The effect was most pronounced（显著的） during the winter. The study is published in the Proceedings of the National Academy of Sciences (PNAS). Lead author Yuan Wang, from the Jet Propulsion Laboratory at the California Institute of Technology, said: "The effects are quite dramatic. The pollution results in thicker and taller clouds and heavier precipitation." Toxic atmosphere Parts of Asia have some of the highest levels of air pollution in the world. In China's capital, Beijing, pollutants frequently reach hazardous levels, while emissions in the Indian capital, Delhi, also regularly soar above those recommended by the World Health Organization. |
