Identify climate and topographical factors that intensify air pollution and help reduce air pollution.?

• Answer:

  Hello "Baby Girl"! Well, this is a great question, which needs, though, a pretty long answer; briefly, though: Air Pollution intensifies in the cases of humid atmosphere and low/ no wind! This is more frequent in cities surrounded by mountains, on the contrary ones close to the sea get frequent breeze and the polluted air disperse away! Also, natural air flow could assist the disperse of the polluted air, so, if the "high" region of the city is, somehow, warmer, there will be a steady flow of air from the "low" side, due to air density differences! ::::::
