Work Packages



Work package 1: Improving seasonal long-range forecast skill of risks for hazardous weather and climate events.

Extreme weather events such as storms, heat waves, floods and droughts can have a devastating impact. Climate change increases the likelihood of these events, but because they are so infrequent, they are very difficult to predict. This work package explores specialised statistics such as extreme value theory to improve our predictions of these events. It also explores whether the probability of extreme events, such as polar lows, can be related to larger scale meteorological events, such as marine cold air outbreaks. The work done in this work packages is closely related to the Opens internal link in current windowshipping case study.

Work package 2: Lower latitude drivers of Arctic changes.

Warming in the Arctic is affected by warm ocean waters travelling from lower latitudes, but the mechanisms are not well understood. This work package uses data from international ocean observing systems, from underwater gliders to Argo profiling floats, that measure the salinity and flow of the water. These data are used to improve simulations of how heat and freshwater transfer occurs from subpolar gyres to the Arctic regions. This work package also identifies gaps in our current ocean observing systems, and provides feedback on the volumes of data required for accurate modelling.  


Work package 3: Linkages of Arctic climate changes to lower latitudes.

The warming Arctic causes changes in the ocean and atmosphere that can influence the weather and climate of lower latitudes. This work package investigates the potential effects of these changes, through state-of-the-art ocean, atmosphere or coupled models. Atmospheric models study the interplay between Arctic warming, the polar vortex, the jet stream and atmospheric planetary-waves. Ocean models study the release of freshwater from melting sea ice and the effect on ocean circulation, such as the Atlantic Meridional Overturning Circulation (AMOC).

Work package 4: Enhancing the capacity of seasonal-to-decadal prediction in the Arctic and over the Northern Hemisphere.

A key aim of many climate models is to be able to predict future climate. This work package involves making assessments of the processes underlying the linkages between the Arctic and lower latitudes, and their representation in current prediction systems. The aim is to develop more advanced statistical bias correction and calibration techniques to enhance predictability of climate and extreme weather events in the Northern hemisphere.

Work package 5: Developing and valuing climate and information services.

Often the outputs from climate models are difficult to understand and put to use for individuals and small businesses. This work package works with stakeholders to codesign methods of translating outputs from climate models into useable products. These is highlighted through a series of Opens internal link in current windowfive specific case studies, covering sectors as diverse as tourism, mortality, shipping, fisheries and sustainable economic development. This work package also brings together the lessons learned from each case study to identify the need for future climate services.

Work package 6: Clustering.

Blue-Action has established a strong clustering activity with the European and international scientific communities focussing on climate services, Arctic impacts, Blue Growth. This work package supports the  exchange and interaction between the products and services that Blue-Action delivers and the Communities focusing on those themes. The goals of this work packages are to identify open research questions/development needs, to create synergies between these projects, to share knowledge and support knowledge transfer. A number of workshops and interactions are regularly organised with the EU Climate Modelling Cluster, the EU Arctic Cluster and the Climate Service Cluster.
