SUMMARY:Polar and Subtropical Low-Level Clouds and Interactions with Aerosol Particles
DESCRIPTION:\nProf. Adele Igel\nDepartment of Land, Air, and Water Resources\nUniversity of California, Davis\nTuesday October 11, 2022, 2 PM ET\n\n \nAbstract:\nIn this seminar I will discuss my group’s work on the interaction of aerosols and low-level clouds in the\nArctic and in the subtropics. Aerosol concentrations are often exceptionally low in the Arctic boundary\nlayer, in fact, here we some of the lowest aerosol concentrations on Earth. I will discuss some of our\nrecent work about the implications on clouds of such low aerosol concentrations. On the other end of the\naerosol spectrum, many questions remain regarding the response of Arctic boundary layer clouds to\nincreasing aerosol concentrations which are expected as shipping lanes open due to increasingly little\nsea ice. We have been exploring the physical mechanisms that produce reductions in cloud liquid water\nwith an increase in aerosol concentration and find that they are strikingly different from mechanisms in\ntheir subtropical cousins. The physical mechanisms will be discussed for clouds in both regions.\n \nBiosketch:\nAdele Igel is an Associate Professor of Cloud Physics at UC Davis and is currently serving as Editor for\nthe Journal of the Atmospheric Sciences. She earned her M.S. and Ph.D. degrees at Colorado State\nUniversity. She has a range of research interests including microphysics parameterizations, low clouds\nand fog, and convection. She’s steadily moved from east to west across the country and has discovered\nthat she much prefers living in low humidity locations with easy access to mountains!\nWebinar:\nEvent site: https://go.umd.edu/igel ( https://go.umd.edu/igel )\nZoom Webinar: https://go.umd.edu/igelwebinar ( https://go.umd.edu/igelwebinar )\nZoom Meeting ID: 936 8725 4921\nZoom password: essic\nUS Toll: +13017158592\nGlobal call-in numbers: https://umd.zoom.us/u/aMElEpvNu ( https://umd.zoom.us/u/aMElEpvNu )\nFor IT assistance:\nCazzy Medley: cazzy@umd.edu\nResources:\nSeminar schedule & archive: https://go.umd.edu/essicseminar ( https://go.umd.edu/essicseminar )\nSeminar Google calendar: https://go.umd.edu/essicseminarcalendar ( https://go.umd.edu/essicseminarcalendar )\nSeminar recordings on Youtube: https://www.youtube.com/user/ESSICUMD ( https://www.youtube.com/user/ESSICUMD )\n
