Teaching Polar predictions to the next generation
Professor Ian Brooks spent two weeks in April as an invited lecture on a Polar Prediction School for graduate students and early career researchers.
The school is a joint initiative from the World Weather Research Programme (WWRP), World Climate Research Programme (WCRP), and Bolin Centre for Climate Research.
Polar regions are experiencing rapid changes to their climate; this is opening up new possibilities for businesses such as tourism, shipping, and oil and gas extraction. At the same time it brings new risks to these delicate environments. Effective weather and climate prediction is essential to managing these risks. The complexity of the polar environmental systems, and very limited measurements in these remote regions, make them very challenging environments to provide accurate forecasts for any time scale from days to decades.
The school was based at the Abisko Scientific Research Station in northern Sweden – an appropriately Arctic environment. It brought in 28 PhD students and early career researchers from all over the world and a wide range of disciplines for 9 days of lectures and practical exercises on the theme of polar prediction. Organised by Jonny Day (Reading University) and Gunilla Svensson (Stockholm University), the invited lecturers included James Screen (Exeter University), Helge Gossling and Thomas Jung (AWI), Cecilia Bitz (University of Washington), Don Perovich (CRREL), Erik Kolstad (University Bergen), Jen Kay (Colorado University), and Matthew Chevallier (Meteo France)
Ian lectured on measurement of the Arctic atmosphere and surface exchange processes with associated practical exercises based around measurements of near-surface wind and temperature profiles and the surface energy budget made from a micro-meteorology mast erected on the frozen surface of Lake Torneträsk. Radiosondes were released each day, with 1 day of intensive measurements where radiosondes were released every 3 hours for 24 hours to study the diurnal cycle of boundary layer structure. All the observations were drawn together on the final day to study the full range of processes governing the surface energy balance over the previous week. Other lectures and excercises covered chaotic systems and predictability, operational ocean prediction, modelling polar boundary layer processes, ensemble climate prediction, sea ice processes, and polar lows.
