Scientist and Education OfficerResearch Department, Earth System Modelling Section, Coupled Processes Grouppage tabs Profile Summary: I work at ECMWF as a Scientist and the Educational Officer. As a scientist I am working on introducing a thermodynamic-dynamic sea ice model to the coupled forecast system. This involves coupling and tuning the ice model within the ocean and atmospheric components of the model. I am interested in sea ice and its impacts on predictability. I am responsible for how the sea ice and SST analysis products that are used operationally at ECMWF for all our forecasting systems. We currently use the OSTIA SST and sea ice product. As the educational officer I help to organise the research department Numerical Weather Prediction training courses and I am also responsible for the research aspects of the web. Professional interests: Large scale modes of atmospheric variability Sea ice and it impact on predictability Coupled ocean-atmosphere processes Career background: I studied Physics at the University of Oxford, before going to the Meteorology Department at the University of Reading, where I completed my PhD: Climate variability: the effects of doubling carbon dioxide and uncertainty in model predictions. My main research areas have been on the impacts of large scale teleconnection patterns on various aspects of the climate system. I am currently interested in the impact of sea ice modelling in NWP and its impacts on predictability Scientist and Education Officer, ECMWF - responsible for the NWP training courses and coupled sea ice modelling (2011 - ) NERC Knowledge Exchange Fellowship (40/%FT position) - linking the financial services sector to weather and climate information, focusing in particular on how extended range forecasts could be used (2009-2011) Research Fellow, University of Reading - impact of resolution for seasonal forecasting and in particular on the NAO; Arctic climate change and the impacts of sea ice in the climate system (2007 - 2011) Senior Research Fellow, Climatic Research Unit, University of East Anglia - impact of Stratospheric Ozone depletion on surface climate (2006-2007) External recognitions: Fellow of the Royal Meteorological Society Member of the Institute of Physics Publications 2018 (2018) Dynamic sea ice in the IFS, ECMWF newsletter.
