  • Researchers from China and the U.S. have developed a novel computer model that can help accurately “predict” air pollution levels in the region, a season in advance.
  • The statistical model uses certain climatic patterns related to the oceans.
  • Oceans have a regulatory effect on the wintertime air pollution over northern India.
  • The study found that levels of wintertime aerosol pollution over northern India is regulated mainly by a combination of
    • El Nino - a climate cycle in the Pacific Ocean with a global impact on weather patterns
    • Antarctic Oscillation (AAO) - a low frequency mode of atmospheric variability of the southern hemisphere.
  • The new model could allow the government to forecast aerosol pollution conditions in winter and accordingly improve plans for pollution control.
