MIT researchers have discovered the reason why aerosols storms caused more intense storms in recent research.
The research showed, based on their observations of the Earth’s atmosphere, that there are stronger hurricanes where high concentrations of aerosolas present in a specific area, such as tropical regions.
So far, it is known that there was some connection to aerosol and storm surges, however, the reason behind science was not clear. The researchers used a new method called the “moisture-entrainment”, where aerosol increases humidity in the air around clouds.

“Cleaning up pollution could reduce the number of storms,” said Tim Cronin, associate professor of atmospheric science at MIT. “Overall, this provides a way for people to have a footprint on the climate that we may not have understood much in the past,” he continued. .
Aerosols, defined as any grains that are too small to be seen with the naked eye in the air, are generated by both human activity and natural onions that can have long-term effects on the environment. Biofuel combustion, fusion in several vehicles and factories; Volcanic eruptions emitting ash, sea spray, and dust storms are examples of these processes.
In normal cases, the particles with a surface can help the formation of clouds, serve as a basis for a water valve to condense and form it.individual drops and come together afterwards. The integrated droplets, which are large droplets in size, can turn to water. However, when these tiny particles are thick, the droplets they form do not come together easily, causing storm surges.
The researchers tested the possible reason behind how intense hurricanes are generated and run various cloud simulations, increasing the amount of raindrops in clouds. Later, they eliminated the processes induced by the two previously proposed devices and examined whether storm surges were still increasing when aerosol concentrations appeared.
When the processes were shut down, the stimulus still created more intense storm surges with higher aerosol densities.
“That told us that it was not the two previously suggested ideas that were causing changes in convection in our simulations,” Abbott said. “We’ve provided new equipment that should give you a reason to predict stronger hurricanes in parts of the world with high aerosol levels,” he said.
