This Post-doctoral Research Fellowship (PRF) involves field measurements of atmospheric wind conditions near the surface of the ocean, during high sea conditions from a research platform in the North Sea. These measurements will be taken using a combination of wind measuring instruments (anemometers) and high speed camera system. The goal of this research is to improve our understanding of the interaction between the atmosphere and the ocean at the interface of wind driven waves. This PRF will provide an early career scientist an outstanding opportunity to interact with international collaborators in a challenging research environment working at the forefront of science in this area.This study seeks to deploy a suite of sensors onboard the FINO3 research platform in the North Sea, 80km offshore from Germany, to take direct measurements of momentum flux in high winds and high seas. The specific research objectives include:- obtain direct field measurements of the total air-sea momentum flux in high wind conditions; which combined with surrounding observations of the atmospheric boundary layer, sea state and local wave field, provide better parameterization of of air-sea momentum flux near the atmosphere-ocean interface.- measure the partitioning of the total wind stress between wave, turbulent, and viscous contributions.- assess the drag associated with each spectral component of the complex wave field with multiple wind and sea swell components and in the presence of whitecaps and sea spray, in order to improve coupled atmosphere-ocean models.The project with complement a wind-wave interaction study already in progress on the FINO3 research platform.

该博士后研究奖学金（PRF）涉及在北海研究平台的高海况期间，对海洋表面附近的大气风况进行实地测量。 这些测量将使用风测量仪器（风速计）和高速摄像系统进行。 这项研究的目的是提高我们对大气和海洋在风驱动波界面处相互作用的理解。 该PRF将为早期职业科学家提供一个绝佳的机会，在具有挑战性的研究环境中与国际合作者进行互动，在该领域的科学前沿工作。本研究旨在在距离德国80公里的北海FINO 3研究平台上部署一套传感器，以直接测量强风和公海中的动量通量。 具体的研究目标包括：-获得大风条件下海气动量通量的直接现场测量;结合周围大气边界层，海况和局部波场的观测，提供更好的海气界面附近海气动量通量的参数化。测量总风应力在波浪、湍流和粘性贡献之间的分配。评估与复杂波场的每个谱分量相关的阻力，该波场具有多个风和海浪分量，并且存在白浪和海浪，以改进耦合的大气-海洋模型。该项目补充了已经在FINO 3研究平台上进行的风浪相互作用研究。
