We all know that there are 24 solar terms in a year. Twenty-four solar terms have a very long history in China, which originated in the Yellow River Basin. Different solar terms have different climates. So after which solar term did it get hot?
After which solar term did it get hot? 1 Generally, the weather starts to get hot in long summer, which means that it will start to get hot in summer, and the average temperature will rise above 22 degrees, indicating that summer has begun.
So in 2022, in the long summer, that is, on May 5, the weather will gradually get hotter until the hottest dog days. The long summer in 2022 is on May 5, 2022, 14: 39, Wednesday, March 24 of the lunar calendar.
What month is the summer of 2022?
Beginning of spring, Changchun, beginning of autumn and beginning of winter are the dividing lines of the four seasons, so summer begins in Changchun and ends in Liqiu, and summer in 2022 is from May 5, 2022 to August 6, 2022.
Which month is the hottest in the summer of 2022?
The dog days in the summer of 2022 are the hottest, that is, from mid-July to mid-August, which is the hottest time.
After the summer solstice, although the days are getting shorter and the nights are getting longer, the days are longer than the nights in a day. Every day, the ground absorbs more heat than it emits, and the temperature near the ground is getting higher every day. During the "three volts" period, the heat absorbed by the ground is almost less than the heat emitted, and the weather is the hottest.
After that, the heat absorbed by the ground began to be less than the heat emitted by the ground, and the temperature gradually decreased. Therefore, the hottest time of the year generally appears in the "dog days" from the summer solstice.
After that, the solar terms began to get hot, and beginning of spring began to get warmer. Beginning of spring, one of the 24 solar terms, stands for "the beginning", beginning of spring is the beginning of spring, and beginning of spring is when the sun reaches 3 15 degrees on February 4th or 5th every year.
In China's climatology, beginning of spring is usually defined as a day when the daily average temperature is stable above 10℃ every five days, which is inconsistent with the meaning of beginning of spring in the middle and lower reaches of the Yellow River. In late February, only South China really entered the spring. But this division method is more practical. After beginning of spring, the temperature rose, and most parts of the country began a busy spring ploughing season.
It's getting cold in beginning of autumn. Beginning of autumn is the 13 solar term among the 24 solar terms, and beginning of autumn is on August 8th or 9th every year. "Autumn" means that summer is cool, which means the beginning of autumn. When we arrive in early autumn, the plane trees will definitely start to shed their leaves.
Therefore, there is the idiom "a leaf falls to know autumn". Literally, the word "autumn" consists of "valley" and "fire", indicating the maturity of five grains. Beginning of autumn is the first solar term in autumn, and autumn is a transitional season from hot to cold, and then from cold to cold.
Extended data:
Twenty-four solar terms refer to 24 specific festivals in the China lunar calendar, which indicate the changes of seasons. They are formulated according to the position change of the earth on the ecliptic (that is, the orbit of the earth around the sun), and each one corresponds to a certain position reached by the earth every time it moves 15 on the ecliptic.
Twenty-four solar terms, a supplementary calendar established in the pre-Qin period and completely established in the Han Dynasty, is a knowledge system formed by observing the movement of the sun in a year and understanding the changing laws of the four seasons, climate and phenology in a year.
It divides the sun's annual trajectory into 24 equal parts, and each equal part is a solar term, starting from beginning of spring and ending with severe cold. It is not only a time standard promulgated by successive governments, but also a compass to guide agricultural production. Compass, the compass for people to predict cold, warm, rain and snow in their daily lives, is the crystallization of the long-term experience and wisdom of the Chinese working people.
2016165438+1October 30th, 24 solar terms were officially listed in UNESCO's Representative List of Intangible Cultural Heritage of Humanity. In the field of international meteorology, the 24 solar terms are known as "the fifth invention of China". On May 5, 20 17, the "Twenty-four Solar Terms" Protection Alliance was established in Gongshu District, Hangzhou, Zhejiang Province.
After which solar term did it start to get hot? 3. Which solar term is the hottest in summer? Great summer.
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 heat and severe summer heat, but also different from mild cold and severe cold solar terms. This is a solar term representing 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.
Introduction of summer, summer and summer solar terms
The summer heat is the eleventh of the twenty-four solar terms. It is considered as a slight summer heat when the sun reaches 105 on July 7 or 8 every year. Summer heat, which means hot, is a little hot, not very hot. It means that the weather is getting hotter, but it is not the hottest, and most parts of the country are basically in line with it.
The summer heat is the twelfth solar term in the twenty-four solar terms of the China lunar calendar. On July 23rd or 24th every year, the sun reaches longitude 120. At this time, around the Mid-Autumn Festival, most parts of China are the hottest period of the year, and the climate is characterized by: "Dou refers to C as a great summer heat, and the weather in Sri Lanka is very fierce than a small summer heat, so it is called a great summer heat."
This is the hottest solar term in the year around midsummer. In many areas of our country, the high temperature of 40 degrees Celsius often occurs. In this extremely hot season, heatstroke prevention and cooling can not be ignored.
Summer is the first 14 of the 24 solar terms. Around August 23rd, the sun reached longitude 150. This is a solar term that reflects the temperature change.
According to the "twenty-four solar terms", "go and go again, and the summer heat ends here." It means that the summer heat will end on this day, and the temperature in most parts of China will gradually drop, and the summer heat will soon pass. Especially in northern cities.
