预警
How to Understand
预警 refers to a warning or alert given in advance of a potential danger or problem. It is commonly used in contexts such as weather forecasts, security threats, and disaster preparedness. Unlike a general warning, 预警 implies proactive awareness and preparation.
The character 预 (yù) means 'pre-' or 'before,' indicating something that happens in advance. 警 (jǐng) means 'alert' or 'warning.' Together, they convey the idea of an early alert system or precautionary measure.
预警 is widely used in public safety, environmental monitoring, and crisis management. In China, it is often seen in weather reports, where authorities issue warnings for typhoons, floods, or extreme temperatures. It is also used in business and technology to signal potential risks before they escalate.
