GOTHAM

GOTHAM

Globally Observed Teleconnections in a Hierarchy of Atmospheric Models (GOTHAM) is an international research project with partners around the globe funded JPI-Belmont Forum. Its central aim is to gain robust, relevant and transferable knowledge of past and present patterns and trends of regional climate extremes. This will be achieved by identifying the influence of remote drivers, also known as atmospheric teleconnections, on regional climate variability. GOTHAM aims to improve prediction in seasonal to decadal timescales using a combination of state-of-the-art climate models, citizen-science computing power and advanced statistical analysis tools.



Our contribution

Dim Coumou leads GOTHAM’s Work Package “Drivers behind anomalous mid-latitude flow linked to extreme weather in boreal summer and winter”. We study atmospheric teleconnections that have received little attention so far: Giorgia di Capua studies, in collaboration with partners from the Indian Institute of Tropical Meteorology, the 2-way interaction of the Indian Monsoon with the mid-latitude flow. Further, Efi Rousi, in collaboration with Stefan Rahmstorf, the role of the recent slowdown of the Atlantic circulation on recent weather extremes. We use a combination of observational data and climate model experiments and systematically apply machine-learning techniques (Causal Effect Networks, Self-Organizing Maps, etc.) to shed light on those aspects.




Summer school

In September 2017 we hosted a successful Summer School at PIK, with the aim of training young scientists on a unique combination of interdisciplinary scientific topics and tools relevant for understanding teIeconnections and their role in causing extreme weather events. The school comprised of lectures as well as tutorial sessions by some of the world’s leading experts in the field, both from GOTHAM partner institutes and external ones.
