A huge sandstorm in Mongolia killed six people. What are the possible reasons for the raging sandstorm?

The occurrence of sandstorms scares many people. After all, the strong winds are mixed with yellow sand, and the sky is filled with only yellow sand and strong winds, which is very scary. This sandstorm has hit Mongolia and has caused many deaths and disappearances. So how did such a terrible sandstorm form? Generally, there are two factors contributing to it. First, in terms of temperature, the temperature is uneven, precipitation is scarce, and the weather is dry. On the other hand, there are strong winds. 1. From the underlying surface, it is the influence of temperature.

In Mongolia, the weather temperature in the northwest has increased, generally five to eight degrees Celsius higher than in other regions. In addition, most areas of Mongolia have relatively little precipitation. Such harsh surface conditions, This brings great advantages to the occurrence of sandstorms. The surface conditions are dry, which is conducive to the occurrence of sand and dust weather, but there is another hard condition, which is windy weather, which Mongolia also meets. 2. The occurrence of strong windy weather.

Affected by the Mongolian cyclone, strong winds occurred in northern Xinjiang, central and western Gansu, most parts of Inner Mongolia, and northern North China. The average wind force has reached level 6 to level 8. This kind of The emergence of strong winds also provides good thermal and dynamic conditions for sand and dust weather. Under the combined action of wind and sand, sandstorms are formed. 3. Impact of climate.

Dry weather and strong winds are the conditions for the formation of sandstorms, but the spread of sandstorms also requires certain conditions. Now many plants in the north have not sprouted, and the coverage is very low. . The low coverage of this kind of vegetation cannot reduce the customs. Once strong winds arrive, the sand is easily moved up, so many sandstorms occur in March. Over the past seventy years, the average number of sand and dust days in March has been 2.4. This data is very high, but we also hope that people will take good protection in the face of sand and dust storms.
