{International: Euphrates News} NASA warned of the arrival of "very destructive" storms as global temperatures rise.
"Hurricane Irma entered the Caribbean this week as a Category 5 storm, killing at least nine people so far, leaving two million Puerto Ricans without electricity and around Barbuda island," NASA said in a statement. The hurricane is not over yet, and the storm is expected to reach Florida in a few days. "
Some media mistakenly reported that Irma was classified as a Category 6 hurricane. There is currently no such degree, but with climate change, warmer oceans are expected to increase energy to storms, causing a higher proportion of hurricanes.
"One can make Irma and many other historic storms all over the world classified as Tier 6," says Radley Horton, a climatologist at the Lamont Doherty Earth Observatory in Colombia. Class 6 argument has reinforced the fact that high wind speeds can cause disproportionate damage. "
Thus, for example, the difference in potential wind damage between a 6-speed 190-mph and a Category 5 hurricane at 156 mph , Would be much greater than the difference between a hurricane class 3 at 111 miles per hour and a hurricane class 1 at 74 miles per hour.
However, since the winds of 156 miles per hour have the ability to completely destroy an area, would it really be helpful to add a higher degree of it? Susanna Camargo, who studies hurricanes in Lamont Doherty, believes that the designation of Grade 6 would be useful, not alone in this belief. "While Irma storms are rare in the Atlantic, they are not rare in the Western North Pacific, The Saffir Simpson scale works well there. " But as global temperatures rise, the hurricane's maximum intensity is expected to rise, which could justify adding more grades to the scale in the future, says Timothy Hall, who puts hurricane risk models at NASA's Goddard Institute for Space Studies.
"In the future, there may be storms more severe than anything we have seen before, because the higher limits of severity have become higher, and if these storms are very dangerous more frequent, it may be appropriate to create a new distinction between devastating storms and very destructive."
Although most predictions suggest that climate change will bring us stronger storms like Irma in the future, Horton warns, "That is not certain."
These powerful storms are rare enough that scientists do not know what is the "natural" number of storms of this force. Historical records are not much back, and hurricane-measuring equipment is relatively new, so scientists find it difficult to find a clear direction in those limited data.
Although scientists predict that rising sea surface temperatures will cause more severe storms, Horton says other factors, such as changes in wind conditions, can cause severe hurricanes.
Meteorologists have discussed adding a new degree to the scale in the past, but for the foreseeable future they will have to continue the current scale from 1 to 5. Scientists studying weather and climate are accustomed to dealing with imperfect storm risk measures; the Saffir Simpson measure measures wind speed Harvey Harvey was just a third-class cyclone, but Texas sank in a devastating amount of rain, causing some of the worst storm damage in history.
"Concentration on wind speed, however important, risks ignoring a more important point, the wind speed is easy to measure and predict, but the storm storm - rising ocean waters around the hurricane - is one of the most dangerous aspects of the hurricane, unpredictable The wind alone depends on the magnitude of the storm, the shape of the coast, and the bottom of the seabed. "
"While simple indicators - such as wind speed - can have enormous value, they can not fully identify local risks," he said, "This is an argument for a more complex and accurate way to measure the hurricane risk."
