The upwelling in the Baltic Sea region is very common phenomenon. According to different studies, in some places it can exist almost one-third of the year leading to vertical mixing and transporting fresh, rich in nutrients water from deeper layers to the surface. The upwelling phenomenon has been analysed for years 2010–2016, during thermally stratified period, i.e. between May and September. Surface layer temperature from coupled ecosystem model of the Baltic Sea – 3D CEMBS was analysed together with NOAA/AVHRR satellite SST observations. Wind data from weather forecasting model – UM from ICM UW were also analysed to describe favourable conditions for the upwelling occurrences. The research includes statistical analysis of entire Baltic Sea region as well as particular examples from selected areas. Areas of upwelling occurrences were found along almost entire coastline of the Baltic Sea. Main areas were located along Swedish coast in Baltic Proper, Oland and along Finnish coast in the Gulf of Finland, where the event can last up to 30% of the time. Other areas, with frequencies over 20%, include Polish coast, Gotland and Bay of Bothnia. It was determined that collected results were in good agreement with earlier studies, with satellite data giving slightly higher frequencies closer to the shore. Based on these results, an automated coastal upwelling detection system was designed and launched in operational mode together with the 3D CEMBS model.

波罗的海地区的上升流是非常普遍的现象。根据不同的研究，在某些地方，它可能存在于一年的近三分之一时间内，导致垂直混合并将新鲜，营养丰富的水从深层输送到地面。在热分层期间（即5月至9月），对2010-2016年的上升现象进行了分析。分析了来自波罗的海– 3D CEMBS耦合生态系统模型的表层温度，以及NOAA / AVHRR卫星SST观测值。还分析了来自天气预报模型– ICM UW的UM的风数据，以描述上升事件的有利条件。该研究包括对整个波罗的海地区的统计分析，以及选定地区的具体实例。在波罗的海几乎整个海岸线上都发现了上升流的区域。主要区域位于厄兰岛波罗的海沿岸的瑞典沿岸以及芬兰湾的芬兰沿岸，该事件最多可持续30％的时间。频率超过20％的其他地区包括波兰海岸，哥得兰岛和博特尼亚湾。可以确定的是，收集的结果与早期的研究非常吻合，卫星数据给出了离​​岸边稍高的频率。基于这些结果，设计了一个自动化的沿海上升流检测系统，并与3D CEMBS模型一起以运行模式启动。该事件最多可以持续30％的时间。频率超过20％的其他地区包括波兰海岸，哥得兰岛和博特尼亚湾。可以确定的是，收集的结果与早期的研究非常吻合，卫星数据给出了离​​岸边稍高的频率。基于这些结果，设计了一个自动化的沿海上升流检测系统，并与3D CEMBS模型一起以运行模式启动。该事件最多可以持续30％的时间。频率超过20％的其他地区包括波兰海岸，哥得兰岛和博特尼亚湾。可以确定的是，收集的结果与早期的研究非常吻合，卫星数据给出了离​​岸边稍高的频率。基于这些结果，设计了一个自动化的沿海上升流检测系统，并与3D CEMBS模型一起以运行模式启动。
