Understanding the impact of teleconnections on extreme weather events

Understanding the impact of teleconnections on extreme weather events

The Centre’s Associate Professor David Wallom and climateprediction.net Applications Coordinator Dr Sarah Sparrow will train attendees in data management skills and give an introduction to using CPDN (climateprediction.net) within scientific experiments at the GOTHAM International Summer School this month.

Organized by the Potsdam Institute for Climate Impact Research (PIK), the GOTHAM Summer School (18th-22nd September 2017) will train over 25 young researchers a unique combination of interdisciplinary scientific topics and tools relevant for understanding global teleconnections and their role in causing extreme weather events.

Teleconnections are defined by the American Meteorological Society as "a linkage between weather changes occurring in widely separated regions of the globe". Professor Wallom and Dr Sparrow work on the climateprediction.net project (CPDN), which runs climate models on thousands of individual home and work computers to help answer questions about how climate change is affecting our world, now and in the future.

GOTHAM is a new project funded by NERC (Natural Environment Research Council) that aims to identify the relative impact of different teleconnections on regional climate and extreme weather events. Professor Wallom is co-Investigator on the project.

The school, this year themed on Global Teleconnections in the Earth's Climate System – Processes, Modelling and Advanced Analysis Methods, comprises lectures as well as tutorial sessions by some of the world's leading experts in this field. Professor Wallom and Dr Sparrow will be training attendees on data management skills along with how to use CPDN within their scientific experiments.

Specific topics include:
• Global consequences of extreme El Niños
• Mid-latitude weather extremes and the role of tropical, extratropical and Arctic drivers
• Stratosphere dynamics and stratosphere-troposphere interactions
• Internal variability and external drivers of South and East Asian monsoon systems.
• Interactions between global teleconnection patterns
• Data management skills and the use of citizen science platforms (climateprediction.net)
• Identification of teleconnections using complex systems or network methods.
