How much do you know about Lixia? What's the origin of Lixia's name? Lixia and Xiazhi literally mean that summer is coming. If you don't know much about Lixia, let's take a look at this essay compiled by Xiaobian. I believe you will have a different understanding of Lixia after reading it.
What's the difference between the beginning of summer and the solstice
The time span and solar angle are different
The beginning of summer is the seventh solar term in the 24 solar terms of the lunar calendar. The first solar term in summer means the official beginning of Mengxia. When the sun reaches 45 degrees of the Yellow longitude, it is the beginning of summer. Dou refers to the southeast, which is called Lixia. Everything grows up here, so it is named Lixia. The beginning of summer is on May 5 or 6 every year.
The summer solstice is one of the 24 solar terms, on June 21 or 22 of the Gregorian calendar. On the day of the summer solstice, the sun moves to 90 degrees of the Yellow longitude (the summer solstice, currently in Gemini), and the position where the sun is directly on the ground reaches the northernmost end of the year, almost directly on the Tropic of cancer. At this time, the day time in the Northern Hemisphere reaches the longest in the whole year.
The beginning of summer just marks the beginning of summer. At this time, the climate is not very hot. Therefore, the summer solstice is much hotter. There is a folk saying that the summer solstice is not hot. The dog days begin from the summer solstice. After the summer solstice, the temperature of the whole year reaches the hottest period.
Hot before or after the summer solstice
The temperature is hot after the summer solstice.
Before the summer solstice, the temperature gradually becomes hot, but it is not very hot. The summer solstice is the beginning of the traditional dog days, which is also the beginning of summer in the northern hemisphere. At this time, the surface receives more solar radiation than the surface anti radiation heat, so the temperature will continue to rise. Therefore, the temperature will continue to rise after the summer solstice.
