Question
The graph to the right shows the daily average value of the Air Quality Index (AQI) for ozone in Phoenix, Arizona. Describe the two primary meteorological reasons why ozone levels are higher during the four calendar months (May June-July-August) than the four months (Nov Dec-Jan-Feb).jbeing certain to explain how each 6o factor contributes to the buildup. You cain neglect seasonal differences in the input of AQI Ozone 1991-2016 Mean 90 50 y polutants that are timate cause of llutants that are the ultimate cause of photochemical smog. Air Quality Index (AQI) for ozone at Phoenix, Arizona. Data are from the What is the meteorological reason for the dip in AQI in July? Environmental Protection AgencyExplanation / Answer
Earth ground level ozone is formed by the various resources some of the above are given below-
1- Fossil fuel combustion
2- Road transport
3- Refineries
4- Solvents
5- vegetations
6- forest fires
7- livestock products
8- Air conditioner and Refrigerator coolents
But all these sources produces the waste and the by products which then at the presence of the sunlight and heat in the form of catalyst initiates the reaction into the formation of the ozone and thus this increases the concentration of the ozone in the environment of ARizona
In may, june , july , august the concentration of ozone is highest because-
1- Availability of plenty of catalists such as sunlight and heat
2- Tremendous use of Ac's and the refregerator coolents at the time of repair and the leakages which releases the chloroflorocarbons, this converts the oxygen into the ozone.
In the month of july the rainy season started which causes somewhat decreement in the sunlight due to cloud and decreement in the heat due to raining which causes dip in the ozone concentration in july in Arizona
