GB/T 32935-2016 in English

Standard formulation background and technology evolution analysis

1. Development background:Tropical cyclones are one of the major natural disasters in the world, and their monitoring and warning are crucial to meteorological operations and scientific research. However, there are differences in the classification of tropical cyclones in different countries and regions, which makes it difficult to unify and compare data. For this reason, the "Global Tropical Cyclone Classification" standard came into being.

2. Technology evolution:This standard is based on the expansion of the Tropical Cyclone Scale (GB/T 19201), adding detailed classifications for the South Pacific, the waters near Australia and the North Indian Ocean. At the same time, it is combined with the standards of the World Meteorological Organization (WMO) Tropical Cyclone Regional Specialized Meteorological Forecast Center to ensure global coordination and consistency.

Implementation recommendations

a. Data collection and processing:It is recommended that meteorological departments of all countries uniformly adopt this standard for tropical cyclone classification and establish a data sharing mechanism.

b. Early warning system optimization:In combination with regional characteristics, optimize early warning thresholds and response measures. For example, in the North Atlantic region where hurricanes frequently occur, the monitoring and emergency preparedness of Category 5 hurricanes should be strengthened.

c. Popular science education:Through public education, improve the society's awareness of different tropical cyclone levels, especially popularize typhoon defense knowledge in disaster-prone areas.
