Deadly Floods in China is the Result of Air Pollution

by Jonas BorchgrevinkJuly 14, 2015

According to a new study, air pollution and soot is the cause of China’s worst flood in more than 50 years. A region in the Sichuan province received 94 cm of rain in just five days, resulting in 200 dead and 300 000 IDPs. 

The researchers simulated the atmosphere above the heavily industrialized Sichuan region with different levels of emissions. If the air pollution, including smoke, multiple greenhouse gases, and aerosols, was not so severe, rainfall of the storm would have been 60% less.

    “We were amazed at the scale of the effect the pollution had,” Fan told Science.

Effectively it redistributed the precipitation from the wide area of the basin into the mountains.

There are more than 100 million people that live in the Sichuan region whom most are depending on heavy industries like iron and steel productions. To make matters worse, the region is surrounded by mountains that trap the pollution and build up moist.

Is there a connection between air pollution and weather? Other researchers think so; air pollution may be causing monsoons to hit South and East Asia earlier and harder. Some researchers have linked aerosols in the atmosphere to the intensity of cyclones and tornadoes.
