沙尘暴天气成因
有利于产生大风或强风的天气形势,有利的沙、尘源分布和有利的空气不稳定条件是沙尘暴或强沙尘暴形成的主要原因。强风是沙尘暴产生的动力，沙、尘源是沙尘暴物质基础，不稳定的热力条件是利于风力加大、强对流发展，从而夹带更多的沙尘，并卷扬得更高。
除此之外，前期干旱少雨，天气变暖，气温回升，是沙尘暴形成的特殊的天气气候背景；地面冷锋前对流单体发展成云团或飑线是有利于沙尘暴发展并加强的中小尺度系统；有利于风速加大的地形条件即狭管作用,是沙尘暴形成的有利条件之一。
沙尘暴形成的物理机制
在极有利的大尺度环境、高空干冷急流和强垂直风速、风向切变及热力不稳定层结条件下，引起锋区附近中小尺度系统生成、发展，加剧了锋区前后的气压、温度梯度，形成了锋区前后的巨大压温梯度。在动量下传和梯度偏差风的共同作用下，使近地层风速陡升，掀起地表沙尘，形成沙尘暴或强沙尘暴天气。

Formation of st storms are required to have 4 conditions.Dust on the ground substance. It is the material basis of the formation of st and sandstorms.Is the second winds. This is the formation of sand-st storm power base, is also capable of long distance transportation of st storms power guaranteed.Three unstable air. It is an important local thermal conditions. Dust storms occur in the afternoon on the importance of end of thermal conditions in the evening.Four is an arid climate environment. Spring st storms occur in the North, and rainfall does not occur over time after st storms is a very good evidence.Spring desert of edge area, e to long-term drought, and surface rare vegetation cover, dang has Gale comes of when surface of st is easy was blowing since and was lost moved, but e to sand grain diameter larger, easily formed hanging moved (suspended moved, is small particles substances guarantee long distance lost moved of necessary), therefore cannot long distance lost moved, this is from st more far of area only st and rare Yang Sha of main causes. If the wind continues for very long, formed of suspended st can be transported far away, area will appear along the sand-st storm; when the winds diminished to a certain extent, sty land, st appears on the weather. If rainfall at this time, it will form the so-called "mud and rain".From sandstorm formed process by needed of 4 a conditions see, loess plateau, and vast of desert and the by man-made factors of damage are is desert of process in the of land, North spring late farming of land and the is construction process in the of based facilities (as Expressway,) for sandstorm of occurs provides has full of substances source; and Spring North area of drought, also makes sandstorm occurs of possibilities enhanced; Gale of proced is a complex of atmospheric phenomenon, main is front activities or Jingwei to circulation adjustment role of results. Thus results both st storm was a variety of complex factors, destruction of nature by human activities leading to increased land desertification, had a very important role on occurrence of st storms, and in recent years the global drought (the reason for this is not yet known) abnormal weather phenomena such as also played an invaluable role in occurrence of st storms. So said human activity only for sandstorms play a role and it cannot be said that st storms are caused by human factors.

Three is not stable air condition. This is an important local thermal conditions. Sandstorm occurs more often in the afternoon that incorporates the evening the importance of thermal condition.
Four is the dry weather environment. Born in the north of the sandstorm multiple spring, and rain after a period of time within a won't happen very good evidence is st storms.
The edge of the desert in the spring, e to long drought, and surface vegetation cover, when there is little wind comes on the surface of the earth is easy to be blowing st and sand, but e to lose move large particle size, is formed not easily movable (suspension movement, it is small particle material guarantee to lose the necessary conditions of long distance move), and therefore can not move long lost, this is far from the st in the st and rare only micrometeorology main reason. If the wind last time is very long, form the st suspended loads can be transported to a very far place, through which areas will appear sandstorm; When the winds weaken to certain degree, floating st will the landing, the st weather will appear. If the precipitation, can form the so-called "NiYu".
The formation process from the four conditions look, the loess plateau and vast desert and by the destruction of the human factors in the process of desertification is in the land of the north, at the end of the spring farming land and in the construction process of infrastructure (such as high speed road, etc.) for the st storm occurrence providing full source material; And the spring drought in the north, and the likelihood of the sandstorm strengthened; The winds generated is a complex phenomenon, mainly is the cold air activities or to the circulation of the regulatory role longitude results. This shows the generation of sandstorm is DuoZhong complex factors results of human activity on the natural world to disruption of the desertification intensifies, st storms happen to have an important role, and in recent years the global drought (the cause isn't yet known) abnormal weather phenomenon also to the st storm occurrence have played an important role. So that human activities for the generation of st storms only play a role, and can't say st storms are caused by human factors.

Sand-st storm is a weather event mainly occurred in the arid and semi-arid regions of the world, which is caused by the sand and st blown into the atmosphere by strong wind. After its occurrence, the atmosphere becomes very sty and the sight distance in the horizontal direction is less than 1000m. Sand-st storm is also a natural event that can cause serious disaster and soil erosion. Consequently, sand-st storm can be a indicator of the degree of desertification.
The occurrence of sand-st storm is mainly controlled by atmosphere circle, weather condition, and characteristics of land cover. However, after its occurrence, human being can do nothing to it. To rece its occurrence frequency and the possible caused disasters, the only practicable way is to improve the condition of land cover. Therefore, researches focus on the relationship between land cover and sand-st storm can not only reveal the occurrence mechanism of sand storm but also provide the theoretical basis to control it. Besides, these researches can also provide theoretical basis for the actions to improve the eco-environment in Northwest China.
