Fog always attached to any place of mystery. The largest number of foggy days at sea level – an average of more than 120 a year – is observed on the Canadian island of Newfoundland in the Atlantic Ocean.
Let’s see how the city looks and the nature of it, for the fog.
Fog called atmospheric phenomenon, the accumulation of water in the air, formed by tiny particles of water vapor.

Relative humidity at mists typically close to 100% (at least greater than 85-90%). However, in extreme cold (-30 ° and below) in populated areas, railway stations and airfields so-called freezing fog can occur at any relative humidity (even less than 50%).

There is a stereotype that London is constantly shrouded in a dense fog. In fact, the fog was typical for London in the past, at a time when Britain was at the forefront of industrialization and its numerous factories covered the sky with smoke. Houses in London were heated with coal. Smoke from the pipes is mixed with fog, creating smog, which had popularly nicknamed “the London special.”
Currently, foggy days in London in about 45 years. Particularly frequent fogs in January and February. Recall that on the Canadian island of Newfoundland in the Atlantic Ocean foggy days a year, much more – 120.
