预警数据

Alert Independent API

Alert has an independent API, see v3 Alert API.

In v2.6, you can get alert data by adding the alert=true parameter to any weather data interface:

Alert information is synchronized with the Central Meteorological Bureau and is returned by alert area and administrative division. Grid spatial resolution does not apply. For details, see Variable Coverage.

编码规则

预警代码取自 code 字段，预警代码的前两位是预警信息类型，预警代码的后两位是预警级别。举例："code": "0901”，可以分解出结构：预警类型编码＋预警级别编码，于是我们得到雷电蓝色预警。
