(2/2)🧵
In autumn & winter, warm air traps colder layers below in “temperature inversions.” This stops pollutants like PM2.5 & nitrogen oxides from dispersing, letting smog and haze linger over #Milan and much of Lombardy.🌥🌬💨🏘

What is causing poor #AirQuality in #Milan ?😷

(1/2)🧵
Milan’s poor air quality stems from its spot in Italy’s Po Valley, wedged between the Alps & Apennines. The fertile plains host dense industry & farms, producing 35% of Italy’s crops plus bricks & tiles — but also major emissions.🚜🏭🔥 #MilanSmog
