(2) Meteorological conditions mean that the weather situation causes a certain place to heat up and cool down within a certain period of time to form an inverse temperature, and there is no wind at the lower level or the wind speed is very small, so that pollutants cannot be effectively diffused, but all of them are concentrated near the ground.

(3) The secondary reaction is based on the above two points. When pollutants stay in a place for a long time, mutual reactions and photochemical reactions will occur, resulting in new pollutants.
