The Icelandic low is a weather phenomenon that occurs when a low-pressure system forms near Iceland, bringing cold and stormy weather to the region. There are several synonyms for this term, including polar low, Arctic low, and Greenland low. While they all refer to the same type of weather system, each name reflects its specific location or characteristics. For instance, the term polar low suggests that the system is located near the North Pole, while the name Greenland low indicates that it is centered over Greenland. Despite the different names, these weather systems have one thing in common: They all bring chilly and unsettled conditions to the northern hemisphere.
