GFI / BCCR Seminar Erlend Moster Knudsen: Hunting high and low: Measuring Arctic amplification with an icebreaker, two airplanes, several ground-based instruments and three dozens scientists
Main content
The two concerted field campaigns ACLOUD and PASCAL took place near Svalbard May 23 - June 26, 2017. Focusing on studying Arctic clouds and related feedbacks, they used the icebreaker Polarstern, the airplanes Polar 5 and 6 and the station Ny-Ålesund. In his presentation, Dr. Knudsen will share some first results from the campaigns, highlighting the dominating short-term variability in the synoptic development relative to the long-term background effect of the Arctic amplification. This includes anomaly analyses of cold air outbreaks and warm air advections observed during the campaigns. Finally, the presentation discusses the results in light of similar Arctic field campaigns (e.g., N-ICE2015) and its implications for the advancing Arctic scientific understanding.
Dr. Erlend Moster Knudsen is a climate researcher and science communicator, currently working as a postdoctoral researcher at the University of Cologne in Cologne, Germany, and deputy director of the NGO Pole to Paris in Christchurch, New Zealand. He holds a PhD from the University of Bergen, Norway, having studied the linkages between northern high-latitude cryospheric changes to large-scale atmospheric circulation. Also now is he focusing on Arctic climate change as part of the German transregional collaborative research center Arctic amplification: Climate relevant atmospheric and surface processes and feedback mechanisms (AC)³. Having lived in three countries and the Arctic, as well as conducted science communication in more than 20 countries, Dr. Knudsen strives to connect science and public interests across societies.
