urban planning and suggests that Stuttgart will be increasingly confronted with heat waves and heat stress in the coming decades, especially in the summer months. There is an urgent need to take appropriate measures to prepare the city's infrastructure, buildings and residents' lives for the challenges ahead.

The present study on the climatic conditions and thermal stress in Stuttgart provides a solid basis for the development of future strategies and adaptation measures. The knowledge gained is of great importance in order to ensure the well-being and quality of life of Stuttgart's citizens, even under changing climatic conditions. It is expected that the study can make a valuable contribution to addressing the challenges of climate change.

The research was carried out in close collaboration between Stuttgart and the German Weather Service and is available to the public as a final report.
