Hara0940398Our current understanding of air-sea interaction processes under tropical cyclones (hurricanes) is far from satisfactory and is one of the factors that are limiting our ability to improve tropical cyclone prediction (intensity prediction, in particular). Further improvement of air-sea flux parameterizations and near surface turbulence modeling, however, is a formidable scientific challenge because: (1) the need to improve understanding of all relevant processes, including near surface atmospheric and oceanic turbulence, surface waves, surface breaking waves, sea spray and bubble generations, interactions between sprays and atmospheric turbulence, interactions between bubbles and oceanic turbulence; (2) these processes occur over a wide range of temporal and spatial scales, from the storm scale to microphysical scales of bubbles and sprays; and (3) since many of these processes are strongly dependent on the surface wave conditions, it may be necessary to fully couple the atmospheric, wave, and ocean models in order to properly predict the air-sea interaction processes and their impact on tropical cyclone dynamics. It is evident that we need a coordinated interdisciplinary effort to significantly improve predictions of air-sea interaction processes under tropical cyclones. The PI team are thus organizing a workshop aimed on: identifying immediate and long term scientific issues to be focused upon; enhancing communication among scientists/engineers in different disciplines; and building a framework in which novel interdisciplinary research initiatives are promoted and nurtured. The workshop will be organized by 3 co-organizers, Tetsu Hara (air-sea interaction), Stephan Grilli (ocean engineering, wave breaking), and Isaac Ginis (ocean and atmospheric modeling), and will be held at the Alton Jones campus of the University of Rhode Island in 2010. The PIs will target an international and multi-disciplinary, but small enough group to allow for easy communication during general discussions. We will maintain a balance of seniority and diversity and reach out to the international community, paying special attention to early career investigators. The workshop promotes international cooperation since about half of the participants will be invited from other countries.This award is being co-funded by the ENG and GEO directorates.

HAA0940398在热带气旋（飓风）下对空气相互作用过程的当前理解远非令人满意，这是限制我们改善热带气旋预测（尤其是强度预测）的能力的因素之一。然而，进一步改善空气通量参数化和近表面湍流建模是一个巨大的科学挑战，因为：（1）需要提高对所有相关过程的理解，包括近地面大气和海洋湍流，表面波，表面波浪，表面断裂，海洋喷雾，海洋喷雾和气泡，在喷雾和大气湍流之间的相互作用，气泡湍流与海洋湍流之间的相互作用，相互作用； （2）这些过程发生在各种时间和空间尺度上，从风暴尺度到气泡和喷雾的微物理尺度； （3）由于这些过程中的许多过程都非常依赖于表面波条件，因此可能有必要充分搭配大气，波浪和海洋模型，以便正确预测空气海上的相互作用过程及其对热带旋风动力学的影响。显然，我们需要协调的跨学科努力，以显着改善热带气旋下空气交互过程的预测。因此，PI团队正在组织一个针对的研讨会：确定要关注的直接和长期科学问题；加强不同学科的科学家/工程师之间的沟通；并建立一个框架，在该框架中，促进和培育了新颖的跨学科研究计划。该研讨会将由3个共同组织者，Tetsu Hara（空气互动），Stephan Grilli（海洋工程，波浪破坏）和Isaac Ginis（海洋和大气建模）组织，并将在2010年的罗德大学（University of Rohode Island）举行。我们将保持资历和多样性的平衡，并与国际社会接触，并特别注意早期职业调查人员。研讨会促进国际合作，因为大约一半的参与者将受到其他国家 /地区的邀请。该奖项由Eng和Geo Direction共同资助。
