摘要：Air pollution is the most commonly observed weather phenomena on urban and coastalindustrial area. It has been play an important role on rainfall and climate variability in synoptic scalesystem. In the present study we have simulated the concentration of air pollutants and the rainfall data overthe coastal city of Visakhapatnam (17°.68’N, 83°.21’E) by using histograms for this study. The observingtime period is selected from (01-04-2012 to 01-03-2013). The air pollution data is collected from the areaof CMQY RAMKY in the coastal industrial city of Visakhapatnam with the parameters SO2, NO2, CO2,NH3, PM 10 and PM2.5. This study is could predict the concentration of air pollutants and monthlyvariation in rainfall. . In the month of April the carbon monoxide (CO) values are very high whencompared with the other pollutants, the highest value of CO is 600μg/m3 simultaneously the rainfall valuesare very low and the days of rainfall are low. While in the month of May, same pattern continues, theconcentration of CO levels are very high than other pollutants. In the month June due to the onset ofmonsoon the concentration of pollutants are very low, the CO levels are very low compared to all otherpollutants. The precipitation will wash out the heavy metals and trace gaseous particles.
