Good Evening Friends, We are posting today’s 10pm Current Affairs Quiz . Interstingly though sometimes atmospheric forces can exceed the counterclockwise Fujiwhara effect and cause a net clockwise rotation around each other. For this occurrence to take place, the distance between the two tropical cyclones must be within 1 400 kilometers (870 miles). Fujiwhara Effect has been used to describe the tendency of two nearby tropical cyclones to interact with each other. The Fujuwhara effect basically describes how … The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described the effect.

Binary interaction is seen between nearby extratropical cyclones when within 2,000 kilometres (1,200 mi) of each other, with significant acceleration occurring when the low-pressure areas are within 1,100 kilometres (680 mi) of one another. Fujiwhara effect The tendency of two nearby tropical cyclones to rotate cyclonically about each other as a result of their circulations' mutual advection . The Fujiwhara effect causes the TCs to rotate around each a common point in a counter-clockwise manner. This definition differentiates tropical cyclones from extra tropical (midlatitude) cyclones that exhibit a cold-core in the upper troposphere and often form along fronts in higher latitudes. The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described the effect. The Fujiwhara effect, sometimes referred to as Fujiwara interaction or binary interaction, is when two nearby cyclonic vortices orbit each other and close the distance between the circulations of their corresponding low-pressure areas.
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 The Fujiwhara Effect: When hurricanes collide. A Fujiwhara effect may not always mean that both storms will change course. Two big cyclonic systems forming at the same time could also influence each other's wind systems and lead to pushing and pulling. Questions?
