Analysis the physical principle of Fog and haze formation

The fog and haze formation is the result of natural, science and technology, human activity. the reason of The fog and haze are : combustion, vehicle exhaust, dust, but the the second outbreak of PM2.5 reasons are complex, including some chemical reaction. In fact, the reason is: 1, The accumulation of the fog and haze, namely the results of combustion, automobile exhaust, dust effects. 2, The fog and haze particles upward momentum -- hot air upward movement, wireless communication, the electromagnetic wave net sports. 3, no sustained wind. Three conditions have erupted persistent cause the fog and haze weather, indispensable, the second outbreaks of Pm2.5 are above these three conditions together of the results.
