What weather symbol is the black triangle?

Long live. In the weather forecast of China Meteorological Bureau, the black triangle represents hail. When the temperature dropped to a certain extent, the water vapor in the air was supersaturated, so it rained. If you encounter cold air without condensation nuclei and water vapor condenses into ice or snow, it is snowing. If the temperature drops sharply, it will form a bigger ice mass, which is hail.
