Sorry buddy a bad news if you're living in the northern part of China, here's something worth keeping on your radar before winter arrives: air pollution could become a serious headache again this season.
China's Ministry of Ecology and Environment has reported the formation of a “super El Niño” event in the eastern Pacific in September. The event developed rapidly and is expected to become the strongest El Niño since systematic monitoring began.
So, what does a weather phenomenon happening thousands of kilometres away have to do with the air you're breathing in Beijing, Tianjin or other northern Chinese cities?
Quite a bit, potentially.
El Niño is a climate phenomenon caused by unusually warm sea temperatures in the tropical Pacific. It can affect weather patterns thousands of kilometres away, including the strength of winter winds in East Asia.
When those winds weaken, they may not be strong enough to blow away pollution from factories, traffic and other sources. Instead, the pollutants can accumulate near the ground, creating prolonged periods of smog.
OK, forget the boring weather science. What does this mean in plain English?
Apparently, this year the regular El Niño gobbled up Mario's Super Mushroom and levelled up into a SUPER El Niño. And no, that is not going to be fun for us., especially for those living in northern China.
The stronger event could bring weather conditions that make it harder for pollution to disperse. In laymen's terms? More smog, worse air quality, and potentially more days when you'll want to think twice before going for that outdoor run.
And this isn't just a theoretical concern. During the winter of 2023–2024, a widespread haze episode lasted 16 days, affecting around 2.7 million square kilometres of China, more than 28% of the country's land area. Nearly 100 cities experienced severe pollution.
The air is so bad that if you go outdoor, you would becoming literally a human air filter.
If you're living in northern China, don't wait until the sky turns grey and the air starts smelling like someone has been burning the entire neighbourhood to start paying attention.
Check the AQI and PM2.5 readings daily, particularly during still, hazy weather. (Psst... you might want to cross-check the reading with international air-quality monitoring platforms too. Don't ask me why. )
Keep a suitable PM2.5 grade air purifier at home, especially if you live in a city
that regularly experiences winter smog.
Adjust outdoor exercise when pollution levels are high. That outdoor run can wait until the air improves.
Consider a well-fitting particulate respirator, such as a properly fitted N95 or equivalent, when outdoor pollution is severe. Ordinary cloth masks offer limited protection against fine particles.
The bottom line? A super El Niño doesn't automatically mean another pollution disaster, but it could stack the weather conditions against us.
If you've lived in China long enough, you probably know the drill: winter is coming, and checking the air quality might become just as important as checking the temperature before heading out.
Stay informed, protect your lungs, and don't let a beautiful blue-sky day convince you that the next few months will necessarily be the same.
