Air pollution in China and other Asian countries is having far-reaching impacts on weather patterns across the Northern Hemisphere, a study suggests.

Researchers have found that pollutants are strengthening storms above the Pacific Ocean, which feeds into weather systems in other parts of the world.

The effect was most pronounced during the winter.

The study is published in the Proceedings of the National Academy of Sciences (PNAS).
