WebJul 16, 2008 · Stratospheric ozone is constantly produced by the action of the sun's ultraviolet radiation on oxygen molecules (known as photochemical reactions). Although ozone is created primarily at tropical latitudes, large-scale air circulation patterns in the lower stratosphere move ozone toward the poles, where its concentration builds up. WebOzone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NO X ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can …
