What does summer mean? Is summer a solar term?

Introduction: There are three summers in the twenty-four solar terms, namely, slight summer heat and great summer heat. Summer means heat, so all three represent heat. Do you know what little summer and big summer mean? Since both mean heat, is it a solar term to have big summer and small summer in summer? If it is linked to heat, I really want to let everyone know which solar term is the hottest in summer. Here are three solar terms in my summer. Come and have a look if you are interested.

What do you mean by a little summer heat and a big summer heat?

Minor Heat

On July 7th or 8th every year, when the sun reaches longitude 105, it is considered as a slight summer heat. "Twenty-four solar terms": "June Festival" ... It is also hot in summer, and it is small at the beginning of the month, big in the month, and still small today. "Summer heat. The ancients thought that the summer heat period was not the hottest time of the year, so it was called summer heat. There is also a solar term ballad: "Little summer is not hot, big summer is three days." It is pointed out that the hottest period of the year has arrived, but it has not reached the extreme hot level. As the saying goes, "the heat is at three volts." The dog days in China generally appear in the summer to the next 28 days, which is the so-called "summer solstice is the first of the night"

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; The words describing crickets in the Book of Songs in July are "Wild July, August, September at home, October in bed." August mentioned in this paper is June in the summer calendar, which is a short time in summer. Because of the heat, crickets leave the field and go to the corner of the yard to escape the heat. In this solar term, the eagle is in the cool high air movement, because the ground temperature is too high.

Major Heat

Summer is the twelfth solar term in the twenty-four solar terms of the lunar calendar. At this time, around midsummer, most parts of China are the hottest period in a year and the fastest growing period of heat-loving crops. The working people of the Han nationality divide the summer heat into three periods: "One period is rotten grass like fireflies; Second, wait for the soil to moisten and cool off the heat; It will be fine when it rains. " There are more than 2000 species of fireflies in the world, which are divided into aquatic and terrestrial species. Terrestrial fireflies lay eggs on hay, and when it is hot, fireflies ovulate, so the ancients thought fireflies were made of rotten grass. The second weather is that the weather becomes sultry and the land is wet. The third kind of weather is frequent thunderstorm, which weakens the heat and humidity, and the weather begins to transition to beginning of autumn.

From the middle and lower reaches of the Yangtze River to Jiangsu, Zhejiang, Jiangxi and other places north of South China, it is hot and rainy, and the rain drops like gold. There are some sayings, such as "Summer rain is as light as silver, and summer rain is as heavy as gold", "Rain in the rain, Ridomi hoards it", "Rain in rainy days, abundant grain and cotton", and "No drought, one acre plus one load". As Heshui Zuo said in his poem, "The sun is shining and the weather is hot, but doing nothing and worrying about flies and mosquitoes. The cloud swells and the arrow scatters gold on the lotus pond. " If it rains around the summer heat, it indicates that there will be more rain in the future. There is a proverb in agriculture that "it rains in summer and water is enough in autumn;" It doesn't rain in summer, and I'm worried that I won't be able to eat water.

The heat is over

Summer is a solar term reflecting the temperature change. "Chu" means to hide and die, and "early summer" means that the hot summer has passed. "Twenty-four solar terms" said: "Go, go, the heat is over." "Chu" means termination, which means that the summer heat is about to pass, the summer heat will end on this day, and the temperature in most parts of China will gradually drop. Being in summer is not only different from mild summer, severe summer, slight cold and severe cold, but also represents the transition from hot to cold.

The poem says: "As soon as the summer heat comes out, it is too late for the autumn wind to send you cool. On a day trip, under the oblique light of the south path, we cut the rice and drove through the horse pond. (Heshui Zuo) ",after the summer heat, except South China and Southwest China; The rainy season is coming to an end in most parts of our country, the precipitation is gradually decreasing, and the rice is ripe and harvested. Especially in North China, Northeast China and Northwest China, we must pay close attention to water storage and moisture conservation. If there is drought during autumn sowing, the sowing date of winter crops will be postponed.

It is not enough to describe the solar terms in summer simply by the beginning of temperature drop. Temperature drop is just one of the phenomena. The reasons behind this phenomenon are as follows: first, the direct point of the sun continues to move southward, and the solar radiation weakens; Second, the subtropical high moved southward by leaps and bounds, and the Mongolian cold high began to itch to try, punching and kicking, showing its edge.

Is there a big summer and a small summer in summer a solar term?

Summer is the solar term of summer, and summer is the solar term of autumn.

The summer solar term means that we are about to enter the autumn with meteorological significance.

When the sun reaches longitude 150, it is the heat of the 24 solar terms of the lunar calendar. Summer is a solar term reflecting the temperature change.

"Chu" means to hide and die, and "early summer" means that the hot summer has passed.

Being in summer is not only different from mild summer, severe summer, slight cold and severe cold, but also represents the transition from hot to cold.

Summer is after beginning of autumn, and autumn is after beginning of autumn, so summer is autumn.

Which solar term is the hottest in summer?

Hot summer is the hottest.

It's a little hot in the summer, not very hot. It's the hottest time of the year in the summer. In summer, the rainy season in the Jianghuai basin is coming to an end, and the temperature rises in summer, entering the summer drought period. However, when North China and Northeast China entered the rainy season, tropical cyclones were active frequently, and the number of tropical cyclones landing in China began to increase.

Everyone knows that it is hot in dog days. Summer heat is generally in the middle of three volts. At this time, most parts of China are in the hottest stage of the year, and the temperature difference across the country is not big.

Just in line with the proverb: "cold is in the March 9 th, and heat is in the middle." The summer heat is relatively mild, as the name implies, it is relatively hot.

Summer is a solar term reflecting the temperature change. In midsummer, the temperature enters a stage of significant change, and it drops day by day, and the summer heat is no longer threatening. But in general, the climate in summer is characterized by hot in the daytime, cool in the morning and evening, large temperature difference between day and night, less precipitation and low air humidity.

The word "early" in summer means termination, indicating that summer is coming to an end; Being in summer is not only different from mild summer, severe summer, slight cold and severe cold, but also represents the transition from hot to cold.

Therefore, compared with the hot summer, we can know that the hot summer is better than the hot summer, and it is also the hottest period of the year.

Why is it so hot in summer?

The heat near the earth's surface mainly comes from the sun. Every year from the summer solstice, the sun shines directly on the tropic of cancer, and the earth's surface gets the most heat. Secondly, during the hot summer, the time difference between day and night is large, which is 13 hours during the day and 1 1 hour at night, with a time difference of 2 hours.

Because the days are long and the nights are short in summer, the heat gained during the day is more than the heat radiated at night, and the income and expenditure are unbalanced, so the temperature accumulation near the surface will become larger and larger, reaching the maximum during the summer solar term.

It is precisely because of the solar altitude angle and heat budget that the summer solar term temperature is the highest.
