Why are there so many sandstorms in Yinchuan this year? ! ? ! ? Let no one live.

It is understood that the sandstorm weather in Ningxia is seasonal, mainly from March to May every year, and April is the high incidence period. According to the regulations of the meteorological department, sandstorm, sand blowing and floating dust are collectively called sandstorm weather. According to meteorologists, the temperature in our region has risen rapidly recently, with the highest temperature rising to 25℃. In addition, since the winter of 2008, the precipitation in Yinchuan is less, and the surface water evaporates rapidly with the high temperature, which makes it possible to raise sand. In addition, the recent weak cold air activities are frequent, but the wind is not very strong, which leads to more dusty weather in Yinchuan recently.

Experts say that dusty weather can cause harm to people's eyes, nose, throat, skin and other direct contact parts. In dusty weather, the incidence of allergic rhinitis, pharyngitis and asthma has generally increased. In addition, some floating dust is brought by the wind from far away, which is likely to carry some pathogenic bacteria or viruses. If you don't pay attention to protection, it will also cause human-related diseases. Experts believe that dust is the most harmful to the human respiratory system, and the public should not be underestimated. In particular, the elderly, infants and people with poor resistance to respiratory allergic diseases should stay indoors in dusty weather, close doors and windows and try to stay away from dust sources. Pay attention to wearing masks or taking other protective measures when traveling or working outdoors.

It is reported that the World Meteorological Organization has decided on the theme of this year's commemoration, calling on people to understand the relationship between weather, climate and air, and their impact on human health, so that people can face up to the problems of climate change and air pollution. To this end, Ningxia Meteorological Bureau will carry out a series of colorful commemorative activities on the basis of daily opening-up and street publicity activities of popular science bases, including: holding a meteorological and medical and health meteorological science popularization report meeting in Ningxia Medical College to commemorate World Meteorological Day; Widely carry out meteorological disaster prevention and mitigation science propaganda into the classroom, into the fields, into community service stations, into the construction site, into the bus, into the train and other activities.
