Could It Happen That 2 Hurricanes Combine to Create a Mega-Storm?

Ever wonder if two hurricanes could collide to form one mega-storm? Well, the answer is yes and its called the Fujiwhara effect. Named after a Japanese meteorologist, Dr. Sakuhei Fujiwhara, who first described this type of storm in 1921.

The Fujiwhara effect occurs when two tropical storms or hurricanes rotate in close proximity, coming close enough to form one giant storm. According to an article by abc13.com, “If the centers of the systems come within 680 miles of each other, though, they could actually merge into one larger storm. The conditions have to be just right for that to happen, though.”

This video, shared on the Storm Shield App channel on YouTube, explains all about this effect and its potential. With the hurricane season being more active this year and producing higher category storms, it is not without concern that this effect could happen eventually. “Albeit common, the Fujiwhara effect is very unstable,” Oreste Reale, a research meteorologist at NASA’s Goddard Space Flight Center, explained to abc13.com.

“The two vorticity maxima must be at a certain distance and reach some sort of temporary balance. If one of the two has a drastic change – for example, the lower levels become affected by drag so that the storm enters a rapid weakening – the Fujiwhara effect rapidly vanishes,” shares abc13.com.

Some good news according to www.worldatlas.com is that although this effect is a possibility, it could also serve to divert the original path of both storms away from its original targets, thus avoiding catastrophic effects such as the recent storms by Harvey, Maria, and Irma.
