Climatic conditions and thermal stress in Stuttgart: A comprehensive analysis

This comprehensive analysis examined climatic conditions and thermal stress situations in Stuttgart. The aim of the study was to create a solid database for climate-conscious urban planning and to validate climate simulations through detailed measurements. 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 the terrain and land use, with a higher frequency observed in urban areas. Projections indicate that a significant increase in heat stress days is to be expected between 2031 and 2060, particularly in industrial and commercial areas. The detailed results can be found in the final report of the collaboration between Stuttgart and the German Meteorological Service.

Stuttgart, as one of Germany's leading cities, faces the challenges of a changing global climate. Rising temperatures and more frequent heat waves are impacting urban planning and the quality of life for its residents.

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

The results of this study demonstrate that the frequency of heat stress days is strongly dependent on topography and land use. Densely populated and built-up areas, such as city centers, were particularly affected by increased heat stress. Green spaces and parks, on the other hand, often provided relief amidst the extreme temperatures.

Particularly alarming are the findings regarding future developments in industrial and commercial areas. A significant increase in heat-stress days is expected there in the coming decades, which could have considerable consequences for the health of residents and working conditions.

The study provides important information for urban planning and suggests that Stuttgart will increasingly face heat waves and heat stress in the coming decades, particularly during the summer months. It is urgently necessary to take appropriate measures to prepare the city's infrastructure, buildings, and the lives of its residents for these future challenges.

This study on climatic conditions and thermal stress in Stuttgart provides a solid foundation for developing future strategies and adaptation measures. The findings are of great importance for ensuring the well-being and quality of life of Stuttgart's citizens, even under changing climatic conditions. The study is expected to make a valuable contribution to addressing the challenges of climate change.
