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 effect is named after Dr. Sakuhei Fujiwhara who was the chief of the Central Meteorological Bureau in Tokyo, Japan, shortly after the First World War. In 1921, he wrote a paper describing the ...
When two hurricanes collide, the phenomenon is called the Fujiwhara effect. If two cyclones pass within 900 miles of each other, they can start to orbit. If the two storms get to within 190 miles ...
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.
The storm's passage over land resulted in notable weakening, though Isbell remained of hurricane-strength. During the afternoon of October 15, the low that had formed the previous day induced a northward turn of the cyclone and directed it toward North Carolina, a result of what is known as the Fujiwhara effect.

The main Pilger tornado accelerated in speed and rapidly intensified to mid-range EF4 strength as it struck another farmstead on 848th Road. The farmhouse was swept away with winds of 182 mph (293 km/h). As the tornado began its rope-out phase, it gained speed and interacted with the developing Wakefield tornado, undergoing a Fujiwhara effect ...
Fujiwhara effect. On Tuesday afternoon, as the storm approached the Bay Area, the system developed two "eyes," or areas of low pressure, resulting in a "doubled-barreled blow" to San Francisco and ...
That data shows the El Reno–Piedmont tornado and a separate cyclonic tornado, originating from the same mesocyclone, rotating in a counterclockwise fashion about a single common center (in a demonstration of the Fujiwhara effect) for several minutes, before merging at approximately 4:35 p.m. [26]: 3033 The second satellite came just minutes ...
