| Satellite image of Fujiwara effect wherein you can see two cyclones just like orbiting each other |
I learned that Fujiwhara effect, named after Sakuhei Fujiwhara, is a type of interaction between two nearby cyclonic vortices, causing them to appear to "orbit" each other.When the cyclones approach each other, their centers will begin orbiting cyclonically about a point between the two systems due to their cyclonic wind circulations. The two vortices will be attracted to each other, and eventually spiral into the center point and merge. When the two vortices are of unequal size, the larger vortex will tend to dominate the interaction, and the smaller vortex will orbit around it. The effect is often mentioned in relation to the motion of tropical cyclones, although the final merging of the two storms is uncommon. The effect becomes pronounced in these storms when they approach within about 1,500 km (900 mi) of each other and are at tropical storm strength or stronger.
I want to know more about the other possible reactions of two normal cyclones whether would it be possible for them not to combine and if that happens what would be the possible factors that affected such reaction. Moreover, I also want to know if only two cyclones are involved and what would be the possible result if these two cyclone have opposite direction of movement, would they still pull each other for them to combine?
I appreciate the fact that changes in the atmospheric pressure is one of the many factors that builds or constructs this phenomenon.
I can apply my learnings and insights in being prepared in case these weather system occurs.
