Regarding the cause of fog at the end of February, according to meteorological experts, in recent days, Ho Chi Minh City has had unseasonal rain, causing air humidity to increase. This morning (February 22), the sky was gloomy, cloudy, weak sunshine, weak wind, in addition, high air humidity caused suspended substances in the air (also known as fine dust particles) to condense and form an opaque fog. The thick fog shows that there is a lot of dust and suspended substances in the air, which will affect health. Therefore, people need to wear masks and glasses when going out.
