What are the climatic characteristics of mango's solar terms?

Phenological characteristics:

In ancient China, the fifth day was called the first phase, so a solar term (about15th day) was also called the third phase. The "three phases" of each solar term are named according to the climate characteristics and some special phenomena at that time, which are used to express the characteristics of the weather at that time concisely and clearly. The solar terms of mango were divided by the ancients into: the first time mantis was born, the second time _[jú] began to sound, and the third time was silent.

When a mantis was born, it laid eggs in the late autumn of last year. When it came to the awning season, it felt the birth of Yin Qi and broke its shell and gave birth to a little mantis.

Specific meaning:

The second queen _[jú] The first song: _ refers to the shrike, a small bird of prey. Shrike, who likes shade, began to appear in the branches and sing in the shade.

What is the third stage of the awning? Three kinds of animals are used to represent climate characteristics.

Third-class anti-tongue silence: Anti-tongue is a bird that can imitate the songs of other birds, but at this time it stopped singing because it sensed the appearance of Yin Qi.

1, temperature

During this period, except for the Qinghai-Tibet Plateau and the northernmost part of Heilongjiang, people in most areas can generally feel the summer heat. Nenjiang River is located in the north of Heilongjiang Province. During the 30 years from 197 1 to 2000, the hottest day (37. 1℃) appeared in the awning period.

In June, whether in the south or the north, high temperature weather above 35℃ may occur, and high temperature weather above 40℃ may also occur in Huanghuai area and the eastern part of northwest China, but it is generally not a continuous high temperature. In China's southern provinces of Taiwan Province, Hainan, Fujian, Guangdong and Guangxi, the average temperature in June is around 28℃. If the air humidity is high before the thunderstorm, it is really stuffy and hot. Sometimes it is necessary to issue a high temperature forecast to the public to remind people to prevent heatstroke, air conditioning disease and acute gastroenteritis.

Step 2 precipitate

The Yangtze River is in the ear sowing season, and the Huanghuai Plain is about to enter the rainy season. If there is continuous rain, strong wind and hail before and after ear planting, and the wheat can't be harvested, threshed and stored in time, it will lead to the lodging, grain dropping, germination and mildew of the ear, "rotten wheat field" and destroy the crops in front of us.

Behind the scenes, the monsoon rain belt in southeastern South China is stable, which is the season with the most precipitation in a year. The middle and lower reaches of the Yangtze River have entered the rainy season one after another, with more rainy days, more rainfall, less sunshine and sometimes lower temperatures.

In the awning season, rice, cotton and other crops grow vigorously and need a lot of water, and moderate plum rain is very beneficial to agricultural production; In the years when the plum rains are too late or too little or even "empty plum blossoms", crops will be threatened by drought. However, if the rainy days are too early, too many rainy days and too few long-term rainy days, it will also have a negative impact on agricultural production, especially if the rainfall is too concentrated or heavy rain will cause floods.

Southwest China has also entered the rainy season of the year since June. At this time, the hail weather in the southwest and western plateau areas began to increase.
