COCOA kicks off

13 February 2017

The ANR funded project COCOA has held its kick-off meeting on January 25-28 2017 in Gresse-en-Vercors. This gave scientists from the various disciplines involved in the project (climate modelling, air-sea interface modelling, applied mathematics, computer science, etc.) the opportunity to gather and discuss the different aspects of the project. COCOA, which stands for "COmprehensive Coupling approach for the Ocean and the Atmosphere”, aims to improve climate simulations with a better physical representation of ocean-atmosphere coupling processes.

EU Project APPLICATE kicks off

17 November 2016

EU Horizon 2020 Project Studying Arctic's Connections to Weather and Climate in Europe, Asia and North America Kicks Off Bremerhaven, 14 November 2016. An EU-financed project investigating ways to improve weather and climate prediction in the face of a rapidly changing Arctic officially started this month. Known as APPLICATE (Advanced Prediction in Polar regions and beyond: modelling, observing system design and LInkages associated with a Changing Arctic climaTE), the €8 million project, financed by the EU HORIZON 2020 Research and Innovation programme, involves 16 partners from nine countries (Belgium, France, Germany, Iceland, Norway, Russia, Spain, Sweden and the United Kingdom) and will be carried out over a period of four years. The multinational and multidisciplinary consortium will work to enhance weather and climate prediction capabilities not only in the Arctic, but also in Europe, Asia, and North America. A focus on the Arctic is important for improved predictions of weather and climate in the midlatitudes because the changes taking place in the Arctic due to climate change—the retreat of sea ice, ice loss from the Greenland Ice Sheet and other ice caps, warming seas and a warming atmosphere—have the potential to influence weather and climate in the mid-latitudes. According to several studies (the most recent of which was published in Nature Climate Change in October 2016), a warming Arctic can, in fact, lead to prolonged periods of severe weather and cold spells in the mid-latitudes. The impacts of severe weather on commerce and infrastructure can be significant, so having adequate tools to predict when and how severe weather systems will affect Europe, Asia and North America is vital to inhabitants of these regions. The APPLICATE project is bringing together an international team of experts in weather and climate prediction to improve climate and weather forecasting models to work on improving prediction tools while expanding and improving observational capabilities in the Arctic. “In the Arctic, today’s prediction systems suffer from a lack of observations, model shortcomings and deficits in effectively combining models with observations,” according to APPLICATE Project Coordinator Prof Thomas Jung, climate scientist at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, the lead partner in the project. “Our aim is to design a future Arctic observing system that enhances our predictive capacity. Additionally, the representation of critical processes in models will be improved and new ways of assimilating observations into models will be explored.” The APPLICATE project also involves a strong education, training and outreach component in order to train the next generation of experts and raise awareness about the benefits of improved climate and weather forecasting. Members of the APPLICATE consortium will engage with stakeholders who use weather and climate forecasts in hopes of receiving constructive feedback, allowing the models and forecasts to be constantly improved and updated, taking into account user needs. Early career scientists in climate-related fields will have the opportunity to participate in a summer school and webinar lectures, while the general public will be able to learn about the project thanks to specially-produced informational videos and publications. Consortium members plan to work closely with other EU-financed projects and researchers outside of Europe working on similar topics in order to maximise synergies and productivity. A website for the APPLICATE project offering regular news and information about the initiative is set to be launched in the coming months. Read more
