APPLICATE: Advanced Prediction in Polar regions and beyond: Modelling, observing system design and


Arctic climate change increases the need of a growing number of stakeholders for trustworthy weather and climatepredictions, both within the Arctic and beyond. APPLICATE will address this challenge and develop enhanced predictivecapacity by bringing together scientists from academia, research institutions and operational prediction centres, includingexperts in weather and climate prediction and forecast dissemination.

APPLICATE will develop a comprehensive frameworkfor observationally constraining and assessing weather and climate models using advanced metrics and diagnostics. This framework will be used to establish the performance of existing models and measure the progress made within the project. APPLICATE will make significant model improvements, focusing on aspects that are known to play pivotal roles in bothweather and climate prediction, namely: the atmospheric boundary layer including clouds; sea ice; snow; atmosphere-seaice-ocean coupling; and oceanic transports.

In addition to model developments, APPLICATE will enhance predictive capacityby contributing to the design of the future Arctic observing system and through improved forecast initialization techniques.The impact of Arctic climate change on the weather and climate of the Northern Hemisphere through atmospheric andoceanic linkages will be determined by a comprehensive set of novel multi-model numerical experiments using both coupledand uncoupled ocean and atmosphere models.

APPLICATE will develop strong user-engagement and disseminationactivities, including pro-active engagement of end-users and the exploitation of modern methods for communication anddissemination. Knowledge-transfer will also benefit from the direct engagement of operational prediction centres in APPLICATE. The educational component of APPLICATE will be developed and implemented in collaboration with theAssociation of Early Career Polar Scientists (APECS).
