The Fujiwara Effect: When Cyclones Collide

The video explains the Fujiwara effect, a meteorological phenomenon where two nearby cyclones interact and potentially merge. Named after Sakai Fujiwara, this effect involves cyclones moving in circles around each other, with the possibility of merging into a larger cyclone. Historical examples include interactions between Super Typhoon Valore and Typhoon Parma, and Hurricane Hillary and Hurricane Irwin. The effect is observed in both tropical and extra tropical cyclones, with specific distance thresholds influencing their interaction and acceleration. Predictability of these interactions depends on factors like cyclone size and atmospheric conditions.

What is the Fujiwara effect primarily associated with?

• The movement of cyclones in a straight line

• The dissipation of cyclones

• The formation of a single cyclone

• The interaction of two nearby cyclones

In which hemisphere do cyclones move counterclockwise due to the Fujiwara effect?

• Northern Hemisphere

• Eastern Hemisphere

• Southern Hemisphere

Which of the following is an example of the Fujiwara effect?

At what distance do tropical cyclones begin to merge under the Fujiwara effect?

• 300 kilometers

• 650 kilometers
