Cyclone Tracking and Monitoring

Cyclone Tracking and Monitoring: Meteorological Definition and WMO Framework

Cyclone Tracking and Monitoring is the systematic process of detecting, tracking, and predicting the movement and intensity of tropical cyclones, as defined by the World Meteorological Organization (WMO). According to the WMO, a tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over warm tropical waters, with sustained winds of at least 39 mph (63 km/h). The WMO's Tropical Cyclone Programme (TCP) is the authoritative framework for cyclone tracking and monitoring, providing guidelines for the detection, tracking, and prediction of tropical cyclones worldwide.

💡 Key Insight: The WMO's TCP is based on the WMO's Technical Regulations, which specify the criteria for the classification and naming of tropical cyclones.

The TCP is based on the WMO's Technical Regulations, which specify the criteria for the classification and naming of tropical cyclones. The TCP also establishes the procedures for issuing warnings and advisories to affected countries, as well as the standards for data exchange and coordination among meteorological agencies. The WMO's Regional Specialized Meteorological Centres (RSMCs) and Tropical Cyclone Warning Centres (TCWCs) are responsible for monitoring and predicting tropical cyclones in their respective regions, using a range of observational and modeling tools.

💡 Key Insight: Cyclone Tracking and Monitoring is not simply a matter of predicting the path of a storm, but rather a complex process that involves understanding the underlying atmospheric and oceanic conditions that drive tropical cyclone development and intensification.

There are currently five RSMCs that are responsible for tropical cyclone forecasting and warning dissemination in the Indian Ocean and the South-West Indian Ocean:

  1. The India Meteorological Department (IMD) serves as the RSMC for the North Indian Ocean, which includes the Bay of Bengal and the Arabian Sea.
  2. The Météo-France serves as the RSMC for the South-West Indian Ocean, which includes the area south of the equator and west of the 80th meridian east.
  3. The Australian Bureau of Meteorology serves as the RSMC for the Australian region, which includes the area north of the 10th parallel south and east of the 90th meridian east.
  4. The National Meteorological Centre of the United States serves as the RSMC for the North Atlantic and the Eastern Pacific Ocean.
  5. The Japan Meteorological Agency serves as the RSMC for the Western Pacific Ocean.

Each RSMC has its own data exchange mechanisms in place to facilitate the sharing of meteorological data and warnings with other RSMCs and national meteorological services. The RSMCs use a range of data sources, including satellite imagery, radar, and surface weather observations, to track and predict the movement and intensity of tropical cyclones.

💡 Key Insight: The RSMCs use a range of data exchange protocols, including the Global Telecommunication System (GTS) and the Tropical Cyclone Warning Center (TCWC) network, to disseminate warnings and advisories to national meteorological services and other stakeholders.
