摘要通过SEASAT雷达高度计测量，首次获得了海洋涌浪产生、传播和消散的天气学观测资料。连续的有效波高和表面风速测量值是从高度计观测中推导出来的;通过假设皮尔森和莫斯科维茨充分发展的波浪模型适用，一个确定最小涌浪的模型被用来生成1978年6月至10月（SEASAT寿命）期间太平洋的三天平均涌浪图。在南太平洋的高纬度地区（南纬40°以南），用高度计观测到大量涌浪事件的产生，这是一个连续的涌浪源。分析了不同涌浪事件向北传播和消散方式的区域差异。在向北传播的罗斯海附近产生的涌浪家庭可以冲击北美海岸的能量显着超过海洋。
Abstract The first synoptic observations of ocean swell generation, propagation, and dissipation have been obtained from SEASAT radar altimeter measurements. The sequential significant wave height and surface wind speed measurements have been deduced from altimeter observations; by assuming that the Pierson and Moskowitz fully developed wave model applies, a model for determining minimum swell is used to generate three‐day average swell maps of the Pacific Ocean for the period June to October 1978, the SEASAT lifetime. The generation of numerous swell events was observed with the altimeter in the high‐latitude regions of the South Pacific Ocean (south of 40°S latitude), which was acting as a continuous swell source. Regional differences in the northward propagation and dissipation patterns of different swell events have been analyzed. In their northward propagation the swell families generated in the Ross Sea neighborhood can impinge the coasts of North America with significantly more energy than the swel...
