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.

Hara0940398我们目前对热带气旋（飓风）下的海气相互作用过程的认识还远远不能令人满意，这也是限制我们改进热带气旋预测（特别是强度预测）能力的因素之一。然而，进一步改进海气通量参数化和近地表湍流建模是一项艰巨的科学挑战，因为：（1）需要提高对所有相关过程的理解，包括近地表大气和海洋湍流、表面波、表面破碎波、海浪和气泡的产生、浪花和大气湍流之间的相互作用、气泡和海洋湍流之间的相互作用； (2) 这些过程发生在广泛的时间和空间尺度上，从风暴尺度到气泡和喷雾的微物理尺度； (3) 由于许多过程强烈依赖于表面波浪条件，因此可能有必要将大气、波浪和海洋模型完全耦合起来，以便正确预测海气相互作用过程及其对热带气旋动力学的影响。显然，我们需要协调一致的跨学科努力，以显着改进对热带气旋下海气相互作用过程的预测。因此，PI 团队正在组织一次研讨会，旨在： 确定需要重点关注的当前和长期科学问题；加强不同学科的科学家/工程师之间的交流；建立一个框架，促进和培育新颖的跨学科研究举措。该研讨会将由 3 个联合组织者组织，Tetsu Hara（海空相互作用）、Stephan Grilli（海洋工程、波浪破碎）和 Isaac Ginis（海洋和大气建模），并将于 2010 年在罗德岛大学奥尔顿·琼斯校区举行。PI 的目标是国际化、多学科的，但规模足够小，以便在一般性讨论中能够轻松沟通。我们将保持资历和多样性的平衡，并接触国际社会，特别关注早期职业调查员。该研讨会促进了国际合作，因为大约一半的参与者将来自其他国家。该奖项由 ENG 和 GEO 理事会共同资助。
