• 202601 = 1st typhoon in 2026

A tropical cyclone.Tropical Storm When (maximum wind force near the center) you get code, and there is no code in the Nameless stage.

Who is Code?

Typhoon code of the Northwest Pacific and S SeaChina Meteorological Agency负责 (依据我国业务规定) , JMA (Japan) (JMA) 作为世界气象组织指定的区域专业气象中心 (RSMCE京) 负责international code 和命名的分配. 两套code绝大多数情况一致, 偶有分歧 (对某个系统是否达到Tropical Storm判定不同) , 所以极少数年份会出现中日code错位.

Code and Name Relationship

• code201409 – Accurate, Indiscriminate, Suitable for Data Recovery
• The name: Rammasun (Rammasun) ——来自140个The name的循环命名表, 方便传播

同一个The name会隔几年重复使用 (除非除名) , 但code永不重复. 所以查History时, 用code最准确: TyphoonSays的The History Box支持code, 中文名, 英文名三种方式检索.
