Will dusty weather become the norm?

For this problem, meteorologist Rao Qin Xiao made it clear that it would not happen. In the long run, under the background of global warming, the activities of wind and cold air in winter are weakened, and the dynamic conditions of sand formation are also weakened. According to perennial statistics, March-May in spring is the season with frequent sandstorms, and the sandstorm process accounts for about 80% of the whole year.

It is predicted that after the end of April, with the gradual increase of precipitation and temperature in the northern region, it is beneficial to the growth of vegetation, the underlying surface conditions of dust will gradually improve, and the influence scope and intensity of dust will tend to weaken.

"However, sandstorms in northern China mainly occur in spring, and the sandstorm weather will remain active for more than a month in the future. This year, the overall surface conditions of Shayuan are not ideal. If the weather conditions are favorable, there may be some dusty weather. " Rao Qin Xiao added.

Extended data:

Compared with previous years, the reasons for the increase of dusty weather this year

There are indeed many sandstorms this year, which have happened seven times so far. This is mainly because the surface conditions of sand sources such as Mongolia and western Inner Mongolia are more deviated than normal this year. In these areas, precipitation is scarce, the temperature is warmer, and the surface is dry and bare, which provides sufficient material basis for the occurrence of sandstorms.

Coupled with the frequent alternation of cold and warm air since March this year, the strong wind formed by the cold, high pressure, warm and low pressure weather system provided favorable dynamic conditions for the occurrence of dust weather.
