It means that there are more thunderstorms during the summer. Breaking the dike in the great summer means that the rain is very heavy during the great summer, which has washed away the bank and caused floods and so on.
during the light summer, from the southern part of China, the thunderstorm season gradually entered from south to north. This is a severe weather phenomenon, which is often accompanied by lightning, thunder, storms and even hail, causing floods and other effects. Sometimes, it does harm to crops and is not conducive to the healthy growth of crops.
The summer heat is one of the twenty-four solar terms, and it is also the last solar term in summer. At this time, the sun is located at 12 degrees of the yellow meridian, which is the period with the most sunshine and the highest temperature in China. Because it is in the "dog days" period, most parts of the country are dry and lack of rain, and the temperature in many areas is above 35 degrees, and it is also prone to disasters such as droughts, floods or strong winds.
Weather characteristics of the great summer heat:
In the middle and lower reaches of the Yangtze River north of South China, such as Jiangsu, Zhejiang and Jiangxi, it is hot and rainy, and the rain drops like gold. There is a saying that "the light summer rain is like silver, and the heavy summer rain is like gold", "It rains in the rain, and Ridomi is hoarded", "It rains in the rainy days, and the grain and cotton are abundant", and "It is not affected by drought, and one acre is added with one load".
Just like Heshui Zuo's poem says, "It's sunny in the dog days, and it's hot in the summer, so you're bored by flies and mosquitoes. When the drums rise in the clouds, the arrows will sprinkle gold on the lotus pond. " If it rains before and after the summer heat, it indicates that there will be more rain in the future. There is an agricultural proverb that "there is rain and rain in the summer, and autumn water is enough;" There is no rain and little rain in the summer, and you are worried about eating water.
In the western part of South China, although high temperature occurs most frequently, rain is the most abundant and thunderstorms are the most common, which is the season with the most thunderstorms. There is a proverb here that says, "There is no drop in the east flash, and the west flash can't walk."
It means that in the summer afternoon, if lightning appears in the east, it won't rain here; if lightning is in the west, it will rain soon, and it's too late to escape.
according to the heat or not, there are many agricultural proverbs to predict the weather in the later period: for example, in the short term, there are "a big summer heat, and the fields will rest;" The summer is cool and the water is full of ponds "; The mid-term indicates "great summer heat, cool after autumn"; Long-term predictions include "the summer heat is too hot, and there will be no frost for four months", "the summer heat is not hot, the winter is not cold" and "the summer heat is not hot and the winter will rot".
