Guangzhou has ice particles from Conghua. What are these so-called ice particles?

Ice particles are due to the fact that it snows. If the temperature is high, some snowflakes may melt into water droplets, and when encountering strong airflow, they will be taken back into the air to be refreezed, and then fall to the ground.

Ice particles are transparent small balls or irregular solid deposits, which are relatively hard and generally rebound when they touch hard ground. If it is broken, only the ice shell, with a diameter less than 5mm, often falls from nimbostratus, stratocumulus or stratocumulus, and the gas layer is relatively stable.

In most parts of the world, ice particles generally only appear in a short time and do not accumulate in large quantities. However, in the eastern United States and southeastern Canada, before the severe storm weather scale system, hundreds of miles of warm air flowing out of the northern Gulf of Mexico will be cooled into dense air for a period of time.

In these areas, ice particles can accumulate to 2-5 cm thick. The effect of mass accumulation of ice particles is different from that of snow. One major difference is that the same volume of snow is obviously heavier, so it is more difficult to clear. In addition, compared with the same volume of newly fallen snow, a large number of ice particles need to take more time to melt.
