A publication of the first results from the Collaborative Research Center (CRC) on climate change in the Arctic can be found at Bulletin of the American Meteorological Society.
CRC Transregio, led by meteorologist Professor Manfred Wendisch from Leipzig University, is now in its second funding period. Other participants of the CRC Transregio are the Universities of Bremen and Cologne as well as the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research (AWI) and the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig.
“The cover shows a kind of international acclaim for the work of our whole group,” said Professor Wendisch. “The publication will help make our results more visible beyond the narrow circle of specialists, within the entire international community of meteorologists, oceanographers and climate scientists.”
The Arctic is warming two to three times faster than the rest of the world. This phenomenon is known as Arctic amplification. To understand this warming, the Transregional Collaborative Research Center (AC)³ was established in 2016. It includes modeling and data analysis efforts as well as observational elements.
The project has generated extensive ground, air, ship and satellite data on the physical, chemical and meteorological properties of the Arctic atmosphere, cryosphere and upper ocean, which are available to the Arctic climate research community.
Only about 1,700 data sets are stored on a freely accessible research data server, operated by the University of Bremen and the Alfred Wegener Institute. Global atmosphere-ocean models are continuously developed as part of the work of the Collaborative Research Center.
Scientists use existing and new data to identify short-term changes and indicators of long-term trends in Arctic climate variables. For example, they found that the Arctic atmosphere has become wetter and storm activity in the region has increased. Winter warming in the regions around Svalbard and the North Pole has increased, resulting in a decrease in the thickness of sea ice in the Fram Strait and the depth of snow on the ice.
To better link future results, researchers developed cross-cutting themes to answer key questions in four focus areas: lapse rate feedback, surface processes, Arctic mixed-phase clouds , and air mass transport and transformation.
