Hurricanes lasting longer, making them extremely dangerous as wind speeds that can accelerate 180 miles per hour are not considered slow. Yet tropical cyclones that involve hurricanes have become languid. This may augur bad news for people staying in their way.
A study published in journal Nature concentrates on what is known as translation speed, which evaluates how speedily a storm is operating on an area from Miami to the Florida Panhandle. Between 1949 and 2016, tropical cyclone translation speeds have decreased 10 percent worldwide according to the study. The storms are lingering over places for a longer time span.
Lingering hurricanes can spell trouble as Texans learned last year when hurricane Harvey impede over the state engendering destructive flooding and billions of dollars of damage. The storm drizzled more than 30 and 50 inches of rain in two and four days in some places respectively.
In a report released by Harris County involving Huston discovered that Harvey’s rainfall transcended all the flooding events in the American history since 1899. The extensively high rainfall was due to the sluggish movement of the storm said Deanna Hence, a professor of atmospheric sciences at the University of Illinois at Urbana-Champaign. This rainfall fell in the same place for a long period of time he added.
James Kossin, a climate scientist with the National Centers for Environmental Information at the National Oceanic and Atmospheric Administration examined the alterations in translation speeds, therefore tapping into a global data set on prior tropical storms.
