Her seminar is entitled ?From aerosol activation to global albedo trends: How clouds shape Earth?s climate? (abstract below) DATE: Tuesday, January 13 TIME: 3-4 PM LOCATION: EOA 1044 SPEAKER: Dr. Clare Single TITLE: From aerosol activation to global albedo trends: How clouds shape Earth?s climate ABSTRACT: Earth?s climate is, to first order, determined by the balance of incoming solar radiation and outgoing infrared radiation. I will focus on the shortwave, where clouds and aerosols are fundamental in setting the planetary albedo. However, the processes that control the distribution of clouds and the albedo of the clouds themselves span a dozen orders of magnitude in scale, from aerosol activation (micrometers), to boundary layer turbulence (meters), up to the global distribution of cloud regimes set by the large-scale atmospheric circulation (100s of kilometers). My work spans a wide range of topics, where the aim is to understand how clouds radiatively shape climate and climate changes. To tackle this range of scales, I use a similarly wide range of models and observations that are each fit for purpose. In this talk I will highlight three examples from my work that fill in this hierarchy of scales and process complexity. Starting at the global scale, I will discuss the recent observed trend of decreased global reflectivity and its hemispheric asymmetry and show that an important contribution to this has been an increase in sea spray aerosol emission over the Southern Ocean. Jumping to smaller scales, I will give an example of how we can build a conceptual model of boundary layer clouds to explore the robustness and sensitivity of CO2-induced stratocumulus cloud breakup. I will discuss the connection to climatological cloud regime transitions, cloud feedbacks, and proposed future deliberate cloud interventions. Finally, at the very smallest scales, I will show how we can use a new class of particle-based cloud microphysical models to bridge from novel laboratory measurements of secondary organic aerosol to climate-relevant impacts on cloud albedo. Lastly, I will conclude with a discussion of my future research directions. We look forward to seeing you there! Ming Cai -------------- next part -------------- An HTML attachment was scrubbed...

What drives the temperature variability in the Gulf of Maine? By Yueyang Lu Description: Over recent decades, the Gulf of Maine (GoM) has experienced warming rates exceeding 99% of the global ocean, causing profound consequences for regional marine ecosystems and fisheries. While the GoM temperature variability is traditionally attributed to the warm Gulf Stream waters, cold Labrador Slope waters, and air-sea fluxes, a quantitative understanding of these drivers has remained unknown, especially over different timescales. Using a high-resolution numerical simulation that accurately reproduces the observed GoM temperature changes, this study demonstrates that the ocean heat transport (OHT) and air-sea heat flux have inverse influences on the GoM temperature variability across non-seasonal timescales. On interannual and longer scales, the OHT precedes air-sea heat flux by approximately 5-10 months, with the latter partially offsetting OHT im-pacts through SST feedback. Furthermore, the OHT shows a strong correlation with the meridional displacement of the Gulf Stream, whereas the along-shelf transport of the inshore branch of the Labrador Current exhibits a weaker correlation with the OHT. These results suggest that the Gulf Stream shift plays an important role in driving temperature changes within the GoM, while the in-fluence of Labrador Current is secondary Celebrating 20 Years of SAMOS! By Shawn Smith Description: Presentation will revisit the history of the SAMOS initiative, how the project came to be, where SAMOS is today, and the vision for the future. Several unique events from the past 20 years will be highlighted. NOTE: Please feel free to forward/share this invitation with other groups/disciplines that might be interested in this talk/topic. All are welcome to attend. -------------- next part -------------- An HTML attachment was scrubbed... URL: -------------- next part -------------- A non-text attachment was scrubbed...
