Europe/Rome
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
