[Eoas-seminar] MET Seminar: Tuesday November 18 3 PM - Prof. Talia Tamarin-Brodsky (MIT)

[eoas-seminar at lists.fsu.edu]

Dear all,

While we prepare for the Baum lecture this Friday, we are also looking ahead to our next Meteorology seminar, which is next Tuesday November 18 at 3 PM, given by Professor Talia Tamarin-Brodsky<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftaliatamarin.wixsite.com%2Ftaliatamarin&data=05%7C02%7Ceoas-seminar%40lists.fsu.edu%7Cc6a53766d16940c7899708de2228c70a%7Ca36450ebdb0642a78d1b026719f701e3%7C0%7C0%7C638985755678382252%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=uJuxgZDlIQmPiPMIEfhmNH7fHdkjRftWYiJEQ6LtjLU%3D&reserved=0> from MIT. She will present "On storm tracks, weather regimes, and a wave breaking recipe” (abstract below).

Prof. Tamarin-Brodsky will present in person in EOA 1044, but a zoom link is available for those with approved work off-campus or a medical excuse. Please contact Allison Wing (awing at fsu.edu<mailto:awing at fsu.edu>) for the Zoom link.

She is available for meetings on Tuesday with faculty/students; please contact Allison Wing if you are interested in meeting. Prof. Cai and I will also take her for snacks and drinks at Proof at the Union immediately after the seminar - please join!

DATE: Tuesday November 18
TIME: 3-4 PM, please join early for refreshments
LOCATION: EOA 1044
SPEAKER: Prof. Talia Tamarin-Brodksy<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftaliatamarin.wixsite.com%2Ftaliatamarin&data=05%7C02%7Ceoas-seminar%40lists.fsu.edu%7Cc6a53766d16940c7899708de2228c70a%7Ca36450ebdb0642a78d1b026719f701e3%7C0%7C0%7C638985755689618933%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=HZ3v%2BHyhywU4EsjQhVKNswuf8E8YVU4RUfFlGY7xjgA%3D&reserved=0>

TITLE: On storm tracks, weather regimes, and a wave breaking recipe

ABSTRACT: The atmospheric circulation is often decomposed into high- and low- frequency variability. For example, the low-frequency variability in the North-Atlantic includes slowly varying weather regimes such as the North Atlantic Oscillation, with timescales of weeks. The high frequency variability includes the synoptic weather systems, which shape our daily weather fluctuations. The interaction among these timescales is often mediated by Rossby Wave Breaking (RWB) events, which involve the irreversible breaking and dissipation of the baroclinic waves. To investigate this interaction, a simple RWB recipe is derived by exploring which processes contribute to a meridional overturning of high-frequency PV contours. A picture emerges in which the slowly varying weather regimes influence the tracks of high-frequency systems, which in turn, depending on the position relative to the low-frequency flow, determines whether the frequency of RWB (cyclonic or anticyclonic) is enhanced or suppressed. The recurrence of same-type RWB in a similar position then shapes the overall mean structure of the weather regime.

We look forward to seeing you there!
