Researchers studied the weather and air-sea interactions in the northern Baltic Sea in the 1990s. They used data from weather stations on lighthouses and a research ship. The air temperature and wind speed were higher in the 1990s compared to the previous 30 years. The heat exchanged between the sea and air varied throughout the months, with heat going from the sea to the air most of the time. The weather near the coast affected the temperature, humidity, and heat exchange with the sea. Wind speed decreased closer to the coast due to certain weather patterns. Overall, the study showed how the weather and ocean interact in this region during the 1990s.
