Explanation:

Only statement 2nd is correct.

Fujiwhara Effect

• When two hurricanes or cyclones, spinning in the same direction, when brought close together, they begin ‘an intense dance around their common centre, this interaction is called the Fujiwhara effect.

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

• If one hurricane’s intensity overpowers the other, then the smaller one will orbit it and eventually crash into its vortex to be absorbed.

• If two storms of similar strengths pass by each other, they may gravitate towards each other until they reach a common centre and merge, or merely spin each other around for a while before shooting off on their own paths.

• In rare instances, the two ‘dancing’ cyclones, if they are intense enough, may merge with one another, leading to the formation of a mega cyclone capable of wreaking havoc along coastlines.

• The occurrence of the Fujiwhara effect also makes cyclonic systems harder to predict.

• The rising frequency of this unusual effect, attributing it to a rapidly warming world and the subsequent heating of ocean waters.

• A warming climate is giving rise to stronger cyclones, and thus, increasing the possibility of the Fujiwhara effect.

Hence option 1st is correct.
