Concise Definition: A thick, oppressive smog or haze caused by a combination of fog and severe air pollutants.

In a Nutshell: 雾霾 (wùmái) isn't just “foggy weather.” It's the specific term for the dense, greyish-yellow air pollution that famously blanketed many Chinese cities, especially during the 2010s. The word evokes feelings of concern for health, frustration with the environment, and the tangible, visible evidence of rapid industrialization. It's a modern word that captures a major chapter in China's recent history.

雾 (wù): This character means “fog” or “mist.” The top radical 雨 (yǔ) means “rain,” clearly linking it to an atmospheric, weather-related phenomenon. It refers to natural water vapor in the air.

霾 (mái): This character means “haze.” It also features the rain radical (雨), but the bottom component gives it the sense of something obscuring or “buried.” It typically refers to haze caused by fine dust, smoke, or pollutants suspended in the air.

When combined, 雾霾 (wùmái) describes a hybrid phenomenon where natural fog (雾) traps and mixes with man-made pollutants (霾), creating a much more severe, persistent, and harmful type of air pollution than either component alone.

A Symbol of an Era: For much of the 2010s, 雾霾 (wùmái) was more than a meteorological term; it was a daily topic of conversation, a major public health crisis, and a symbol of the environmental cost of China's economic boom. Checking the PM2.5 (air quality) index on one's phone became as routine as checking the weather. The term dominated news headlines and social media, sparking widespread public debate and pressuring the government into action.

Comparison to “Smog”: The closest Western concept is “smog” (a portmanteau of smoke and fog), which accurately translates the term. However, the cultural weight is different. While cities like Los Angeles or London have famous historical smog events, wùmái in China became a nationwide, unifying experience that affected hundreds of millions of people simultaneously. It spurred a massive public awakening about environmental protection and led to the widespread adoption of face masks and air purifiers long before the COVID-19 pandemic. The fight against wùmái became a national project, often referred to as a “war on pollution” (向污染宣战).

Daily Conversation: People use 雾霾 (wùmái) to talk about the daily air quality, make decisions about outdoor activities, and express concern for the health of children and the elderly.

News and Formal Reports: The media uses 雾霾 to report on air quality levels, visibility, and government initiatives to combat pollution. You'll often hear it in weather forecasts (天气预报).

Social Media: On platforms like Weibo, 雾霾 is a common topic for complaints, sharing photos of the low visibility (or a rare clear, blue sky), and sometimes as a metaphor for a gloomy or unclear situation (e.g., “my future feels like it's shrouded in wùmái”).

Connotation: The term is almost exclusively negative. It implies dirtiness, health risks, and a low quality of life. The opposite, a clear day, is celebrated as a “blue sky” (蓝天, lántiān).

Smog vs. 雾霾: A Difference in Scale and Social Impact: While “smog” is a perfect translation, remember that for many Chinese people, 雾霾 carries the weight of a recent, intense, and collective national experience. Using the word shows an awareness of a major social and environmental issue in modern China, not just an observation about the weather.
