Climate Modelling
A hierarchy of climate models with increasing complexity from simplified atmosphere to global coupled atmosphere-ocean-ice models is used to identify the signals of natural variability and to understand the influence of large-scale dynamic variability connected with the natural circulation modes of the global climate system and the regional feedbacks involved in the complex Arctic atmosphere-sea-ice-ocean-land system.
