What does it mean to raise sand?

Sand blowing weather refers to the weather phenomenon caused by local or nearby dust being blown by the wind.

When the sand blowing weather occurs, the visibility of the air will drop obviously, and the sky will appear cloudy yellow. The wind is strong in sand-blowing weather, which affects the visibility between 1 km and1km.

As a sandstorm disaster, sand blowing does not happen in all windy places, but only in those areas with dry climate and sparse vegetation. Sand blowing mostly occurs in April-May every year. Mainly distributed in the western and northern regions, Inner Mongolia, Tibet and Xinjiang are the most serious.

When using extended data to record sandstorm, the horizontal visibility should be in the range of 1.0- 10.0km, and the visibility levels in different directions are often inconsistent, sometimes having little effect on the vertical visibility. When people are outdoors, dust particles often give people a feeling of hitting their faces, and doors and windows sometimes crack. People walk against the wind, and dust and fine sand strongly stimulate people's eyes.

When there is strong dust weather, doors and windows should be closed in time to maintain indoor humidity. Outdoor sports should be avoided as much as possible, especially for special groups such as the elderly. Use a dust-proof and dust-filtering mask when going out to reduce the inhaled dust. When going out in windy weather, you should avoid walking or staying under trees or billboards to avoid the danger of being hit by falling objects.
