Trace Gas Transport in the Stratosphere: Opportunities and Challenges

Published:

The transport of trace gases through the stratosphere impacts surface climate. Small changes in stratospheric water vapor, on the order of one part per million, can impact surface temperature by as much as a tenth of a degree. A sudden drop in stratospheric water vapor of this magnitude – a response to internal variability of the atmosphere – was observed in 2000. Chemistry climate model simulations of stratospheric ozone also depend critically on the transport of ozone and ozone depleting substances, and biases in transport are a leading source of uncertainty in the recovery of stratospheric ozone. Volcanic aerosols (and the possibility of injecting sulfur into the stratosphere for climate intervention) provides another example of the importance of stratospheric tracer transport for the climate at the surface.

Downward migration of the zonal-mean circulation in the tropical atmosphere

Published:

The annular modes of the extratropical atmosphere have received much attention for quantifying and predicting variability of the jet streams and storm tracks, despite the limited zonal coherence of midlatitude variability. In the tropics, annular Huctuations of the circulation have not been investigated, despite the comparative dominance of zonal-mean variations in this region, associated with weak temperature gradients at low latitudes.

Downward Migration in the Zonal Mean Circulation of the Tropical Atmosphere

Published:

This is my first ever virtual colloquium visit. From the comforts of my own office, I’ll present my talk over the internet, coupled with a day of virtual meetings with students, postdocs, and faculty. The goal is to reduce our CO2 footprint – something our field should mindful of more than any other – but it will also help reduce the “family footprint”, i.e. the impact on spouses left to deal with kids who tend to get sick this time of year. Ugh. Only catch is that the seminar is 3:30 pm on a Friday, Pacific time!

Generalization and Calibration: A 1-D QBO model testbed for data-driven gravity wave parameterization

Published:

I attended this meeting virtually, actually tuning in from three different locations. In a classic, left hand doesn’t know what the right is doing, I managed to schedule our moving date to Berlin to coincide with my talk! It only worked out in the end because our sessions were in the late afternoon in Pittsburgh, so I could join our sessions at 10 pm. It started on the last day of our vacation in Tuscany, then I was in Bayreuth for the second day, as we paused on our drive across Europe, reaching Berlin for the final day of the symposium when I gave my talk!

Revealing the statistics of extreme sudden stratospheric warming events hidden in short weather forecast data

Published:

A ‘solicited’ talk at the 2023 EGU Meeting at a session on the middle atmosphere. Hmm, sounds a bit sketchy in American English, where solicited usually comes up in a legal context! I’m taking it as an opportunity to show Justin Finkel’s methods to extract climatological statistics from S2S data. This is joint work with Dorian S. Abbot and Jonathon Weare.

Revealing the statistics of extreme sudden stratospheric warming events hidden in short weather forecast data

Published:

To round out my sabbatical, an invited talk at the 2023 International Union of Geodosy and Geophysics General Assembly. Fitting that the meeting is in Berlin! As in Vienna, I’m taking it as an opportunity to show Justin Finkel’s methods to extract climatological statistics from S2S data to an audience of atmospheric scientists. This is joint work with Dorian S. Abbot and Jonathon Weare.
