Is the summer solstice in 2019 the hottest time? Is it easy to get heatstroke on the summer solstice?
Introduction: In our country’s traditional culture, solar terms are one of the important traditional cultures. So is the summer solstice in 2019 the hottest time? Is it easy to get heatstroke on the summer solstice? Pomegranate flowers are in full bloom in May of the lunar calendar. Han Yu has a poem that says "The pomegranate flowers in May are bright to the eyes". If you want to know more about May of the lunar calendar in 2019, come to Mr. Shui Mo!Is the summer solstice in 2019 the hottest time?The summer solstice in 2019 is not the hottest time, so it is not the beginning of the dog days yet. The dog days are the hottest time!The main reason is the effect of the atmosphere. The atmosphere has a strong thermal insulation effect. If there is no atmosphere, after the summer solstice, the daylight hours in the Northern Hemisphere will shorten day by day, the heat received will become less and less, and the heat lost will become more and more, and the temperature will drop day by day. The heat we usually feel is not actually caused by the sun, but is reflected from the ground to the atmosphere because the earth is wrapped in a dense atmosphere. Near the ground is our direct heat source. Although the ground absorbs a lot of heat during the summer solstice, it takes about a month for it to be completely released. On the summer solstice, the Northern Hemisphere does receive the most heat from the sun, but in the dozens of days after the summer solstice, although the sun's position is not the highest, it is still quite high; the daylight is not the longest, but it is still quite long. The amount of heat received each day exceeds the amount of heat lost, so the average daily temperature continues to rise, reaching its highest point during the dog days of summer. The earth is wrapped in a dense atmosphere. Sunlight directly penetrates the atmosphere to heat the ground. The ground then transfers heat to the air through infrared radiation, air convection and water evaporation. As for the heat from the sun, it is possible for it to enter the atmosphere unimpeded, but it is very slow and difficult for it to exit, which is a bit like "easy in, difficult out", thus creating a thermal insulation effect. This prevents the surface temperature from being too high, and at night, this heat prevents the surface temperature from being too low. The average daily temperature then depends not so much on how much heat we get from the sun as on the daily difference between how much heat we get and how much we lose. Is it easy to get heatstroke during the summer solstice?Generally speaking, no, because it is not the dog days of summer yet.However, the temperature is gradually rising at this time, so some outdoor workers still need to pay attention to heatstroke prevention and cooling in advance! The summer solstice was also called "Summer Festival" or "Summer Solstice Festival" in ancient times. In ancient times, on the summer solstice, people offered sacrifices to gods and prayed for the elimination of disasters and a good harvest. "The Book of Zhou: Spring Officials" states: "When the summer solstice comes, bring ghosts and goblins to the local area." In the Zhou Dynasty, offering sacrifices to gods at the summer solstice was meant to eliminate epidemics, famines, and deaths from starvation. After the summer solstice, the dog days of summer begin. During this time, the weather is hot, people lose appetite, and become thinner. Therefore, the summer after the summer solstice is also called "bitter summer." The dog days after the summer solstice are divided into the first, middle and last dog days. The dog days are the hottest period of the year, and it is easy to get heatstroke and get sick, so special attention should be paid to heatstroke prevention at this time. When arranging outdoor work and sports, avoid the scorching sun, especially around 2 pm, when the sun's ultraviolet rays are the strongest. Try to avoid going out. In addition, you should have a certain length of lunch break at noon. The new year of 2019 has already begun. Will you be able to find your soulmate this year? Is your love luck good?
