Heavy haze frequently collects in this region in the autumn, thanks to a fewfactors. Agricultural fires and increased fuel burning for warmth increase theamount of pollutants. In addition, cool air from the Himalaya sinks over thesouth side of the mountain range, trapping aerosols—tinyliquid or solid particles suspended in air. And behavior of the Asianmonsoon produces few strong winds that would push the haze out of the area.
