中国天气红色预警的历史与含义
In recent days, China issued its first red alert for rainstorms this year, as heavy rains flooded cities and triggered landslides across multiple regions. For many residents, seeing a red alert on their phones is a clear signal of extreme danger. But what exactly does this highest-level warning mean, and how did such a system come to be? China's meteorological authorities use a four-tier color-coded warning system to tell the public about coming weather threats. Understanding its history and rules can help people better prepare for nature's fury.
The color-coded warning system was officially introduced in 2007 by the China Meteorological Administration (CMA). Before that, weather warnings were less structured and often confused the public. The new system used blue, yellow, orange, and red to represent increasing levels of danger, with red as the most severe. This idea was inspired by international practices, such as those used in the United States and Japan, but tailored to China's specific needs. Over time, it has become a key part of the country's disaster prevention efforts.
