摘要

SWOT任务的卫星图像分析提供了赤道太平洋中部和东部内部孤立波（ISWs）序列的前所未有的细节。2024年3月27日至9月10日共发现226个isw，其中44个与小尺度锐锋直接相关。ka波段雷达干涉仪（KaRIn）和光学图像之间的卫星协同作用表明，这些波在太平洋冷舌（PCT）内传播了很长的距离。选取的21个案例表明，波的平均传播时间至少为19小时，并可能持续超过48小时。这些ISW序列可能从PCT的一端沿其经向宽度传播到另一端。由于isw输送质量和动量，因此在南北赤道锋之间传递信息，我们简要讨论了可能的物理含义。

Longevity of internal solitary waves in the Pacific Cold Tongue: synergies with SWOT

Analysis of satellite images from the SWOT mission provide unprecedent details of trains of Internal Solitary-like Waves (ISWs) in the central and eastern equatorial Pacific Ocean. A total of 226 ISWs were found between March 27 and September 10 (2024), 44 of which are directly associated with small-scale sharp fronts. Satellite synergies between the Ka-band Radar Interferometer (KaRIn) and optical imagery reveal that these waves propagate for long distances within the Pacific Cold Tongue (PCT). A selection of 21 cases shows that waves propagate on average for at least 19 h and may endure up to more than 48 h. These ISW trains may travel from one edge of the PCT, across its meridional width, to the other edge. Since ISWs transport mass and momentum and therefore convey information between the north and south equatorial fronts, we briefly discuss possible physical implications.
