The increase in pre-monsoon tropical cyclones in the Arabian Sea is related to black carbon emissions , according to a study released by the journal Nature . Experts from the University of Virginia (USA) believe that growing environmental pollution alters atmospheric circulation over the Arabian Sea by reducing the region's own vertical air current and creating conditions conducive to an increase in hurricanes.
Black carbon is a pollutant that gives soot its black color and is produced by the incomplete combustion of diesel, biofuels and biomass (burning of forests, etc.). Unlike carbon dioxide, which accumulates over decades in the atmosphere, black carbon disappears within weeks, but it has a strong impact on the environment. Previous research indicates that black carbon has a major impact on increasing global temperature.
