The Earth System Physics (ESP) section studies a wide spectrum of the Earth system, from its fluid components (oceans and the atmosphere) to the planet's interior. The ESP section maintains a range of models and datasets and coordinates the Regional Climate research NETwork (RegCNET), encompassing over 600 participants worldwide.

Workshop on Indian Ocean Variability and Teleconnections | (smr 3592)
An ICTP Virtual Meeting
The focus of this workshop is the variability of the Indian Ocean climate and its teleconnections on sub-seasonal to multidecadal time scales during the boreal cold season. Observational and modelling studies address topics ranging from sub-seasonal predictability to inter-decadal trends.
At interannual time scales, the Indian Ocean hosts two important modes of variability: the Indian Ocean Basin Mode and the Indian Ocean Dipole. Both modes have two-way interactions with ENSO, but they may also exist independently. Through their influence on rainfall anomalies, they have important teleconnections to other tropical and extratropical regions. At sub-seasonal scales, atmospheric variability over the Indian Ocean is being widely investigated. Organized convection occurs in this region during the early phases of the MJO mode, producing global teleconnections. Furthermore, ENSO teleconnections to the Indian Ocean change on sub-seasonal timescales. At decadal timescales, the Indian Ocean shows important variability associated with a strong warming trend, which affects global decadal variability and regional climate change. Recent findings on these and related topics will be discussed at the workshop.
Topics:
• Teleconnections of Indian Ocean modes of variability with other tropical ocean basins
• Seasonal variations of ENSO teleconnections to Indian Ocean variability
• Tropical and extratropical teleconnections from Indian Ocean anomalies at intra-seasonal to decadal scales: similarity and differences across time scales
• Predictability arising from Indian Ocean teleconnections
• Impact of Indian Ocean warming trend on global climate

» Workshop on Indian Ocean Variability and Teleconnections | (smr 3592)
Earth system models attempt to represent the key processes that determine the climate of our planet, such as the atmospheric and ocean circulations, aerosols and atmospheric chemistry, biogeochemical cycles, the cryosphere, and land surface processes. The research of the group uses model tools such as the latest generation of the regional climate model REGCM and intermediate complexity global model SPEEDY to understand our climate, its natural variability and its response to anthropogenic forcings.
Climate extremes in the present day and in future decades can have severe implications, with the poorest members of societies being often the most vulnerable. The ESP group uses dynamical and statistical modelling techniques to assess the socio-economic impacts of climate
variability and change, for example on energy, water and health. As with the climate models, the dynamical impact models CHYM and VECTRI are made available to the wider scientific community through regular workshops and training events.
