tåker

Tåker is a term primarily used in Scandinavia, particularly in Norway and Sweden, referring to fog or mist. It describes a weather phenomenon where visible water droplets or ice crystals suspended in the air at or near the Earth's surface reduce horizontal visibility. The term encompasses various intensities of atmospheric moisture, from light mist to dense fog. Tåker can form under several conditions, including when moist air cools to its dew point, when warm, moist air moves over a cooler surface, or when precipitation falls through a layer of cold air. The presence of tåker can significantly impact transportation, causing delays and hazardous conditions for road, air, and sea travel. The duration and density of tåker are influenced by factors such as temperature, humidity, wind speed, and geographical features. Coastal areas and valleys are often prone to experiencing tåker more frequently than open plains.
