Sunstroke is one of the 24 solar terms in the lunar calendar. The sun is located in the Huangjing 120 & deg;. During the summer, Chinese people have the custom of drinking tea, drying ginger, burning incense and drinking mutton soup. Is the folk saying "three dog days" summer heat? How many volts is the great summer of 2018? Come and have a look.
Is it three dog days in summer
The solar term of great summer is in the middle of the three dog days, which is the hottest time of the year. However, great summer and three dog days are two different concepts, so the time of great summer is just in the middle of the three dog days. The term "three volts" refers to the first, the middle and the last, about the period from mid July to mid August. After the summer solstice, although the day is shorter and the night is longer, the day is still longer than the night, the heat absorbed by the ground is still more than the heat emitted every day, and the temperature near the ground is higher day by day. During the three volt period, the heat absorbed by the ground is almost less than the heat emitted, and the weather is the hottest. In the future, the heat absorbed by the ground will be less than the heat emitted from the ground, and the temperature will slowly drop. Therefore, the hottest time of the year generally occurs in the summer solstice.
The solar term of great heat is the hottest solar term of the year. The ancient book "twenty four solar terms" says: "great heat is the extreme heat.". This is enough to show the heat of the solar term. The reason why it is extremely hot in the "great summer" period is that since the beginning of summer, the heat absorbed from the sun during the day on the ground is more than the heat dissipated at night. The heat is continuously accumulated. During the great summer, the accumulated heat reaches the peak, so the great summer is the hottest.
How many volts is the summer in 2018
The summer of 2018 is July 23, which is the time to get rid of clothes.
Early lodging time in 2018: July 17-26, 2018, 10 days
Medium voltage time in 2018: July 27, 2018 - August 15, 2018, medium voltage, 20 days
Last fall of 2018: August 16-25, 2018, last fall, 10 days
The specific date of the three volts is determined by the date of the solar term and the date of the ganzhiji. According to the traditional calculation method of our country, the third and fourth day after the summer solstice is the start date of the first and second ambush respectively, and the first day after the beginning of autumn is the first day of the third ambush.
Summer heat is the hottest period of the year. So there is a saying in the great heat: "it's hard to be in the great heat, and you can't stop knowing.". We should seize the opportunity to fight for both, and prevent heatstroke is the most important thing. From the summer solstice, the surface absorbs heat and the temperature rises continuously. When the summer heat comes, the temperature just rises to the maximum.
