扬沙

Sand storm and dust devil in spring in northern parts were extremely frequent.

春季北方扬沙和沙尘暴天气异常频繁；

The sandstorm, blowing sand, and floating dust day Numbers assume the obviously reduced tendency.

沙尘暴、扬沙、浮尘日数呈明显减少趋势。

The sky glowed Saturday and a thin dusting of sand covered Beijing.

北京周六天空灰蒙蒙的，到处是薄薄的扬沙尘土。

Reduce the time on outdoor activities and try to avoid riding a bicycle outside in Sand-Dust days.

扬沙天气应减少户外活动时间并尽量避免骑自行车出行。

There are different relationships between abnormal low visibility event and floating dust, sandstorm and flying-dust respectively.

浮尘、沙尘暴和扬沙与低能见度事件的相关程度是不同的。
