1. What is the impact of Arctic climate change on mid latitudes through atmospheric and oceanic linkages?
To determine the impact of Arctic climate change on the Northern Hemisphere mid-latitudes, a set of coordinated multi-model experiments will be carried out within the project. The sensitivity of the response to the background flow and the regional distribution of ice anomalies will be explored, and atmospheric and oceanic pathways for polar-mid-latitude linkages will be identified. The linkages will be studied from a prediction perspective.
2. How is it possible to observationally constrain weather forecasting models using advanced metrics and diagnostics?
The project aims to develop a set of metrics and diagnostics that target key processes in the Arctic atmosphere, sea ice and ocean as well as user-relevant information. We apply these tools to assess the realism of both existing models (baseline) and improved models developed during the project, to make advanced metrics and diagnostics available in the Earth System Model eValuation Tool (ESMValTool, Eyring et al. 2015). In this way we can explore the concept of emergent constraints in the Arctic for narrowing the uncertainty of regional climate change projections.
5. How can APPLICATE enhance the capacity to predict Northern Hemisphere weather and climate?
The existing prediction systems are first analysed. Afterwards, when models are improved as project task, the impact of enhanced models and initialization strategies are evaluated against the initial analysis. As a result of this comparison, we are then able to provide recommendations for the advancement of forecasting systems fort the Arctic and Northern Hemisphere.
7. How will the knowledge generated through APPLICATE be transferred to stakeholders, including the raining of early career scientists?
APPLICATE aims to establish an effective dialogue with key stakeholders. Stakeholder engagement aims to disseminate the project results widely, but also to exploit means such as project and data portals through international frameworks (WMO, ICSU, SAON etc.), to implement enhancements in operational prediction systems and transition into Copernicus services (C3S), to involve partners from both weather and climate communities, and to develop a training programme in collaboration with the Association of Early Polar Career Scientists (APECS)
