Abstract

Based on satellite data on sea surface temperature (1985–2018) and surface wind (1992–2017), the parameters of low-frequency variability are calculated and analyzed for the intensity of the Canary, Benguela, Californian, Peruvian, and Chilean upwellings. It is shown that all the analyzed large-scale wind-driven upwellings have intensified in the recent 30 years. The main contribution to this intensification is made by the strengthening of offshore wind. An exception is the Peruvian upwelling, where a trend caused by the wind stress curl intensification prevails.

摘要

根据有关海表温度（1985–2018）和地表风（1992–2017）的卫星数据，计算并分析了金丝雀，本格拉，加利福尼亚，秘鲁和智利上升流强度的低频变化参数。结果表明，在最近30年中，所有已分析的大型风动力上升都在加剧。海上风电的加强是对这种加剧的主要贡献。秘鲁的上升流是一个例外，其中风应力卷曲增强引起的趋势盛行。
