With a diminishing sea ice cover\, surface heat fluxes are modified\, with expected implications for the temperature inversion a nd related climatic features such as Arctic haze mixing in the boundary la yer\, cloud formation and the lapse-rate feedback\, among others. In this study\, we use the Community Earth System Model (CESM) Large Ensemble (Kay et al. 2014) to study projected changes in temperature inversion in respo nse to changes in sea ice cover. We find a strong seasonal signal\, with s ignificant decreases and increases in temperature inversion strength durin g the winter and summertime\, respectively. Wintertime decreases are shown to be linked to a decrease in sea ice thickness\, whereas summertime incr eases are related to atmospheric warming in regions of ongoing sea-ice mel t.\n DTSTART:20151028T183000Z DTEND:20151028T190000Z LOCATION:Room 934\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Student Seminar: Line Bourdages URL:/meteo/channels/event/student-seminar-line-bourdag es-255056 END:VEVENT END:VCALENDAR
