Abstract: In the 2013/14 winter, the eastern USA was exceptionally cold, the UK suffered severe flooding and the "Ridiculously Resilient Ridge" continued to bring drought to California. Studies have suggested that the tropics had an influence on these events, and I will review the evidence for this from observations and modelling, with a focus on the role of elevated sea surface temperatures in the tropical West Pacific. I will also discuss evidence for links between the North American and UK extreme weather.
If time allows, results from a more recent research project to produce a 50km-resolution GCM for use in large-ensemble simulations in order to study the impact of climate change on extreme weather events using the climateprediction.net
distributed computing architecture will be presented. The goal is to have a model that can both resolve synoptic weather features as well as state-of-the-art climate models and be cheaply run many hundreds of times to allow direct simulation of the most severe weather events.
