QBOi – SNAP – QUOCA (QSQ) joint workshop
Improved simulations of the stratosphere for better predictions of
weather, climate and extreme events
A joint QBOi – SNAP – QUOCA (QSQ) workshop
24-28 March 2025, Cambridge, UK
The workshop’s purpose will be to facilitate the sharing and discussion of the latest results on the role of the stratosphere in models relevant for enhancing predictability on all timescales. The workshop will serve as the in-person kick-off for the new QUOCA (QUasi-biennial oscillation and Ozone Chemistry interactions in the Atmosphere) joint QBOi-CCMI project. The aim of the workshop is to better understand stratospheric processes and variability, uncertainties, and their influence on surface climate and predictability.

33rd APARC SSG Meeting 2024
28 – 30 October 2024
Forschungszentrum Jülich, Germany
General Information
The next APARC SSG meeting will be held at the Forschungszentrum Jülich from 28 to 30 October 2024. Unfortunately, Jülich is a small town with a limited number of hotels and leisure activities and is difficult to reach by public transportation. That’s why we decided to ask you to book your hotel in Aachen. Aachen is well connected by train to several nearby airports. Düsseldorf, Cologne, Brussels and Frankfurt are possible destinations. We will arrange daily bus transfers from Aachen to Jülich in the morning and from Jülich to Aachen in the evening. We also plan to have a common dinner together in Aachen on Tuesday evening. In addition, Aachen has an old city center with a beautiful cathedral, many restaurants, and is always worth a visit if you have some free time.
We will hold this meeting as a hybrid meeting. If you are unable to travel, you will have the opportunity to participate online.

QBO@60 webinar series
In lieu of the QBO@60 workshop in July 2021, an online seminar took place on 6 July 2021 that featured two invited talks celebrating the discovery of the QBO. The invited speakers were Kevin Hamilton and Mike Wallace.
The recording of the seminar can be found here.
The discovery of the QBO and related developments, 1883-1961
Kevin Hamilton, International Pacific Research Center, University of Hawai`i at Mānoa
In the last months of 1883 a global sensation was spawned by the sudden appearance of spectacular sunrises and sunsets throughout the world (e.g. see Simon Winchester’s 2003 bestseller “Krakatoa – the Day the World Exploded”). The effort to demonstrate the connection between the colorful twilight phenomena and the […]
