What is summer heat?

Slight summer heat is "slight heat", which means that although we can already feel the heat of the weather at this time, it has not reached the hottest time of the year, just the beginning of a hot summer day. Monsoon climate is the main feature of China climate. Monsoon climate is a mixture of continental climate and maritime climate. Summer is affected by the warm and humid air flow from the ocean, which is hot, humid and rainy. The high temperature in monsoon climate is basically the same as that in rainy season, and the rain and heat are in the same period, which is beneficial to crop growth. In summer, the weather is hot and thunderstorms are frequent, which is the season when everything is crazy.

Although light summer is not the hottest season in a year, it is followed by the hottest summer. There is a folk saying that "it is hot in summer, but hot in midsummer, and the weather will become more and more sultry and humid, and the summer heat will make people have nowhere to hide." In the hot summer, it begins to enter the dog days. There is no cool wind on the earth, and there will be heat waves in the wind. During the shallow summer, it is midsummer in southern China, and some places have entered the season with the most thunderstorms, often accompanied by strong winds and heavy rains. As summer is light, people are ready for the heat.

What is the first solar term of the 24 solar terms?

It is 1 1 of the 24 solar terms in China, and it is also the fifth solar term in summer. The time of light summer is July 7 or 8 every year, and it is light summer when the sun reaches 105. So this year's light summer is July 7. Summer heat, which means hot, is a little hot, not very hot. Slight summer heat is relative to great summer heat. The ancients thought that this was not the hottest time of the year, so it was called a slight summer heat. Slight summer heat means that the weather is getting hotter, but it is not the hottest.

In ancient China, the summer heat was divided into three periods: "First, it was warm and windy; Second, wait for crickets to live in space; The third waiting eagle began to crow. " In summer, there is no cool wind on the earth, and all the winds carry heat waves; Because of the heat, cricket also left the venue at this time and went to the corner of the yard to escape the heat and enjoy the cool; At the same time, the eagle will be in the cool high air movement because the ground temperature is too high.

What does the heat represent?

The arrival of summer means that most parts of western and southern South China have entered the season with the most thunderstorms. Thunderstorm is a disastrous weather phenomenon, often accompanied by strong winds, heavy rain and sometimes hail, which is easy to cause disasters and must be prevented. The number of rainstorm days in July and August can account for more than 75% of the whole year, generally about 3 days. Mountain torrents often occur in places with large relief, and even cause mudslides. However, in the eastern part of South China, due to the frequent control of subtropical high, the weather is sunny and hot, and after experiencing a slight summer heat, it began to enter the summer drought period. The climatic characteristics of drought in the east and waterlogging in the west in most parts of southern China have a great relationship with agricultural abundance and waterlogging, so we must take measures to ensure the harvest of drought and waterlogging as soon as possible to minimize the harm.

The arrival of light summer represents the monsoon rainy season, with obvious increase in precipitation and relatively concentrated rainfall; South China, Southwest China and Qinghai-Tibet Plateau are also in the southwest monsoon rainy season from the Indian Ocean and the South China Sea. However, under the control of subtropical high, the middle and lower reaches of the Yangtze River are generally hot and rainy, with frequent droughts in summer, which has a great impact on agricultural production. It is very important to store water as soon as possible to prevent drought. An agricultural proverb says, "Rain on a rainy day is rice in a pot". Although the precipitation brought by thunderstorms, tropical storms or typhoons at this time is very beneficial to the growth of crops such as rice, it sometimes has adverse effects on dry crops and vegetables such as cotton and soybeans.
