从蓝到红：中国四级气象预警系统解析
In May, China issued its first red alert of the year. Relentless rain had flooded cities and caused landslides. A red alert is the highest warning in the country's weather system. This four-color system tells the public how severe coming weather will be. Understanding these alerts helps people protect themselves when extreme weather hits. With more frequent heavy rains, knowing the colors is crucial for safety.
The system has blue, yellow, orange, and red levels. Blue means low-impact weather that may cause slight inconvenience. Yellow warns that the weather could become dangerous, so start preparing. Orange signals a high risk, requiring everyone to stay cautious and watchful. Red indicates extreme weather that is happening or may strike soon, demanding immediate protective actions. These colors, like traffic lights, give clear commands to the public.
