Ozone (O3) is a naturally occurring gas found in the stratosphere – in the range of 15 to 35 kilometres above earth’s surface, called the ozone layer or the ozone shield. The ozone layer absorbs around 98 per cent of medium frequency ultraviolet rays coming from the sun, which otherwise can potentially damage life forms on the earth’s surface. Ozone depletion, or thinning of the ozone layer due to conversion of O3 to O2 (oxygen), is a major threat to environment because it increases the harmful UV rays coming to earth’s surface, thereby increasing chances of skin cancer, eye cataracts, and even genetic damage.Continue reading
While common causes of pollution in north India are the smoke from power generators and power plants, vehicles, burning of crop stubble in the region of Punjab and Haryana, etc., the geographic particulars make the north-Indian cities like Delhi more susceptible to air pollution that the rest of the country, to the extent of making it severy unhealthy to breathe and visibility limited to as low as 400 metres on some days in the winter season.
Anti-cyclonic Weather Conditions
The atmospheric circulation over north India happens to be such that the areas surrounding the national capital Delhi come in a zone of Anti-cyclonic weather conditions during winter. This condition keeps the air movement calm, and aggravate building up of pollutant concentration in lower troposphere, as calm surface winds are not able to disperse pollutants over a larger region.Continue reading
