Tropical Cyclone Interaction in the Western Pacific
When two tropical cyclones are within close proximity to each other, they will typically start a rotation around a common center. This interaction, called the Fujiwhara Effect, may be occurring in the image loop above. Typhoon Bolaven approaches Typhoon Tembin, and the distance between the two reaches a minimum on 23 August, after which time Tembin moves west and Bolaven moves northwest. Subsequent to Bolaven’s recurvature over the Korean peninsula, Tembin moves northward into midlatitudes as well.
