What is a fresh air corridor, what is a cold air generation area and why do we need these areas? Climate change is noticeable and is exacerbated in cities by the heat island effect: sealed surfaces heat up considerably during the day, but hardly cool down at night and radiate the stored heat again. The green spaces in Munich's green belt, on the other hand, ensure that the overheated districts cool down at night. Maximilian Mühlbauer explains exactly how this works on a walk through the Landschaftspark West - one of the city's most important fresh air corridors.
