What is the weather symbol for three horizontal bars with a tick?
Three horizontal bars with a hook are the symbols of blowing sand, as shown in the figure below. Blowing sand refers to a weather phenomenon caused by local or nearby dust being blown up by the wind.
When sand blows, visibility drops significantly, and the sky is cloudy and yellow when it occurs. In the north, it is easy to appear in spring. The wind is strong during blowing sand weather, which affects the visibility between 1 km and 10 km.
