Ocean warming may increase the frequency of extreme rain storms.

According to scientists from NASA, the rapid climate change, which causes warming in tropical oceans, can lead to a significant increase in the frequency of extreme rain storms by the end of the century.

A research team led by Hartmut Aumann from the NASA Jet Propulsion Laboratory in California found that extreme storms — those that produce at least 3 millimeters of rain per hour over a 25-kilometer area — are formed when the sea surface temperature was higher than 28 degrees Celsius.

They also found that for every 1 degree Celsius, 21% more storms form than ocean temperature.

In accordance with currently accepted climate models, it is predicted that with a steady increase in carbon dioxide in the atmosphere (1 percent per year), the surface temperature of the tropical ocean may rise by as much as 2.7 degrees Celsius by the end of the century.

The researchers explained that if this happens, we can expect that by this time the frequency of extreme storms will increase by as much as 60 percent.

Although climate models are not ideal, such results can serve as a guide for those who want to prepare for the potential impacts that climate change can have.

“Our results provide a quantitative estimate and a more visual representation of the effects of projected warming of the oceans,” said Aumann.

“More storms means more floods, more structural damage, more crops, etc., unless mitigating measures are taken.”

For a study published in Geophysical Research Letters, the team examined 15-year data from NASA's atmospheric infrared sounder (AIRS) tool from tropical oceans to determine the relationship between mean sea surface temperature and the onset of heavy precipitation. storms.
