AI53A:
Role of Oceans in Tropical-Extratropical Air-Sea interactions II


Session ID#: 36686

Session Description:
Oceans play an important role in setting the variations of climate in tropical and extratropical regions. The Air-sea interactions in the tropics, such as El Nino-Southern Oscillation (ENSO), Indian Ocean Dipole (IOD) and Atlantic Nino, influence the weather and climate not only in the tropics but also in the mid- and high latitudes through teleconnections. However, these tropical-extratropical interactions are not always captured by global climate models. In fact, this is one of the major reasons for model biases leading to low-level of predictability in seasonal to interannual climate variations of extra-tropics. In addition, air-sea interactions, in the mid- and high-latitude regions, including the interactions with sea-ice, remain a topic of active research. Those are especially active in oceanic fronts and meso-scale eddies and are not well represented in global models. This session seeks to bring together observational and modeling studies that investigate air-sea interaction, global teleconnections, ocean data assimilation and their impacts on climate predictions.
