Many aspects of atmospheric-ocean interactions at high southern latitudes are still poorly understood. For instance the interaction of large cyclonic and mesoscale storm systems with the atmospheric moisture balance in a changing climate and with a warming ocean are curiously different from the corresponding Arctic case.This project seeks to better quantify the contribution of water vapor transport, and especially the mesoscale drivers of synoptic variability, on the surface mass balance of the Antarctic ice sheets, and also to the annual progression of Southern Ocean sea-ice. To investigate the role of these mesoscale cyclonic storm systems, a variety of satellite data products, best available reanalysis products and the Weather Research and Forecasting (WRF) model predictions will be used to developed scenarios for changes in cyclone frequencies and strength in an intensifying hydrological cycle, and the impacts these may have on Antarctic sea-ice and continental surface mass balances.

高南部纬度的大气 - 海洋相互作用的许多方面仍然对此知之甚少。例如，在气候变化和温暖的海洋中，大型气旋和中尺度风暴系统与大气水分平衡的相互作用与相应的北极案件奇怪不同。该项目旨在更好地量化水蒸气运输的贡献，尤其是在共同质量的质量变化的范围内，尤其是海洋冰山的表面质量平衡，以及海洋山海的表面质量平衡。 为了调查这些中尺度旋风风暴系统的作用，各种卫星数据产品，最佳可用重新分析产品以及天气研究和预测（WRF）模型预测将用于开发旋风分离器频率和强度变化的场景，并在增强水文学周期中对这些影响以及这些对这些影响的影响以及这些对这些影响的影响可能对这些旋风量和大型群体表面质量破坏。
