1. The Fujiwhara Effect is a weather phenomenon where two nearby tropical cyclones orbit each other, named after Japanese meteorologist Sakuhei Fujiwhara, who described it in 1921. This interaction, which can happen when storms are within about 900 miles, leads to various outcomes, including the storms rotating around a common center and then separating, or one storm absorbing the other. The stronger storm usually dominates, but the interaction can unpredictably shift a storm's intensity and track, making forecasts more complex.
