Summary:
But its fate during the wet summer monsoon (May to September) had been unclear till now. Bengaluru: Like Janus, the Greek god, the Indian monsoon has two faces, according to a report by researchers from Germany in the journal “Science”. The researchers are able to show that ground-based sources of pollution can reach the stratosphere during the monsoon. “Our hypothesis is that the monsoon anticyclone is infused by South Asian convection that carries air pollution emissions upward from this region, with possible additional contributions from East Asia and Africa,” the authors say. However, some pollutants are lofted above the monsoon clouds, and chemically processed in a reactive reservoir before being redistributed globally..
