Processes of the exchange of energy and momentum at the sea-ice/ocean/atmosphere interface are key processes for the polar climate system. Heat and moisture fluxes are strongly modulated by open water fractions associated with polynyas, having important consequences for the atmosphere, ocean processes, ice formation, brine release, gas exchange and biology. The project aims at the study of the atmospheric processes forcing and maintaining polynyas in the Greenland area. The study will focus on the interaction between the katabatic wind system and the sea-ice/ocean system in the coastal area of north and northwest Greenland, and on the atmosphere/sea-ice/ocean exchange processes over the North Water Polynya (NOW). The main tool of the experimental study will be the polar aircraft of the Alfred-Wegener Institute (AWI). The experiment will be carried out in coordination with AWI and with the Canadian ArcticNet program, and is part of the International Polar Year (IPY). The data of the experiment will be used for the validation of model simulations and parameterisations.

海冰/海洋/大气界面的能量和动量交换过程是极地气候系统的关键过程。热量和水分通量强烈调制开放水域分数与polynyas，有重要的后果，大气，海洋过程，冰的形成，盐水释放，气体交换和生物。该项目的目的是研究格陵兰地区冰穴形成和维持的大气过程。这项研究将侧重于格陵兰北部和西北部沿海地区的下吹风系统与海冰/海洋系统之间的相互作用，以及北水Polynya（NOW）上空的大气/海冰/海洋交换过程。实验研究的主要工具将是阿尔弗雷德-韦格纳研究所（AWI）的极地飞机。该实验将与AWI和加拿大ArcticNet计划协调进行，是国际极地年的一部分。实验数据将用于验证模型模拟和参数化。
