Why are fog and rain common in the southern Bering Sea?

The southern Bering Sea experiences frequent fog and rain primarily due to its specific climate patterns and the influence of maritime air masses. While the region is situated at a latitude similar to Great Britain, its climate is significantly more severe, characterized by cool, rainy summers.1

The prevalence of these conditions is linked to the presence of low-pressure systems, such as the Aleutian low, which is a large cyclonic center that influences the region's weather. These systems, along with the general movement of maritime air, contribute to the high annual precipitation in the southern part of the sea, which exceeds 40 inches (1,000 millimeters), occurring mainly as rainfall. Additionally, the interaction between the sea's surface temperatures and the overlying atmosphere creates the conditions necessary for frequent fog, which is a common navigational challenge in the area.213
