Swells that reach the coast of the Canary Islands from northern latitudes are well studied and documented, but scientific literature on the arrival of swells from the southern hemisphere is very scarce. The effects of this type of wave can be appreciated in the south coast of the Canary Islands at certain times of the year. These waves have low significant height, but long periods. The Spanish public system for forecasting of the marine environment (SIMAR database) may not be replicating this type of swell accurately. For this reason, its effect may have been underestimated in the design and management of coastal infrastructures. The aim of this research is to study the frequency and features of swells arriving from the extratropical region of the southern hemisphere to the Canary Islands, an archipelago located in the subtropical North Atlantic. For this purpose, a systematic visual observation of the waves reaching the coast of the Canary Island of Tenerife from the south, and comparisons with wave models and registers of buoys were carried out. The observation period was 1 year. A total number of six events with sufficient correlation were recorded. The possible origin of each of these events has been studied.

在加那利群岛南部海岸观测跨半球波

从北纬到达加那利群岛海岸的涌浪得到了很好的研究和记录，但关于南半球涌浪到达的科学文献却非常少。在一年中的某些时候，可以在加那利群岛的南海岸欣赏这种类型的海浪的影响。这些波浪的显着高度较低，但周期较长。西班牙海洋环境预测公共系统（SIMAR 数据库）可能无法准确复制这种类型的涌浪。因此，它在沿海基础设施的设计和管理中的影响可能被低估了。这项研究的目的是研究从南半球温带地区到达位于北大西洋亚热带的加那利群岛的涌浪的频率和特征。为此，对从南部到达特内里费岛加那利岛海岸的波浪进行了系统的目视观察，并与波浪模型和浮标记录进行了比较。观察期为1年。总共记录了六个具有足够相关性的事件。已经研究了这些事件中每一个的可能起源。
