D03: Interactions between atmosphere and sea ice-ocean in the Arctic
The central aim of this project is to understand local feedback mechanisms between the atmosphere and sea ice-ocean in the Arctic, which are critical for Arctic amplification. Leads in sea ice will be investigated, which influence the heat and moisture exchange between the ocean and atmosphere. We will study their impacts on the atmosphere (heat and moisture fluxes, clouds, atmospheric circulation) and the oceanic mixed-layer sea-ice system. Leads are not uniformly distributed over the Arctic Ocean and have a different impact on the atmosphere depending on the time of the year. They are critical for the sea-ice formation in the cold season. New satellite data provide statistics about lead occurrence, Arctic wide, regionally, and for different seasons. Their characteristics and refreezing-rates will be compared within this project between model and observations. Furthermore, links to the dynamical variables (e.g., wind, ice drift) will be explored. Also, sea-ice roughness and its effects on the momentum, heat, and moisture transfer between both atmosphere and sea ice and atmosphere and ocean will be investigated. Particularly, the effect of different roughness length scales on the sea-ice dynamics will be evaluated. The study of atmosphere and sea ice-ocean interactions will include the influence of atmospheric circulation, in particular the role of synoptic cyclones. We will investigate, on the one hand, the storm-induced thermodynamic and dynamic responses of sea ice and the upper ocean and, on the other hand, the impact of Atlantic water inflow and ocean conditions on sea-ice and atmospheric changes. Ensemble simulations and dedicated sensitivity studies with the coupled regional atmosphere-ice-ocean model of the Arctic climate system HIRHAM–NAOSIM, linked with new satellite-derived data of Arctic-wide lead fraction and sea-ice surface roughness, will identify shortcomings in the process description. They will also help to understand associated regional feedback mechanisms, as well as the role of atmosphere-ice ocean interactions in Arctic amplification.
Regional feedback processes between atmosphere and sea ice–ocean associated with leads and cyclones are critical mechanisms for Arctic amplification.
Specifically we want to answer the following questions:
- How do sea-ice conditions (e.g., lead fraction, ice roughness) impact the air-ice/ocean momentum and energy exchange, and the atmospheric boundary layer and circulation?
- What is the role of the not yet fully understood cyclone – sea ice feedback mechanisms in Arctic amplification?
Achievements phase I
D03 achieved new data sets of sea-ice concentration (Lu et al., 2018), thickness, and snow depth on sea ice (Rostosky et al., 2018). Furthermore, the new coupled regional atmosphere-ice-ocean model HIRHAM-NAOSIM was upgraded with new model components, which include physical and numerical improvements and higher resolution, and a revised coupling (Dorn et al., 2018). Improved Arctic process descriptions (sea-ice drag and albedo) were implemented. An assessment of cyclone characteristics and the relation between atmospheric circulation anomalies (including intense storms) and sea ice was realised (Graham et al., 2019a; Semenov et al., 2019). Simulations with HIRHAM-NAOSIM have revealed a clear statistical relationship between summer sea-ice melt rate and atmospheric circulation (Rinke et al., 2019).
