AI003. Air-Sea Interaction at the Mesoscale and SubmesoscaleSession ID#: 22626 Session Description:Air-sea interaction has important coupled effects on the properties of the oceanic and atmospheric boundary layers, and the flux of momentum, heat, and other tracers between the atmosphere and ocean. For example, sea-surface temperature gradients at ocean fronts and eddies modify the surface wind field through changes in atmospheric boundary layer turbulence and pressure gradients. These changes in turn affect the evolution of the ocean boundary layer. Much of our understanding of these processes has been developed in considering the ocean mesoscale (horizontal scales of O(10-100 km)). However, recent advances in high-resolution numerical modeling, and future improvements in remote sensing, allow for consideration of ocean-atmosphere interaction at increasingly fine-scales, including the ocean submesoscale (O(100 m - 10 km)). Whether the mechanisms of mesoscale ocean-atmosphere interaction apply at the submesoscale, or whether other processes dominate, is an important open question. In this session we welcome contributions related to understanding air-sea interaction at the mesoscale and submesoscale, and how the mechanisms, and impacts, may depend on spatial scale. Contributions utilizing theory, observations, and numerical models are welcomed, as well as work focused on the impacts of coupled air-sea interaction on the physical or biogeochemical properties of the ocean or atmospheric boundary layers.

Ocean salinity and its role in ocean dynamics and the water cycleSession ID#: 29646 Session Description:This session highlights research investigating ocean salinity as a key parameter that links various elements of the water cycle to ocean circulation dynamics and climate. Contributions are invited on all aspects of ocean salinity investigations, including analyses undertaken from in situ and satellite observations, numerical models, and data assimilation. We particularly welcome contributions that have utilized sea-surface salinity (SSS) measurements from the recent pathfinder satellite missions (SMOS, Aquarius/SAC-D, and SMAP), as well as observations collected during the SPURS (Salinity Processes Upper-ocean Regional Study) experiment and other field campaigns. The session will focus on: recent progress from salinity remote sensing; new process-based insights from field observations; salinity-driven thermohaline circulation, upper-ocean stratification, and related ocean dynamics; links between salinity and global and regional climate variability; the water cycle, as well as the fingerprint of long-term change; salinity assimilation into ocean models; and the scientific imperative for future salinity measurement continuity and enhancement.

Role of oceans in tropical/extratropical air-sea interactionsSession ID#: 28128 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.

Southern Ocean air-sea exchange and mixed-layer processesSession ID#: 29747 Session Description:The Southern Ocean exchanges freshwater, momentum, heat, carbon and other biogeochemical species between the high-latitude ocean and atmosphere. These air-sea fluxes play important roles in the Earth’s climate system. Many observational and modeling efforts seek to quantify these fluxes and their dependencies. Uncertainties in Southern Ocean air-sea exchange remain high and limit our ability to validate climate models. Circumpolar transport, exchange along the continental margins, and meso-scale variability modify mixed-layer budgets, air-sea fluxes, and freshwater transport. Antarctic scientific stations facilitate long oceanic time series while autonomous platforms increase the geographic density of in situ observations. Models and satellite observations extend and connect observations to reveal underlying dynamics. Developments in observing approaches, data interpretation and numerical simulations offer new possibilities for advancing understanding in ways not previously possible. This session invites contributions that address surface flux estimates and mixed-layer processes in the Southern Ocean. Contributions addressing observing challenges, defining flux requirements, and/or presenting methodologies are welcome. We seek to bring together observers, modelers, and theorists.
