Understanding of graupel in ancient times

The ancients knew about graupel a long time ago. Poetry of Xiao Yaqian means "If it rains or snows, gather the dimension first". Zheng Xuan of the Eastern Han Dynasty commented: "It will rain heavily, but it will be slightly warmer at first. When the snow is warm and angry from top to bottom, it is called phlegm. It snows when it is cold for a long time. " Hey, roll things into balls. In other words, it was supposed to snow, but it became like snow because of the temperature, and there may be heavy snow next.

Of course, this is not for popular science, but for paving the way, in order to vividly say the original intention behind it, which is the so-called analogy in rhetoric. In the words of Confucius, a scholar in the Tang Dynasty, this poem "said that the king's politics and religion were autocratic. If it rained heavily a few days ago, its snow would gather first and then turn into heavy snow. It's snowing. "

Qu Dajun, a A Qing dynasty man, has talked about similar problems. He said that Guangzhou "has frost and no snow, and the frost is thin and invisible", and he also said that "even if there is slight ice, it should be considered as snow, or if there is slight snow, it should be considered as ice. People can't tell ice from snow. " Qu Dajun, a native of Panyu, wrote "Yue Xin Yu" by "taking an examination, taking its ambition, setting an example and collecting its evidence".
