[eoas-seminar at lists.fsu.edu]

Dear all,

Please join us next Thursday February 15 for a Meteorology seminar given by Prof. Cameron Homeyer<http://homeyer.oucreate.com/> (University of Oklahoma). He will speak about "How are Thunderstorms Changing the Stratosphere? Evidence from Recent Airborne Observations"

Prof. Homeyer will be joining us in person and is available for meetings on Thursday. Please contact Allison Wing (awing at fsu.edu<mailto:awing at fsu.edu>) if you would like to meet with him.

Graduate students are invited to join for a free pizza lunch with the speaker at 12:30 PM - please RSVP to Allison Wing.

Faculty are invited to join for drinks and casual conversation immediately after the seminar at Proof at the Union.

DATE: Thursday February 15
SEMINAR TIME: Refreshments at 3 PM, Talk 3:15 - 4:15 PM
SEMINAR LOCATION: EOA 1044 (Speaker in person)
SPEAKER: Prof. Cameron Homeyer<http://homeyer.oucreate.com/>

TITLE: How are Thunderstorms Changing the Stratosphere? Evidence from Recent Airborne Observations

ABSTRACT: The recently-completed deployments of the Dynamics and Chemistry of the Summer Stratosphere (DCOTSS) field campaign during the summers of 2021 and 2022 resulted in extensive sampling of stratosphere air impacted by tropopause-overshooting convection (thunderstorms). DCOTSS was based out of Salina, Kansas in the central United States, near the climatological maximum in overshooting. Unprecedented evidence of extreme stratospheric hydration by convection was observed and reached altitudes up to 4 km above the tropopause and potential temperatures in excess of 450 K. Such hydration (and transport of additional greenhouse gases) is important to radiative forcing of Earth’s climate, as it can exacerbate observed warming. In this talk, I will provide a summary of the DCOTSS observations, highlight unique insights from a case study where active overshooting convection was sampled, and demonstrate how DCOTSS trace gas observations can be used to improve understanding of important constraining processes.

We look forward to seeing you there!

Cheers,

Allison
