SUMMARY:Workshop on Polar Winter Climate and Processes
DESCRIPTION:Polar Winter Climate and Processes: Towards Filling Knowledge Gaps in the Understanding of the Coupled Climate System\n\n\nDownload the Workshop Programme PDF\nAccommodations PDF \n\n\n\n\n\n\n\n\n       \n\n\n\n\nPolar winter plays a critical role in various processes\, including sea ice growth\, snow accumulation\, surface energy balance\, atmospheric dynamics and chemistry. Current climate models struggle to accurately represent polar weather and climate\, especially during winter. These significant discrepancies hinder the reliability of these models in predicting and projecting future conditions in the Arctic and Antarctica. \n \nWhile previous studies have predominantly focused on summer\, it is crucial to explore winter conditions to gain a more comprehensive understanding of the entire climate system. To address this need\, we organize a workshop titled “Polar Winter Climate and Processes.” This workshop aims to bring together diverse research communities to examine the physical and chemical processes in the interconnected atmosphere\, cryosphere\, marine\, and terrestrial systems. Our goal is to facilitate the exchange of ideas\, present recent findings\, and identify knowledge gaps in our understanding of the overall climate system. \nWe invite contributions from all relevant disciplines and areas\, including observation (in stiu and remote sensing)\, modeling\, and theoretical research. \n\n  \nThemes to focus:\nTheme 1: Polar winter storms and climate impacts\, linking to\n\n\nExtreme event\n\n\nBlowing snow\n\n\nWarm air intrusion\n\n\nCold air outbreak\n\n\nSea ice evolution (open leads\, polynyas\, melt)\n\n\nAir-sea-ice interaction\n\n\nSurface mass balance for icesheet/iceshelf\n\n\nSurface energy budget\n\n\nPermafrost deepening\n\n\nAtmospheric boundary layer processes\n\n\nTheme 2:  Polar winter aerosol\, clouds and chemistry\n\n\n\nCCN\, INPs and sources\n\n\nAerosol budget and composition\n\n\nCloud-aerosol interaction\n\n\nArctic Haze\n\n\nSnow chemistry and climate impacts\n\nBiogeochemistry\n\n\nTheme 3:  Polar-mid-latitude and polar-lower-latitude teleconnections\, involving e.g.\n\n\nAtmospheric river\n\n\nPolar vortex\n\n\nJet stream\n\n\nStorm track\n\n\nAtmospheric blocking\n\n\nRossby wave\n\n\nTheme 4: Knowledge gaps to fill \n\n\nNew theory or mechanism and parameterisations\n\n\nNew technology observation (from buoys\, stations\, ships\, aircraft and satellites) active or automatic – via new international research programs\, e.g. IPY\, InSync\, etc\n\n\nNew modelling approaches\n\n\n \nKeynote speakers:\n\n\nOla Persson (CIRES/NOAA\, USA) on storm/sea ice\n\n\n\nMartin Radenz (TROPOS\, Germany) on aerosol/cloud remote sensing\n\n\nIrina Gorodetskaya (CIIMAR\, Portugal) on atmospheric river and Winter YOPP SH project\n\n\nTom Bracegirdle (BAS\, UK) on extremes and EXANT project\n\n\n\n\n\n\nWhen: 23-25 April 2025\nFormat: Hybrid\nWhere: British Antarctic Survey\, Cambridge\, CB3 0ET\, UK\nCost: free of registration – (Early Career Researchers can apply for travel fellowship)\nPlease register via using this link – Note that registration closes on [March 14 2025]\nPlease submit your abstract using this link – Note that abstract submission closes on [March 14 2025]\n\nOrganising Committee: \n\nXin Yang (Chair)\, BAS\, UK \nXiangdong Zhang (co-Chair)\, NCSU\, USA \nAlexandra Weiss\, BAS\, UK \nMarkus Frey\, BAS\, UK \nSergi González-Herrero\, WSL Institute\, Switzerland\nXianda Gong\, Westlake Uni.\, China\nRainette Engbers\, WSL Institute\, Switzerland\nRomy Hall\, BAS\, UK\n\n  \nWhat: This workshop is co-funded by the International Arctic Science Committee (IASC)\, Climate and Cryosphere (CliC) and Surface Fluxes in Antarctica (SURFEIT)\, a NERC National Capability International research programme. \nIf you have any questions\, please get in touch – Xin Yang – xinyang55@bas.ac.uk
