How to use symbols to represent weather phenomena?

The symbols of the weather are as follows:

1, symbol of weather phenomenon

When observing a certain weather phenomenon, meteorological observers should record the corresponding symbols in the "Weather Phenomenon" column of the observation record book of the day, except for a few phenomena, and also record the starting and ending time. Based on these symbols, combined with the intensity, coexistence and some characteristics of weather phenomena, a group of symbols that can be filled in weather maps are called cartographic symbols.

2. Weather graphic symbols

In order to make it easy for the public to understand and identify, a set of images and graphs representing weather phenomena has been formulated for TV or other public media.
