In this windy weather, affected by cold air, the air formed a cold vortex, which was small in scope but strong in intensity. There is a strong updraft in front of the cold vortex and a strong downdraft behind it. The relative scale of cold vortex is small, which belongs to secondary circulation. Beijing is just behind the cold current. With the continuous and strong development of cold vortex, windy weather lasts for a long time and the wind is strong, which makes you messy in the wind. In the process of dusty weather, besides the strong wind brought by cold air, dust sources are also needed. During this windy weather, there was no obvious sandstorm weather in the stadium, so the external transportation volume was relatively small.

When going out in windy days, you should try to avoid using light vehicles to avoid overturning due to insufficient gravity. You should try not to ride a bike in this weather. Riding against the wind is not only tiring, but also easy to be blown up by the wind when riding in the crosswind. Please remember to wear a mask and sunglasses when you go out to avoid dust damage to your eyes and respiratory system. Please pay attention to fire prevention in windy and dry weather. Don't smoke or make a fire outside.
