70% of the Earth's surface is the air-sea interface. A huge amount of energy and gas is exchanged between the atmosphere and ocean; exchanges that are crucial for life on earth. Climate models, weather and wave forecasts depend on oversimplified models for these exchanges. Oversimplification limits accuracy, with outcomes ranging from inaccurate climate predictions to costly and unnecessary rerouting of ships or evacuations of oil platforms. This project promises new knowledge of the turbulent air flow above waves through innovative, ambitious experiments in our laboratory wind-wave tanks. Concurrently, novel numerical simulations will enable new models for sea drag coefficient, the most critical component in air-sea interaction models.

地球表面的70％是空气接口。大气和海洋之间交换了大量的能源和气体。对地球上生活至关重要的交流。气候模型，天气和波浪预测取决于这些交换的过度简单模型。过度简化的限制了准确性，其结果范围从不准确的气候预测到船舶的昂贵和不必要的重新穿线或撤离石油平台。该项目有望通过在我们的实验室风波储罐中进行创新的，雄心勃勃的实验，了解波浪上方的湍流流动的新知识。同时，新型的数值模拟将为海上拖动系数提供新的模型，这是气海相互作用模型中最关键的组件。
