Fujiwhara Effect:
Two cyclonic storms are predicted to form in the Bay of Bengal, with a potential Fujiwhara interaction.
- The Fujiwhara Effect (also named as the Fujiwhara interaction or the binary interaction) occurs when two nearby cyclones or hurricanes interact with each other.
- It was first described by a Japanese meteorologist, Dr. Sakuhei Fujiwhara, in 1921. The phenomenon was thus named after him.
- During the Fujiwhara interaction, the centers of the two cyclones involved in the phenomenon begin to mutually orbit in a counterclockwise direction about a point between the two cyclones.
- The position of the point is dependent on the intensity and relative mass of the cyclonic vortices.
- The smaller cyclone involved in the Fujiwhara Effect moves at a faster rate than the bigger one about the central point.
- The Fujiwhara Effect might lead the two cyclones to spiral into the central point and merge with each other, or it might trigger the development of a larger cyclone.
- The effect might also divert the original path of one or both the cyclones.
