Question

How it forms dense fog at the coast of Newfoundland?

Answer 1

Dense fog forms at the coast of Newfoundland primarily due to the convergence of the cold Labrador Current from the Arctic and the warm Gulf Stream Current. When the warm, moist air brought by the Gulf Stream meets the cold surface of the Labrador Current, the air temperature drops to the dew point, causing condensation of water vapor into tiny droplets that form dense fog. This interaction creates heavy fog, which is particularly common and thick in this region and contributes to visibility hazards but also supports abundant marine life due to nutrient-rich waters.
