Why are gales frequent in Iceland during winter?

Gales are frequent in Iceland during winter primarily due to the influence of the Icelandic low, a persistent low-pressure center located between Iceland and southern Greenland.1

In winter, the North Atlantic Ocean remains significantly warmer than the surrounding continents, creating a temperature contrast that drives the formation of this low-pressure system. This system dominates wind circulation in the region and serves as a focal point for extratropical cyclones. These storms develop along fronts where cold polar air masses meet milder tropical air, and they intensify as they move northeastward toward Iceland. Because the growth rate of these storms depends on the intensity of the temperature contrast, winter storms are typically much stronger than those in summer, leading to the frequent gales experienced across the country.123
