More than half of the world’s population lives in towns and cities. By 2030 this number will swell to 70% with urban growth concentrated in Africa and Asia. Cities face two major problems; climate change (anthropogenic, due to increase of green house gases) and Urban Heat Island (UHI, due to urbanization and changed land cover). They can be additive or in opposition. UHI and climate change lead both to higher temperature, enhanced heat stress for human, animals and plants in urban areas.
The working group ‘Urban Climate and Health’ of Institute of Meteorology at Free University of Berlin concentrates on measurement (measuring campaigns, permanent & short time stations and also remote sensing) and modeling of urban climate parameters in urban areas. This group investigates the interaction between micro climate (temperature, humidity, precipitation and wind) and urbanization under climate change and its health effects to achieve sustainable urban development and effective climate change adaptation. This group has many years experience in high resolution climate modeling using dynamical and statistical downscaling as well as micro climate models up to 1 m, where the urban heat island intensity is also modeled.
