Indian Geography 5 Marks

The recent cyclone on the east coast of India was called “Phailin”. How are the tropical cyclones named across the world? Elaborate.

Directive: Elaborate 5 marks
Introduction

Tropical cyclones are intense weather systems. Naming them facilitates clear identification, tracking, and disaster management, crucially avoiding confusion when multiple systems develop simultaneously.

Body
Global Coordination and Naming Process

The World Meteorological Organization (WMO) and UNESCAP Tropical Cyclone Panels coordinate global naming efforts. The world's oceans are divided into regions, each served by a Regional Specialized Meteorological Centre (RSMC) or Tropical Cyclone Warning Centre (TCWC).

Naming Convention Details

These centres maintain pre-determined lists of names contributed by member countries in their respective regions. Names are used sequentially from these lists, often rotated, and gender-alternated in some regions. Names of particularly destructive cyclones, like 'Phailin' on the east coast, are often retired from future use to avoid insensitivity.

Conclusion

This systematic, globally coordinated naming convention is crucial for effective disaster risk reduction and international cooperation.

The directive 'Elaborate' requires a detailed and comprehensive explanation of the global process of naming tropical cyclones, including the involved bodies and conventions.

Suggested structure

  • Introduction: Brief context of tropical cyclones and the need for naming

  • Purpose and benefits of naming cyclones

  • Global coordination: Role of World Meteorological Organization (WMO)

  • Regional Specialized Meteorological Centres (RSMCs) and Tropical Cyclone Warning Centres (TCWCs)

  • Process of naming: Lists, rotation, and retirement of names

  • Specific example: Naming in the North Indian Ocean region (e.g., Phailin)

Key points

  • Naming facilitates clear communication, tracking, and disaster management, avoiding confusion when multiple systems exist.

  • The World Meteorological Organization (WMO) and UNESCAP Tropical Cyclone Panels coordinate naming efforts globally.

  • The world's oceans are divided into regions, each served by a Regional Specialized Meteorological Centre (RSMC) or Tropical Cyclone Warning Centre (TCWC).

  • These centres maintain lists of names contributed by member countries in their respective regions.

  • Names are used sequentially from the pre-determined lists, often rotated, and gender-alternated in some regions.

  • Names of particularly destructive cyclones are often retired from future use to avoid insensitivity.

Common mistakes

  • Only focusing on the Indian context (e.g., IMD) without explaining the global framework.

  • Not detailing the role of WMO or RSMCs in the naming process.

  • Confusing the naming process with the classification or intensity scales of cyclones.

  • Failing to explain the rationale or benefits behind naming cyclones.

Difficulty: Medium — The question requires specific factual knowledge about international meteorological organizations (WMO, RSMCs) and their established protocols for naming tropical cyclones, which goes beyond general awareness.
