Typhoon Parma (left) and Melor (right) interacting with each other in the Philippine Sea on October 6, 2009.. The Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiw(h)ara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices move around each other and close the distance between the circulations of their corresponding low-pressure areas.
The Fujiwhara effect – which describes the rotation of two storms around each other – is one of meteorology's most exquisite dances. It's most common with tropical cyclones such as typhoons or ...
Where an extratropical cyclone encounters another extratropical cyclone (or almost any other kind of cyclonic vortex in the atmosphere), the two may combine to become a binary cyclone, where the vortices of the two cyclones rotate around each other (known as the "Fujiwhara effect").
A cluster of tropical activity has developed across the Pacific Ocean, as three features battle for dominance and hold the potential for a phenomenon called the Fujiwhara Effect to occur.
Small wobbles in a tropical cyclone's track can occur when the convection is distributed unevenly within its circulation. This can be due to changes in vertical wind shear or inner core structure. [7] Because of this effect, forecasters use a longer term (6 to 24 hours) motion to help forecast tropical cyclones, which acts to smooth out such ...

- Sakuhei Fujiwhara is the first to note that hurricanes move with the larger scale flow, and later publishes a paper on the Fujiwhara effect in 1921. [40] 1920 – Milutin Milanković proposes that long term climatic cycles may be due to changes in the eccentricity of the Earth's orbit and changes in the Earth's obliquity.
