Bioclimate 2005


A headache during the day, insomnia at night; many people are sensitive to changes in the weather in summer. Why is that? Because of our bioclimate. It encompasses all factors that influence any organism. The main parameters that have a direct impact on our heat balance are the temperature and humidity of our air, wind speeds and the thermal-physiologically effective radiation.

Berlin has gained comprehensive insights into the effects of the climate in the city and its surroundings through measurements carried out as part of the climate model FITNAH. Special emphasis is put on the thermal load. When metropolitans overheat temporarily, their cardiovascular system can take a big hit, especially if the heat persists through the night, when there is a minimal cooling effect. Many people find it difficult to sleep and suffer from reduced performance as a result.

It is therefore important to keep an eye on the thermal load in Berlin. To determine the latter, several parameters can be measured. The Predicted Mean Vote (PMV) , i.e. the “predicted average value”, was used here.

If you’re interested to see how Berlin’s climate and temperatures develop at night-time, you’ve come to the right place. Access our maps and data on the subject and much more here. Over the last few years, the PET (Physiological Equivalent Temperature) evaluation index has become the benchmark, however. Visit our Climate Analysis 2014 to access our map and information on the PET.
