Tips
culture
中国气象局 (CMA) sits at the national level, with 省气象局 and 市气象局 operating at provincial and city levels. They issue the color-coded warnings: 蓝 (blue), 黄 (yellow), 橙 (orange), 红 (red) — standard language you'll hear in any Chinese weather app or news broadcast.
usage
The 市 prefix marks it as city-level; drop it and you get the generic 气象局. Because weather warnings are ubiquitous on Chinese media, 气象局 appears in daily news far more often than most other bureaus.
