Regional Influence of Solar Variability on European Climate — •Katja Matthes — GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel — Christian-Albrechts-Universität zu Kiel

Solar variability related to irradiance and energetic particle forcing could be an important source of natural climate variations superimposed on the human-induced warming since the late twentieth century in particular on the regional scale. Because of its prominent 11-year cycle, solar variability offers a degree of predictability and could potentially enhance decadal scale predictions. Understanding the influence of solar variability on climate requires knowledge of solar variability, solar-terrestrial interactions and observations, as well as mechanisms determining the response of the Earth's climate system.

The talk will summarize our current understanding of the impact of solar irradiance and energetic particle forcing on the atmosphere with special focus on the regional changes over the North Atlantic and Europe from observational and modeling studies. We will present feedback mechanisms for the solar signal transfer and discuss the importance of the solar cycle for decadal climate predictions.
