Source: The post is based on the article “Perfect storm: What is the Fujiwhara Effect?” published in Down To Earth on 28th November 2022.
What is the News?
Meteorologists were mesmerized by Typhoon Hinnamnor as it provided a textbook example of a phenomenon known as the Fujiwhara Effect.
What is the Fujiwhara Effect?
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 the 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.
Identified by: The Fujiwhara effect was identified by Sakuhei Fujiwhara, a Japanese meteorologist whose first paper recognising the Fujiwhara cases was published in 1921.
