The main aims of our Research group can be grouped as follow:
- The study of significant changes in relevant surface climatic variables (e.g. maximum and minimum temperatures, precipitation monthly averages and daily extremes);
- Assessment of major teleconnections (e.g. the North Atlantic Oscillation, the Scandinavian pattern or the Eastern Atlantic pattern) to characterize changes in the European climate.
- Development of tools to diagnostic the atmospheric circulation: circulation weather types (daily), cut-off low systems (COLs) and storm-tracking (several days), blocking events (up to 3 weeks).
- Development of statistical models and predictability studies at the monthly-seasonal range in the Atlantic-European region.
- Recovery of historical meteorological data from worldwide ancient archives and contribution to several international projects of historical reanalyses.
- Evaluation of different types of weather driven natural hazards: floods, droughts, landslides and heat waves. This objective and the corresponding achievements and output will be included in the Global Change and Societal Risks Research Line.
- Assessment of the impact of volcanoes, solar storms and variability on the Earth's magnetic field and climate. This objective and the corresponding achievements and output will be included in the Global Change and Societal Risks Research Line.
- Development of source separation techniques and measures, both of complexity and non-linear multivariate inter-relationships which are appropriate for non-Gaussian multivariate fields (e.g. the Sea Surface Temperature and Geopotential).
Within the framework of future warming scenarios projecting increases in the risk of more frequent heat waves and severity of rainfall extremes in regions of mid-high latitudes, it is of major importance to investigate the link of extreme events to atmospheric weather conditions. The research group has acquired a large experience in this topic, due to the enormous effort made in developing objective automatic methods to diagnose specific weather systems, such as weather types, extratropical cyclones and storm-tracks, blocking anticyclones, cut-off lows. The research group of Climatology and Climate Change is integrated in the Global Change and Societal Risks research line of the CGUL-IDL.
