Typhoons are classified into four types: medium to strong, very strong and super strong. A super-strong wind refers to a typhoon with a maximum wind speed of 54 meters per second or more. Typhoon Hinnamnor is classified as a super strong typhoon as it has been whipping up winds of 150 miles per hour and rushing back toward the islands of Japan and Korea.

As wind speeds continue to climb, it will approach Japan’s Sakishima Islands and Okinawa’s main island between Saturday and Sunday. Later, it will also pass Taiwan and the coast of mainland China.
The Fujiwhara Effect
Typhoon Hinnamnor illustrated a phenomenon as the Fujiwhara Effect. The typhoon pulled a weaker storm and controlled the weaker storm.
According to National Weather Service, the Fujiwhara Effect happens when two storms get close to one another to form a shared centre, driven the two storms to revolve around the central point. Afterward, if one of the storms is stronger than the other, the weaker one will likely break apart in this effect. If the storms are strong enough, they may join or past one another and continue on their course.
Typhoon Hinnamnor, a powerful hurricane moving toward Japan, demonstrated a phenomenon called the Fujiwhara Effect this week where it literally pulled in a weaker storm and overpowered it!
