What are the symbols of the three waves on the bar?

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

Weather forecast icons are international, 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 complex 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.

The importance of weather forecast:

The main contents of weather forecast are the future rain, maximum and minimum temperature, wind direction and wind force and special disastrous weather in a region or city. As far as China is concerned, meteorological stations can accurately predict the location and intensity of natural disasters such as cold waves, typhoons and rainstorms, and can directly serve industrial and agricultural production and people's lives.

Weather forecast is based on meteorological observation data, applying the principles and methods of meteorology, dynamic meteorology and statistics to make a qualitative or quantitative forecast of the weather conditions in a certain area or a certain place in the future. This is an important goal of atmospheric science research. It is of great significance to people's lives.

Nowadays, when people go out, they can decide whether to bring rain gear by listening to or watching the weather forecast. In the past, they had to worry about the weather.
