The atmosphere and oceans control the Earth's climate. The ocean surface boundary layer (OSBL) is the upper 300m or so of the oceans and it is the part of the ocean that is directly affected by the atmosphere. So the OSBL acts to couple the atmosphere and deeper oceans together: it mediates the transfer of heat, momentum and important greenhouse gases such as carbon dioxide, and controls the supply of nutrients to the plankton that grow in the ocean surface boundary layer. In addition the temperature of the sea surface has an impact on weather forecasts for timescales of days to seasons. The sea surface temperature is largely set by the OSBL. It is clear then that the ocean surface boundary layer it truly at the heart of weather and climate. But our knowledge of the OSBL is very incomplete, and this means our quantitative models are not accurate. Nevertheless, it is a very exciting time to be doing research into the OSBL because we have new ideas about the fundamental processes that control the its evolution from timescales of days to years, and we also have exciting new tools to measure the ocean surface boundary layer. OSMOSIS will bring together a team of meteorologists and oceanographers with backgrounds in theory, computer modelling and observations, with the aim of making a step change to our understanding and our predictive power of the OSBL. We shall do this with a combination of new theory and new measurements. We will develop theory into the fundamental physics of the OSBL using the powerful new computational tools, which allow us to simulation the three-dimensional, time varying motions of the water in the OSBL. By careful analysis of the results of these computations we shall develop simpler representations of the OSBL that can be used in weather and forecast models. Will plan two research cruises and a range of instruments attached to fixed moorings to measure the OSBL at a level of detail never previously attempted. The cruises will enable us to observe at close quarters how the OSBL evolves under different weather regimes. The moorings will be left to gather data over a whole year, which will show us the seasonal evolution of the OSBL. These data will provide stringent tests for our new theoretical ideas, and our simpler representations. Finally, we are doing this research in conjunction with the Met Office and the European Centre for Medium Range Weather forecasting. We shall work closely with them doing the project, and their involvement will ensure that our results make a difference to the practise of weather and climate forecasting.

大气和海洋控制着地球的气候。海洋表面边界层（OSBL）是海洋上层300m左右，是海洋中直接受大气影响的部分。因此，OSBL 的作用是将大气和更深的海洋耦合在一起：它调节热量、动量和二氧化碳等重要温室气体的传递，并控制对在海洋表面边界层生长的浮游生物的营养供应。此外，海面温度也会影响天到季节时间尺度的天气预报。海面温度主要由 OSBL 决定。很明显，海洋表面边界层确实是天气和气候的核心。但我们对 OSBL 的了解非常不完整，这意味着我们的定量模型并不准确。尽管如此，对 OSBL 进行研究仍然是一个非常令人兴奋的时刻，因为我们对控制其从数天到数年的时间尺度演化的基本过程有了新的想法，而且我们还有令人兴奋的新工具来测量海洋表面边界层。 OSMOSIS 将汇集具有理论、计算机建模和观测背景的气象学家和海洋学家团队，旨在逐步改变我们对 OSBL 的理解和预测能力。我们将结合新理论和新测量来做到这一点。我们将使用强大的新计算工具将理论发展为 OSBL 的基础物理，这使我们能够模拟 OSBL 中水的三维、随时间变化的运动。通过仔细分析这些计算结果，我们将开发可用于天气和预报模型的更简单的 OSBL 表示。将计划两次研究巡航和固定系泊装置上的一系列仪器，以以前从未尝试过的详细程度测量 OSBL。这些巡航将使我们能够近距离观察 OSBL 在不同天气情况下如何演变。系泊装置将用于收集一整年的数据，这将向我们展示 OSBL 的季节性演变。这些数据将为我们的新理论思想和更简单的表示提供严格的检验。最后，我们正在与英国气象局和欧洲中期天气预报中心合作进行这项研究。我们将与他们密切合作开展该项目，他们的参与将确保我们的成果对天气和气候预报的实践产生影响。
