The response of the Aegean Sea to seasonal forcing by the Etesian winds is investigated, based on Copernicus products for weather forecasting (winds) and satellite information (sea-surface temperature (SST) and chlorophyll-α (chl-a) concentration), as well as fisheries records from the Hellenic Statistical Authority. To that end, a site-specific response criterion for upwelling intensity has hereby been developed, based on the zonal SST gradient between eastern and western Aegean. Combined use of the above criterion with lagged cross-correlation between wind, zonal surface temperature gradient, surface chl-a concentration and local fish landings reveals a well-hidden (until now) signal of chl-a increase in response to intensification of wind forcing, as well as a relation between fish landings and upwelling events, challenging the conclusions of previous studies suggesting that the Aegean Sea is immune to summer coastal upwelling, due to the great depth of its nutricline.

基于用于天气预报（风）和卫星信息（海面温度 (SST) 和叶绿素-α）的哥白尼产品，研究了爱琴海对埃特西亚风季节性强迫的响应(chl-a) 浓度），以及来自希腊统计局的渔业记录。为此，基于爱琴海东部和西部之间的纬向 SST 梯度，特此制定了针对上升流强度的特定地点响应标准。将上述标准与风、纬向表面温度梯度、地表 chl-a 浓度和当地鱼类上岸之间的滞后互相关结合使用，揭示了 chl-a 增加的隐藏（直到现在）信号响应风力增强，以及鱼类上岸和上升流事件之间的关系，挑战了先前研究的结论，即爱琴海由于其营养线的深度很大而不受夏季沿海上升流的影响。
