The definition of Fujiwhara Effect. When the cyclones approach each other, their centers will begin orbiting cyclonically about a point between the two systems. Extratropical cyclones typically engage in binary interaction when within 2,000 kilometres (1,200 mi) of one another, while tropical cyclones typically interact within 1,400 kilometres (870 mi) of each other.
