The warming of the oceans is related to the appearance of the oceans. hurricanesso it is often heard about the possibility of theories. artificially cool the sea to weaken the occurrence of these atmospheric phenomena. However, is this really possible? A group of scientists performed related tests in laboratory simulations and showed that: it would be “useless” even if the sea could be cooled.
Even if we had the infinite power to artificially cool the oceans enough to weaken a hurricane, the benefits would be minimal. The study, led by scientists from the Rosenstiel School of Earth, Atmospheric and Marine Sciences at the University of Miami (UM), showed that: For starters, the amount of energy required to cool the sea and weaken a hurricane before it reaches land makes it a highly inefficient solution. To mitigate such disasters.
“The main implication of our study is that large quantities of artificially cooled water are needed to cause a modest attenuation of hurricane intensity before landing,” said lead author of the study, James Hlywiak, a graduate of the Rosenstiel School of the Um.
“Also, weakening this density by irrelevant amounts doesn’t necessarily mean that it will also reduce the chance of internal damage. While any amount of weakening before land is a good thing, it makes more sense to focus directly on compliance strategies“It’s like strengthening infrastructure, improving the efficiency of evacuation procedures, and advancing science around the detection and forecasting of impending storms.”
The authors used a combination of air-sea interaction theories and a highly complex computer model of the atmosphere to provide a scientific answer to the question of whether it is possible to artificially cool the ocean to weaken hurricanes.
In computer simulations, they cooled areas of the ocean by up to 260,000 square kilometers. (greater than the state of Oregon and equivalent to 21,000 cubic kilometers of water) up to 2 degrees Celsius. Even in tests with the largest cooling area, simulated tornadoes weakened by only 15 percent.
Moreover, The amount of energy extracted from the ocean to make this small reduction is equivalent to more than 100 times the amount consumed in the entire United States in 2019.
“It should probably be clear that the main conclusion of our paper, namely trying to weaken hurricanes, is pointless,” said David Nolan, professor of atmospheric sciences at the UM Rosenstiel School and lead author of the study.
“Nevertheless, numerous hurricane modification theories are frequently in the media, and even patent applications are filed every few years. We are delighted to be able to add something to the scientific literature addressing this topic.”
The study, titled ‘Aimed ocean cooling to weaken tropical cyclones is futile’, is published in the journal Nature. Nature Communication Earth and Environment.
