Some standard content:
ICS07.060 National Standard of the People's Republic of China GB/T19201—2006 Replaces GB/T19201—2003 Grade of tropical cyclones Grade of tropical cyclones Issued on 2006-05-09 General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China Standardization Administration of China Implemented on 2006-06-15 This standard replaces GB/T19201—2003 Grade of Tropical Cyclones. The Beaufort Wind Force Scale was used as a reference during the revision. Compared with GB/T19201-2003, this standard adds two more grades: strong typhoon and super typhoon. Appendix A of this standard is an informative appendix. This standard is proposed by the China Meteorological Administration This standard is issued by the Policy and Regulations Department of the China Meteorological Administration. This standard was drafted by the National Meteorological Center of the Meteorological Bureau of ten countries. GB/T19201—2006 The main drafters of this standard are Qian Chuanhai, Gao Shuanzhu, Xu Yinglong, Lu Shan, Zhang Shoufeng, Liu Zhenkun, Gu Hua, Zhang Ling, Yao Xuexiang, and Xue Jianjun. This standard was first issued in June 2003 1 Scope Tropical cyclone level Sanshangjia Districtx BoPortalcn GB/T19201—2006 This standard specifies the level and classification principles of tropical cyclones in my country's forecast responsibility area. This standard applies to the business and scientific research of tropical cyclones in my country's forecast responsibility area. The business regulations on tropical cyclones can be implemented with reference to this standard. 2 Terms and definitions The following terms and definitions apply to this standard. 2.1 Tropical cyclonetropicalcyclone A general term for non-frontal vortices with organized convection and definite cyclonic circulation that are generated on tropical or subtropical ocean surfaces, including tropical depressions, tropical storms, severe tropical storms, typhoons, severe typhoons and super typhoons. Wind force levelwind scale A level determined according to the degree of influence of wind on objects on the ground (or sea surface), used to estimate the size of the wind. Note: The commonly used wind force level was formulated by the British Beafort in 1805, so it is also called the "Bcaufort wind force level (Bcaufort scale)", which is divided into 13 levels from 0 to 12. Since 1946, the wind force level has been expanded to 18 levels (0~17). The Beaufort wind force scale table is shown in Appendix A. 2.3 Sea-level pressuresea-levelpressure The pressure value calculated from the station pressure to the mean sea level. 2.4 Mean wind speedmeanwindspeed The average wind speed in a given period of time. Note: Mean wind speed is a statistic of wind speed. In the observation specification, the average wind speed from 2Ⅲin before the exact time to the exact time is taken as the wind speed at the exact time. GB/T19201—2006 Tropical cyclone intensitytropicalcyolane intensity三上佳区x BoPortalcn The most average wind speed or the lowest sea level pressure near the center of the tropical cyclone bottom layer (near the ground or near the sea surface, the same below). Responsibleforecastingarea The area where meteorological stations at all levels prepare and issue tropical cyclone forecasts and warnings according to service responsibilities or administrative divisions: Note: my country's forecast responsibility area refers to the area between 105°E and 180°E, north of the equator. 2.7 Maximum wind maximumwind The maximum value of the average wind speed near the bottom center of a tropical cyclone within a given period of time or a certain period. Note: The maximum wind speed is usually expressed in wind scale. 3 Abbreviations The following abbreviations apply to this standard. sTsSevere tropical storm (severetropiaal stormSTY severe typhoon.

See Table 1 for details.
