Based on the observation, the winter air pollution problems in China might be getting worse due to the changes in the circulation of atmosphere that affects the Arctic sea ice and Eurasian snow that caused by global climate change. The findings and data analysis suggest that the sea ice and snowfall change China's winter monsoon.

According to EurekaAlert, the large-scale perturbations caused by the global climate can change the significant regional impacts. It helps to create stagnant atmospheric conditions and creates winter air pollution into the country's most populated and industrial centers. The researchers have studied the short-term weather conditions, yet the fundamental climate effects are still not well understood.

Yufei Zou and his colleagues had studied the ventilation conditions for over 35 years in the region, which is made up of interconnected to horseshoe-shaped basins where the air pollutant will rely on the ventilation on large-scale weather systems. For the last four years, the emissions in China have been decreasing but the serious winter air pollution is not even getting better.

Phys Org added that on March 15 it was reported in the journal Science Advances that presents a paper that shows a clear example and believed that it is the first to link the sea ice and snowfall levels to regional winter air pollution. In 2013, the East China Plains, which include the capital Beijing was first gained a global attention during its winter when the U.S. embassy instrument recorded the massive high levels of PM 2.5 particles.

However, the long-term air quality measurement is not available China, so the researchers will do the estimates based on the visibility and satellite data measurements. To be able to analyze the historical records, Yufei Zou and colleagues created a new Pollution Potential Index (PPI)that will use an air temperature and surface winds to measure the winter air pollution.

Researchers said that despite the efforts in reducing the emissions, the winter air pollution will perhaps continue for the future and it is partly climate-driven now, and emissions are no longer the driver of conditions. The impact of the global climate in China is may be unique because of its geography and sensitivity when it comes to changes in the atmospheric circulation structure.
