Explanation:

The Fujiwhara effect can turn two cyclones into one mega cyclone.

• The Fujiwhara Effect is any interaction between tropical storms formed around the same time in the same ocean region with their centres or eyes at a distance of less than 1,400 km.

• It is characterised by an intensity that could vary between a depression (wind speed under 63 km per hour) and a super typhoon (wind speed over 209 km per hour).

• When two hurricanes spinning in the same direction pass close enough to each other, they begin an intense dance around their common centre.

• If one hurricane is a lot stronger than the other, the smaller one will orbit it and eventually come crashing into its vortex to be absorbed.

• The interaction could lead to changes in the track and intensity of either or both storms systems.

• In rare cases, the two systems could merge, especially when they are of similar size and intensity, to form a bigger storm.

Hence both statements are correct.
