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

在南方高纬度地区，人们对大气-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情况有着奇怪的不同。该项目旨在更好地量化水汽输送，特别是天气变率的中尺度驱动因素，对南极冰盖表面质量平衡的贡献，以及对南大洋海冰年度进展的贡献。为了研究这些中尺度气旋风暴系统的作用，将使用各种卫星数据产品、现有的最佳再分析产品和天气研究与预报（WRF）模式预测来开发在不断加剧的水文循环中气旋频率和强度变化的情景，以及这些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.
