Hurricanes can be Prevented Using Air Bubbles
Researchers reveal that hurricanes can be prevented using air bubbles, according to a study conducted on March 19, 2018.
The collision of masses of cold and warm air generates tropical hurricanes. Sea surface temperature greater than 26.5 degree Celsius is an important factor that can lead to hurricane. Nowadays, sea surface temperature is increasing due to the changes in climate. 26.5 degree Celsius is the critical temperature at which evaporation is sufficient to promote the development of hurricanes. As a solution to this problem, many ideas were proposed by people, which included seeding clouds with sea salt to increase reflectivity and reduce sea surface temperature. However, those proposed ideas were not successful.
In this study, researchers try and test a method called as bubble curtain. Through a perforated pipe lowered in the water, bubbles of compressed air is supplied. When these bubbles rise, they take the cold water deep in the ocean to the surface of the ocean and cools the warm surface water. Grim Eidnes, senior research scientist said, “Our initial investigations show that the pipes must be located at between 100 and 150 meters depth in order to extract water that is cold enough.”
This method will help in bringing down the temperature of sea surface and prevent the occurrence of hurricanes. The method of bubble curtains has been used in Norway for many years now. Also, it will not be an obstruction to shipping and can be executed at both small and large scales.
