Collaborative Research: Synoptic and Mesoscale Storms in the Southern Ocean and their Impact on Cryosphere

对南部高纬度大气-海洋相互作用的许多方面仍然知之甚少。例如，在气候变化和海洋变暖的情况下，大气旋和中尺度风暴系统与大气水分平衡的相互作用与北极的相应情况有奇怪的不同。该项目力求更好地量化水蒸气输送，特别是天气可变性的中尺度驱动因素对南极冰盖表面物质平衡的贡献，以及对南大洋海冰的年度演变的贡献。为了调查这些中尺度气旋风暴系统的作用，将利用各种卫星数据产品、现有的最佳再分析产品和天气研究和预报(WRF)模型预测，制定在加强的水文循环中气旋频率和强度发生变化的情景，以及这些情景可能对南极海冰和大陆表面物质平衡产生的影响。

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.
