Workpackage 4.2: Mechanisms of regional-scale change and the impact of climate change on natural climate variability

Leader: Silvio Gualdi (INGV, Intituto Nazionale di Geofisica e Vulcanologia)

Objectives: To study the mecahnisms to assess the regional features of climate change, including changes that may result from a modification of the patterns of natural variability.

Task 4.2a: Study the low-frequency variability of the meridional overturning circulation (MOC) in the coupled integrations performed within the PREDICATE project. Design and set up a set of coordinated time-slice experiments to study the role of land-ocean contrasts and ENSO.

Task 4.2b: Validation and use of the Ensemble System Models to study interannual variability in long multi-century experiments or large ensembles of multi-decadal experiments. Study of the 11-year solar cycle and its impacts on the climate system.

Task 4.2c: Study the processes responsibles for regional climatic variability in key areas (Indian Ocean, ocean heat uptake areas).
