Join us for a webinar on cloud feedbacks and atmospheric dynamics from the latest series on tipping elements, irreversibility, and abrupt changes in the Earth system from the WCRP Lighthouse Activity on Safe Landing Climates, AIMES, the Earth Commission, and Future Earth. It will take place on 23 November, 10:30 – 12:00 CET.
Our two speakers are Caroline Muller (Institute of Science and Technology Austria) who will talk about the spontaneous aggregation of convective storms and Rodrigo Caballero (Stockholm University) who will discuss the transition to superrotation in warm climates. The webinar will be moderated by Steven Sherwood (The University of New South Wales).
To register, please see the event website.

The WCRP Explaining and Predicting Earth System Change Lighthouse Activity invites you to join the second webinar of the series that will provide a discussion forum on topics focused on predicting and explaining a range of different climate phenomena and events, while supporting the further development of a scientific agenda.
This second webinar will focus on the Triple La Niña and will provide a view of causes, key processes and prediction of such event.
SPEAKERS:
The event will take place on 22November 2022, from 15:00hs to 16:30hs UTC. Speakers will give a 20-minute talk each followed by a round table discussion, with questions from participants.

The DynVar and SNAP activities are going to hold a joint meeting in Munich in October 2023:
The Role of Atmospheric Dynamics for Climate and Extremes
9-13 October 2023 at the Meteorological Institute at Ludwig-Maximilians- University Munich, Germany
Scientific Program
• Links of atmospheric circulation to weather and climate on subseasonal to centennial timescales
• The role of stratosphere-troposphere coupling in predictability of tropospheric climate and surface weather extremes
• The influence of climate model biases on uncertainty in predictions and projections
• Emerging dynamical constraints to understand and reduce projection uncertainties
• Mechanistic understanding of dynamic coupling, teleconnections, and trends
We anticipate travel support for early career scientists and
attendees from developing nations.
Deadlines will be announced in early 2023
