In the year 2024 of the Gregorian calendar, dog days are the hottest time of the year and the hottest 25 days of the year, but the dog days of 2024 are a little special, first of all, the dog days last for a very long time, up to 40 days, and secondly, there is bad news and a good news coming out online.
That's why dog days in 2024 will be so special, and what impact does good and bad news have, let's explore the mysteries of dog days.
Dog days of 2024, two bad news.
The dog days in 2024 are 40 days, and the dog days are divided into three parts: the beginning, the middle, and the end, of which the middle days are the hottest, and the middle days are the core of the dog days, accounting for more than half of the dog days.
And the dog days are in that period, from the end of June to the middle of July, which is the transition period of the climate, so why is the climate so hot, just like the land is dry and people and animals are miserable as written in the "Zizhi Tongjian"?
And there is still a remnant sun like blood, this dark picture, it is indeed painful, so how did people record the climatic phenomena during the middle period thousands of years ago?
That's a folk proverb.
As early as the Tang Dynasty, people have been aware of the horror of the dog days, and at the same time recorded the climatic phenomena of these dog days, and this proverb is: "The first wheat and autumn leaves, the middle of the summer days, the last of the grass ripe, white dew and autumn high fields."
This is the folk proverb left to us by the Tang Dynasty about dog days, which also conveys some of the ancients' understanding of the climate, from the growth of crops, we can see what the temperature of dog days is.
The leaves of the wheat seedlings in spring are very thin, and the water on the leaves alone can make the whole wheat stalk wet, and at the beginning of the year, half of the wheat or wheat seedlings have already yellowed and shiny, which is also the day of the wheat harvest in the middle of the year.
Because at the end of the period, the seedlings begin to mature, and some have even been harvested, and the seedlings at this time begin to enter the mature stage, and the temperature is the highest during the middle period.
The temperature can sometimes reach more than 40 degrees, and the temperature in the eastern part of the country is very high, but the temperature in the middle of the region is also much higher than that of the first place.
A large part of this is due to the fact that the direct sunlight gradually shifts southward during the middle of the day, which brings the hot summer weather to the central region, and the southern rainy season ends just right in the middle of the day.
This makes the weather in the south hotter, more exciting is that the air pressure at this time drops again, coupled with the summer weather in the south, the air is filled with a large amount of water vapor, these water vapor in such hot weather is easy to form large-scale convective clouds, if the water droplets in the clouds increase, it is possible to rain, but during the dog days due to the huge temperature difference, it is conducive to the formation of convective clouds, but the water droplets are difficult to reach the degree of condensation.
Therefore, there is basically no rain on the three volt days, which causes the drought of the air, like the northwest region of the mainland at this time will experience desertification, and the Ejina Banner of Inner Mongolia has the largest mobile desert in the world, which has a lot to do with the dryness of the three volts.
Dog days in 2025, good news.
"The early wheat and autumn leaves, the middle of the summer day, the end of the wheat ripe, the white dew autumn high field."
Some climatic phenomena can be seen in this proverb, and some changes in farming can be implied according to which you can manage the corresponding farming.
Nowadays, people's rhythm of life is no longer the self-sufficient agricultural civilization of ancient times, almost all of them live in the city, so during this time, most of the year is spent in air-conditioned rooms, obviously not as comfortable as in the past when spring planting and autumn harvesting.
Even so, the older generation of people will also prevent some disasters according to this sentence, for example, when it is time to prevent the burning of the shed, and remove the hot items in the shed in advance.
At the same time, you can also check whether the water in the rice field has been dried, and if it is dried, it will be soaked in water in advance, so as to prevent the fish and shrimp in the rice field from dying of heat as much as possible.
But nowadays, people can only sweat against the scorching sun in the sky, and at the same time increase the time for outdoor exercise, which is very bad for the body, resulting in many people's physical problems, such as heat stroke, sunburn, and other problems, so this way of the ancients is still worth referencing.
And there is good news in the dog days of 2025, that is, the temperature will not be as high as this year, like in North China and other places, the middle volt area is much hotter than the eastern region, but if the weather in the middle volt is similar to that in 2023, it is estimated that many people will hang.
So why is it estimated that the temperature in 2025 will not be so high?
According to the forecast of meteorological experts, the dog days in 2025 will only be 30 days, and if 2025 is still dog days, it will be 2/3 of 2024, which will also be very hot.
So it can be predicted that the temperature on dog days in 2025 will not be so high.
However, the temperature in many countries has risen and decreased to varying degrees, but on the whole, it has risen, which has a lot to do with human activities.
The temperature of dog days changes so much, of course, it is due to human beings, and on the other hand, it is also because the overall trend of the earth's temperature is rising, so it will also affect the temperature of dog days in general.
Climate change trends, dog days for the future.
The dog days are an important time node of the year, an important weather background, and the development of dog days today not only affects the growth of crops, but also affects our lives.
Judging from the current development trend, the temperature of dog days is going up with a certain law, so the temperature of dog days is very likely to be very high in the future, so we should strengthen the prevention of dog days.
In fact, in the dog days of hot weather, and now people enter the summer, they will selectively go to the supermarket for night shopping, and some sports enthusiasts will choose to run late at night to fight against the scorching sun during the day, but when doing outdoor sports, the occurrence of heat stroke will greatly increase.
Therefore, in the summer, it is necessary not only to reduce outdoor activities, but also to minimize the number of times you go out, and at the same time, you should drink plenty of water, so as to better withstand the heat.
In addition, in the hot weather, the most important thing is some small details of life, so in the hot summer, it is best not to go out at noon, and do not cook soup and stew.
Cooking soup and stew can easily make people feel hot and can hurt our stomach, so we must pay attention when drinking hot drinks, because drinking hot drinks in summer is actually causing damage to the stomach.
There are many people who think that ice cream is the best food to cool down, but the temperature in summer is very high, and the body is greatly stimulated, and ice cream is a cold food, so it is easy to cause gastrointestinal discomfort.
Therefore, this is also known as "taking chestnuts from the fire", so you must be cautious when buying cooling foods in the summer.
At the same time, in the hot weather, in order to alleviate the discomfort caused by the hot summer, some life hacks are particularly important, and those who can cool down must be learned.
epilogue
Dog days are no longer the dog days of the past, they have become less extreme, but the duration of dog days is getting longer and longer compared to previous years.
The temperature is increasing year by year, and the amount of rain is also decreasing year by year, so we should take responsibility for environmental protection and reduce some of the pollution that can be reduced.
The proverb of the ancients taught us how to adapt to natural phenomena and how to summarize some valuable things from the natural world, so this is the inheritance of the wisdom of the ancients, and we should pass it on.
