Why the question:
Super typhoon Hinnamnor, the strongest tropical cyclone of the year, was hurtling towards Taiwan from the western Pacific Ocean. Another tropical storm called Gardo was moving towards Hinnamnor from its southeast. As the two approached each other, they started a dance around the central line between them, showcasing a textbook example of what is known as the Fujiwhara Effect.
Key Demand of the question:
To write about differences between tropical and extratropical cyclone and the Fujiwhara effect.
Directive word:
Compare and contrast – provide for a detailed comparison of the two types, their features that are similar as well as different. One must provide for detailed assessment of the two.
Structure of the answer:
Introduction:
Begin by defining a cyclone and its types.
Body:
First, write about the differences between tropical and extratropical cyclone on various parameters – formation, source of energy, central cores and impact etc.
Next, write about the Fujiwhara effect and its impact on cyclones.
Conclusion:
Conclude by summarising.
