What role do weather patterns have in the development and strength of cyclones?
Model Answer The Fujiwhara effect refers to the interaction between two cyclones or hurricanes when they come close enough to spin around a common center, creating a dramatic and intense "dance" between them.

Model Answer
The Fujiwhara effect refers to the interaction between two cyclones or hurricanes when they come close enough to spin around a common center, creating a dramatic and intense “dance” between them. This effect occurs when the cyclones are close enough to influence each other’s rotation. As per the National Weather Service (NWS), these cyclonic interactions are becoming more frequent, largely attributed to global warming, which heats ocean waters and enhances cyclone activity.
Implications of the Increasing Occurrence of the Fujiwhara Effect on Coastal Regions
- Damage to Infrastructure: The Fujiwhara effect can cause significant damage to coastal infrastructure due to powerful winds, storm surges, and flooding. For example, in 2021, the interaction between Cyclone Seroja and Cyclone Odette in the Indian Ocean led to widespread infrastructure damage in Australia.
- Threat to Life: Stronger storms resulting from the Fujiwhara effect bring more powerful winds, heavier rainfall, and larger storm surges, increasing the risk of fatalities. The 2022 Fujiwhara interaction of Typhoon Hinnamnor and Tropical Storm Gardo in the western Pacific Ocean resulted in fatalities in South Korea, primarily from drowning.
- Loss of Livelihood: In rare cases, when two cyclones merge, they can form a mega-cyclone capable of devastating coastal economies, especially in agriculture and tourism. For instance, Superstorm Sandy impacted the livelihoods of many people in the U.S. due to its storm surges and extensive flooding.
- Ecosystem Disruption: The Fujiwhara effect can also disrupt coastal ecosystems by causing stronger winds and larger waves, leading to physical damage to mangrove forests, coral reefs, and estuary habitats, all of which are crucial to the local biodiversity and economy.
- Forced Migration: The increasing frequency of the Fujiwhara effect could lead to forced migration in vulnerable coastal areas, contributing to internal migration challenges and overwhelming local infrastructure.
Given its unpredictable nature, it is essential to enhance disaster preparedness and develop effective early warning systems to mitigate risks associated with the Fujiwhara effect.

Introduction:
Cyclones are intense circular storms that originate over warm tropical oceans and are characterized by low pressure at the center, strong winds, and heavy rainfall. The formation and intensity of cyclones are influenced by several climatic factors such as sea surface temperature, atmospheric moisture, and wind patterns.
Factors Contributing to Cyclone Formation
Climatic Conditions and Cyclone Intensity
Conclusion:
The interplay between oceanic and atmospheric conditions largely determines the formation and intensity of cyclones. With climate change altering many of these factors, cyclones are becoming more frequent and intense, posing increasing challenges for coastal communities. Effective mitigation and adaptation strategies are crucial to minimize the impact of these climate-driven disasters.
