Asian brown cloud

The Asian brown cloud is a cyclical and annual phenomenon. It is an enormous cloud of pollution that stretches across an area from the Red Sea to China. It is 3 kilometres thick.

The Asian brown cloud is not always present. It forms outside the monsoon season (from December to April) when precipitation is low and atmospheric pollution is not washed away.

Impact of the Asian brown cloud

This cloud of pollution first appeared at the end of the 1990s. It has caused several climatic disturbances and it has recently been suggested that it could be responsible for the intensification of cyclones over the Arabian Sea. Its negative impact on health has also been demonstrated.

The Asian brown cloud is recognised as being the biggest pollution in the world.
