What do you mean by three waves of weather? Is it foggy in Sanlang weather?

1. In the weather forecast, the icon of three wavy lines is dense fog.

2. Weather forecast icons are internationally used, especially some of the most basic forecast icons. China Meteorological Bureau has also specially produced weather graphic symbols to standardize dozens of forecast icons including sandstorms and freezing rain.

However, with the weather phenomenon becoming more and more complicated and changeable, new symbols emerge one after another. In the standard weather graphic symbols of China, there are at least 13 kinds of light related to rain, some turn from moderate rain to heavy rain, and some turn from heavy rain to heavy rain, but they all look like water drops under a cloud.
