An important aspect of climate research, concerned with climate dynamics, involves the study of large-scale phenomena, processes, and mechanisms of climate variability and change on seasonal to centennial time-scales. Climate dynamics should provide the basic concepts, terminology, and phenomenological explanation that can be used to characterize regional to hemispheric climate variability and change. A common way of studying climate dynamics is to define ‘modes’ of variability that may be described in statistical and/or physical terms. Such modes may influence climate outside their region of existence via remote teleconnections. Interest in climate dynamics is growing as the quantity and quality of new observational datasets and numerical modeling outputs are increasing. Yet, the understanding of climate dynamics has not yet been extensively applied in new research areas such as long-term regional climate change assessment.
The overarching Panel obective is to advance our basic understanding of atmosphere-ocean climate dynamics using observations and models and to determine the role of climate dynamics in shaping climate variability and change on seasonal to centennial time scales. Specific activities will, in the first instance, be organized around three areas
- the organisation of storms, blocks and jet streams on seasonal and longer time scales,
- ocean basin to ocean basin and tropical-extratropical teleconnections,
- the development of predictive theories of climate dynamics.
