What does dusty weather mean? Causes and protection methods

Strictly speaking, sand and dust weather is divided into four categories: floating dust, blowing sand, sandstorms and strong sandstorms. So, what does dusty weather mean? How was it formed?

What does floating dust mean?

Floating dust is a weather phenomenon caused by sand or soil particles suspended in the atmosphere, reducing horizontal visibility to less than 10km. Floating dust is caused by fine particles such as dust floating in the air after a sandstorm or blowing sand occurs in a remote or local area. Commonly known as "falling yellow sand", when it appears, distant objects appear khaki and the sun appears pale or light yellow. It appears roughly before and after the passage of cold air.

Causes of dust weather: Soil and sand particles on the bare ground can be carried into the air by wind and turbulence, and carried to non-bare ground by air currents. Sand and dust weather occurs in arid and desert areas due to strong winds and strong turbulence. Sand and dust particles are carried to high altitudes and transported to distant places with high-altitude air currents. At the source of sand and dust, sandstorm walls tens of meters high can form, causing extremely high concentrations of sand and dust particles in the atmosphere in some places. How to protect yourself from dusty weather

When dusty weather occurs, you should try to avoid going out and close doors and windows in time when at home, especially for patients with chronic bronchitis, the elderly and children who have relatively weak resistance. If you don't pay attention to protection in the dusty sky, old diseases will relapse or other diseases will occur.

If you go out, it is best to use a dust mask and glasses as protection. This can effectively block the irritation of the respiratory tract from wind and sand, and reduce or prevent dust from entering the respiratory tract and lungs.

After traveling home, people who travel can rinse their mouths with water and clear their nasal cavities to reduce the chance of infection. They can also drink more water to speed up the discharge of metabolic waste from the body.
