Essay on Haze Haze is a combination of fog and haze.

Due to the deterioration of air quality, haze weather phenomena have increased and the hazards have worsened.

Many areas in China incorporate the haze weather phenomenon into fog as a disastrous weather warning and forecast.

Collectively referred to as "haze weather".

Smog, as the name suggests, is fog and haze.

But fog is fog, haze is haze, and there is a big difference between fog and haze.

Sulfur dioxide, nitrogen oxides and respirable particulate matter are the main components of smog. The first two are gaseous pollutants, and the last particulate matter is the culprit that aggravates haze weather pollution.

They combine with the fog, making the sky instantly gray.

The English abbreviation of particulate matter is pm. What Beijing monitors is pm2.5, which is pollutant particles less than 10 microns in diameter.

The particles themselves are both a pollutant and a carrier of toxic substances such as heavy metals and polycyclic aromatic hydrocarbons.

Sources of toxic particulate matter in cities: such as car exhaust; waste produced by burning coal for heating in winter in the north; waste gas emitted from industrial production, etc.

As air quality deteriorates, haze weather phenomena increase and the hazards worsen.

Many areas in China incorporate the haze weather phenomenon into fog as a disastrous weather warning and forecast.

Collectively referred to as "haze weather".

In fact, fog and haze are very different from a certain perspective.

For example: when fog occurs, the air is humid; when haze occurs, the air is relatively dry, and the relative humidity of the air is usually below 60%.

The reason for its formation is the phenomenon of air mixed erosion due to a large number of extremely fine dust particles, smoke particles, salt particles, etc. floating evenly in the air, making the effective horizontal visibility less than 10km.

The symbol is "∞".

The diurnal changes in haze are generally not obvious.

When there are no major changes in the air mass and the air mass is relatively stable, it will last for a long time, sometimes lasting more than 10 days.

Due to weather phenomena such as haze, light fog, sandstorms, blowing sand, floating dust, and smoke, the effective horizontal visibility is less than 10km due to the influence of a large number of extremely fine dust particles or smoke particles floating in the air.

Sometimes it is difficult for meteorological professionals to distinguish.

It is necessary to comprehensively analyze and judge factors such as weather background, sky conditions, air humidity, color and smell, and satellite monitoring to draw correct conclusions. Moreover, the weather phenomena of fog and haze can sometimes be converted into each other.

Haze is harmful to the human body when inhaled into the human respiratory tract, and severe cases of long-term inhalation can lead to death.

Of course, in the face of this terrible natural weather, we also need some self-protection. Open windows less often in hazy weather; such as: wearing a mask when going out; drinking more Tong platycodon tea; taking appropriate vitamin D supplements; eating a light diet and drinking more water, etc., these can all be done

Effectively protect against the invasion of smog.
