Haze is traditionally an atmospheric phenomenon where dust, smoke and other dry particles obscure the clarity of the sky. The World Meteorological Organization manual of codes includes a classification of horizontal obscuration into categories of fog, ice fog, steam fog, mist, haze, smoke, volcanic ash, dust, sand and snow.[1] Sources for haze particles include farming (ploughing in dry weather), traffic, industry, and wildfires.
Seen from afar (e.g. approaching airplane) and depending upon the direction of view with respect to the sun, haze may appear brownish or bluish, while mist tends to be bluish-grey. Whereas haze often is thought of as a phenomenon of dry air, mist formation is a phenomenon of humid air. However, haze particles may act as condensation nuclei for the subsequent formation of mist droplets; such forms of haze are known as "wet haze."
In the United States and elsewhere, the term "haze" in meteorological literature generally is used to denote visibility-reducing aerosols of the wet type. Such aerosols commonly arise from complex chemical reactions that occur as sulfur dioxide gases emitted during combustion are converted into small droplets of sulfuric acid. The reactions are enhanced in the presence of sunlight, high relative humidity, and stagnant air flow. A small component of wet haze aerosols appear to be derived from compounds released by trees, such as terpenes. For all these reasons, wet haze tends to be primarily a warm-season phenomenon. Large areas of haze covering many thousands of kilometers may be produced under favorable conditions each summer.

Air pollution [link]
Haze often occurs when dust and smoke particles accumulate in relatively dry air. When weather conditions block the dispersal of smoke and other pollutants they concentrate and form a usually low-hanging shroud that impairs visibility and may become a respiratory health threat. Industrial pollution can result in dense haze, which is known as smog.
Since 1991, haze has been a particularly acute problem in Southeast Asia, Indonesian forest fires burnt to clear land being the reason. In response the 1997 Southeast Asian haze, the ASEAN countries agreed on a Regional Haze Action Plan (1997) and later signed the Agreement on Transboundary Haze Pollution (2002) however the pollution is still a problem today. Under the agreement the ASEAN secretariat hosts a co-ordination and support unit.[2]
In the United States, the Interagency Monitoring of Protected Visual Environments (IMPROVE) program was developed as a collaborative effort between the US EPA and the National Park Service in order to establish the chemical composition of haze in National Parks and establish air pollution control measures in order to restore the visibility to pre-industrial levels.[3] Additionally, the Clean Air Act requires that any current visibility problems be remedied, and future visibility problems be prevented, in 156 Class I Federal areas located throughout the United States. A full list of these areas is available on EPA's website.[4]
Obscuration [link]
Haze causes issues in the area of terrestrial photography, where the penetration of large amounts of dense atmosphere may be necessary to image distant subjects. This results in the visual effect of a loss of contrast in the subject, due to the effect of light scattering through the haze particles. For these reasons, sunrise and sunset colors appear subdued on hazy days, and stars may be obscured at night. In some cases, attenuation by haze is so great that, toward sunset, the sun disappears altogether before reaching the horizon. (see example).[5] Haze can be defined as an aerial form of the Tyndall effect therefore unlike other atmospheric effects such as cloud and fog, haze is spectrally selective: shorter (blue) wavelengths are scattered more, and longer (red/infrared) wavelengths are scattered less. For this reason many super-telephoto lenses often incorporate yellow filters or coatings to enhance image contrast.
Infrared (IR) imaging may also be used to penetrate haze over long distances, with a combination of IR-pass optical filters (such as the Wratten 89B) and IR-sensitive detector.

Harikrish Menon

Career
He began his professional career at R.A.P. (Roslan Aziz Production) a Malaysian record label owned by acclaimed music producer Roslan Aziz. He has since worked with many of Malaysia's top performing artist such as Sheila Majid, Ning Baizura, Amir Yusoff, Zainal Abidin, Sarifah Aini and Malaysian rap sensation Too Phat just to name a few. Besides producing for local Malaysian performing artist, he has also produced albums for many performing artist around the region. Artist such as Kris Dayanti of Indonesia and Singaporean rap sensation Haikel. Which has allowed him to develop a musical scope that covers across almost all genres. In the Mid 1990's he also performed with the band Asia Beat.
He was the first Malaysian to appear on the BBC UK Dance Singles Charts, for Changes. His single Freak made the Top 10 of the National Top 100 Singles chart in the Netherlands.
Evil
Evil, in a general context, is the absence or opposite of that which is ascribed as being good. Often, evil is used to denote profound immorality. In certain religious contexts, evil has been described as a supernatural force. Definitions of evil vary, as does the analysis of its motives. However, elements that are commonly associated with evil involve unbalanced behavior involving expediency, selfishness, ignorance, or neglect.
In cultures with an Abrahamic religious influence, evil is usually perceived as the dualistic antagonistic opposite of good, in which good should prevail and evil should be defeated. In cultures with Buddhist spiritual influence, both good and evil are perceived as part of an antagonistic duality that itself must be overcome through achieving Śūnyatā meaning emptiness in the sense of recognition of good and evil being two opposing principles but not a reality, emptying the duality of them, and achieving a oneness.
The philosophical question of whether morality is absolute, relative, or illusory leads to questions about the nature of evil, with views falling into one of four opposed camps: moral absolutism, amoralism, moral relativism, and moral universalism.
Evil (Grinderman song)
"Evil" (often stylised as EVIL) is a song by alternative rock band Grinderman, written collectively by Nick Cave, Warren Ellis, Martyn P. Casey and Jim Sclavunos. The song was featured as the fifth track on the band's second and final studio album, Grinderman 2 (2010). On Record Store Day 2011, "Evil" was released as a limited edition single, on 12" vinyl with an enclosed CD, with various remixes.

Evil (Interpol song)
"Evil" is a song by American rock band Interpol. It was released as the second single from their second studio album, Antics, on January 3, 2005. The song is believed to be about Rosemary West, a serial killer who raped and murdered teenage girls with her husband Fred West. "Evil" peaked at number 18 on the UK Singles Chart and number 24 on Billboard magazine's Modern Rock Tracks chart. In Australia, the song was ranked number 76 on Triple J's Hottest 100 of 2004.
Music video
The video, directed by Charlie White, shows a life-size marionette or puppet who travels via ambulance to a hospital emergency room following a car accident at which he is initially examined by live actors as he sings the lyrics to the song. The puppet's name, Norman, was coined by fans on Interpol's message board shortly after the video premiered.

Evil Ways
by: SantanaYou got to change your evil ways, baby
Before I stop loving you
You got to change, baby
And every word that I say is true
You've got me runnin' an' hidin' all over town
You've got me sneakin' an' a'peepin' and runnin' you down
This can't go on, Lord knows you got to change, baby
Baby, when I come home, baby
My house is dark and my pots are cold
You hangin' 'round, baby
With Jean and Joan and a who knows who
I'm getting tired of waitin' and foolin' around
I'll find somebody, that won't make me feel like a clown
This can't go on, Lord knows you got to change
When I come home, baby
My house is dark and my pots are cold
You hangin' 'round, baby
With Jean and Joan and a who knows who
I'm gettin' tired of waitin' and foolin' around
I'll find somebody, that won't make me feel like a clown
This can't go on, yeah yeah yeah
