根据1999年8月至2004年7月QuikSCAT卫星对海面10 m以上风速和风向的连续5年观测资料，提出了一个全球海洋风的交互式气候学模型（COGOW）。这一气候学提供了第一个高空间分辨率、基于观测的在线海洋风图集。用户可以从COGOW网络地图集中检索表格和图形形式的气候风图和风统计数据。这些数据覆盖全球，提供了关于船舶和浮标采样稀少的世界海洋区域风的统计数据的高度准确的信息。本文以夏威夷夏威夷大岛爱媛丸号沉船的打捞为例，说明COGOW的使用和价值。海气相互作用的证据，COGOW内可见的许多风现象之一，进行了讨论，以进一步熟悉COGOW用户。最后，COGOW的效用方面的各种业务和研究社区进行了总结。
An interactive Climatology of Global Ocean Winds (COGOW) is presented based on 5 years (August 1999–July 2004) of QuikSCAT satellite measurements of wind speed and direction 10 m above the sea surface. This climatology provides the first high spatial resolution, observationally based, online atlas of ocean winds. Users can retrieve climatological wind maps and wind statistics, both in tabular and graphical form, from the COGOW web-based atlas. The global coverage of these data provides highly accurate information about the wind statistics in regions of the world ocean that are sparsely sampled by ships and buoys. A case study of the recovery of the vessel Ehime Maru off the Hawaiian Island of Oahu is presented to demonstrate the usage and value of COGOW. Evidence of air–sea interactions, one of many wind phenomena visible within COGOW, is discussed to further familiarize users with COGOW. Finally, the utility of COGOW with regard to various operational and research communities is summarized.
