Arctic haze is the phenomenon of a visible reddish-brown springtime haze in the atmosphere at high latitudes in the Arctic due to anthropogenic [1] air pollution.A major distinguishing factor of Arctic haze is the ability of its chemical ingredients to persist in the atmosphere for significantly longer than other pollutants.
Increasing interest in studies of phenomena such as Arctic haze led to a conference in 1977 in Lillestrøm, Norway with participation from scientists of seven different countries. Following this conference, the Arctic Air-Sampling Network (AASN) was created to share data between scientific organizations in each member nation. [6]
However, haze particles may act as condensation nuclei that leads to the subsequent vapor condensation and formation of mist droplets; such forms of haze are known as "wet haze". In meteorological literature, the word haze is generally used to denote visibility-reducing aerosols of the wet type suspended in the atmosphere .
An Arctic airmass is bringing the coldest air since last winter to the Plains and Midwest and into the South and East Coast, according to the National Weather Service. It's forecast to stretch ...
The area close to the surface of the water gets enveloped in an eerie mist or haze that resembles smoke, hence the nickname. ... It’s often seen on the Great Lakes when the first Arctic blast of ...
An Arctic blast gripped the northern Plains, Midwest and Great Lakes on Saturday, with millions of Americans under freeze warnings. More than 17 million people were cautioned Saturday under ...
Mitchell's investigation of Arctic haze in the 1950s found aerosol particles which apparently originated from industrial areas of Europe and China. [1] Using studies of nuclear fallout from bomb tests which showed how aerosols moved in the upper atmosphere, he compared global temperature statistics with the record of volcanic eruptions in a 1961 paper which put forward his view that large ...
The word Arctic comes from the Greek word ἀρκτικός (arktikos), "near the Bear, northern" [4] and from the word ἄρκτος (arktos), meaning bear. [5] The name refers either to the constellation known as Ursa Major, the "Great Bear", which is prominent in the northern portion of the celestial sphere, or to the constellation Ursa Minor, the "Little Bear", which contains the celestial ...
