With the deterioration of air quality, the increase of haze weather is seriously harmful. Recently, many areas in China have entered haze weather phenomena together with disastrous weather warning predictions. Collectively referred to as "haze weather. In fact, in some aspects, it is very different from haze weather, for example: when there is fog and the air is humid, the air that appears haze is relatively dry, and the air is usually less than 60% The relative humidity is caused by a large amount of very fine dust, smoke particles, and salt floating evenly in the air. Therefore, the effective horizontal visibility is less than 10KM. The symbol "∞" is generally not obvious. . When there is no big change in the air quality, the air mass becomes more stable and lasts longer, sometimes lasting 10 days or more. The haze, fog, and haze in the air change from day to day to sandstorms, blowing sand, and dust. , Smoke and other weather phenomena are caused by plankton and a large number of very fine dust particles or smoke particles that affect the effective horizontal visibility of less than 10 kilometers. It is sometimes difficult for professionals in the meteorological department to distinguish the weather background and must be combined with comprehensive analysis and judgment. , the influence of factors such as sky, air humidity, color, smell, and satellite monitoring, in order to draw correct conclusions, haze weather phenomena can sometimes cause serious harm to the human body and cause death after inhalation. >
