What Is Fujiwhara Effect?
With typhoon Hinnamnor and another tropical storm called Gardo, meteorologists observed a phenomenon called the Fujiwhara Effect.
- Typhoon Hinnamnor, known in the Philippines as Super Typhoon Henry, was a very large and powerful tropical cyclone in Pacific Ocean that impacted Japan and South Korea.
- The Fujiwhara Effect is any interaction between tropical storms formed around the same time in the same ocean region with their centres or eyes at a distance of less than 1,400 km, with intensity that could vary between a depression (wind speed under 63 km per hour) and a super typhoon (wind speed over 209 km per hour).
- The interaction could lead to changes in the track and intensity of either or both storm systems.
- In rare cases, the two systems could merge, especially when they are of similar size and intensity, to form a bigger storm.
