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

The My Climate Risk (MCR) – Ateneo de Manila University (ADMU) Regional Hub, through the Ateneo Institute of Sustainability, invites you to the first of two online webinar series, “Climate Voices on the Ground: Perspectives from Different Sectors”, which seeks to foster discussion on the contexts and experiences of climate change among different communities and stakeholders.

In this series, the perspectives of community-based organizations, coastal and small island communities, and microenterprises will be highlighted. The discussions will revolve around how they make sense of their experience of climate change and what their climate information needs are.

The webinars will occur on three successive Fridays of October 2022: on the 14th, 21st, and 28th, each from 4:00-5:30 PM (Philippine Time) or 8:00-9:30 AM UTC. We invite all interested parties to register at linktr.ee/MCR_ADMU.
