swell A regular movement of marine waves created by wind stress in the open ocean which travels considerable distances away from the generating field and into another wind field. The waves are characterized by relatively smooth, generally unbroken, crests and a fairly regular wavelength, but swell increases in wavelength and decreases in wave height as it moves away from the generating area. Local wind waves may be superimposed upon swell waves as they approach a coastline, thereby creating sharper crests and a choppy sea (由空旷的海洋上的风压造成的海洋波浪的规则运动，它远离发电场移动，并移到另一个风场。浪的特点是相对平稳，一般不间断，有波峰和比较规则的波长，但当它远离电场时波长增加和波高减小都比较剧烈。当地风浪因为在海岸线相遇，会在涌浪叠加，从而创造一个更清晰的波峰和波涛汹涌的海浪。) |
