Aerosols in atmosphere tend to weaken hurricanes and cyclones
A new study has shown that aerosols in the atmosphere produced from human activities tend to weaken hurricane or tropical cyclones.
According to the study by a team of Texas A&M University researchers, aerosols tend to weaken the development of hurricanes or typhoons and also cause hurricanes to fall apart earlier, and wind speeds are lower than storms where anthropogenic aerosols are not present.
Renyi Zhang, University Distinguished Professor in Atmospheric Sciences said that the results are surprising because other studies have leaned global warming by greenhouse gases makes hurricanes more intense and frequent, but aerosols may operate oppositely than greenhouse gases in terms of influencing hurricanes.
The researchers examined how anthropogenic aerosols produced from human activities, such as from factories, power plants, car and airplane emissions and other forms, play a role in the development of hurricanes, and their findings could be crucial in how we evaluate and prepare for destructive tropical storms.
The study was published in the current issue of Nature Climate Change.
