Long-term Development of Selected Climate Parameters

Summary

Climate in the capital – what was it like in the past, what is it like today and how will it potentially develop in the future? Six measuring stations positioned at strategic locations in and around Berlin hold the numbers and therefore the answers to these questions. They measure a variety of climate parameters including air temperature, precipitation and sunshine duration.

These measurements are used for long-term climate observations and allow us to assess the extent to which climate change is already affecting the region. The data evaluation focusses on observing the rising temperature levels. This includes especially the frequency of hot days with temperatures of 30 degrees Celsius and higher as well as tropical nights, during which your thermometer does not read below 20 degrees Celsius.

Another interesting aspect is the Llong-term mean temperatures derived from reference stations, i.e. average temperatures measured across a period ofacross several 30 years as stipulated by the World Meteorological Organization, are of interest here, as are meteorological climatic parameters, including summer days, hot days and tropical nights and their distribution. These Long-termmulti-annual means are especially important, as they can revealindicate long-term changes in the climate, relevant also for national and international comparisons.
