解读红色预警：中国四级气象预警系统
When China's meteorological authority recently issued its first red alert of the year for torrential rains, it signaled the highest level of danger. But what exactly does a red alert mean? To understand, we need to look at China's four-tier color-coded weather warning system, which plays a critical role in keeping people safe during extreme weather.
China's weather warning system, established by the China Meteorological Administration in 2007, uses four colors: blue, yellow, orange, and red. Blue represents the lowest level of risk, while red indicates the most severe. Each color corresponds to a specific set of conditions. For rainstorms, a blue alert might be issued when heavy rain is expected within 24 hours, but a red alert means extremely heavy rain that could trigger life-threatening floods and landslides.
