Introduction: "Whether it's hot or not, it depends on the eighth day of April", tomorrow on the eighth day of April, will it be very hot during the dog days this year?
Time flies so fast, the beginning of the summer solar term has passed half of the solar term, and it is about to enter the next solar term. As soon as Xiaoman arrived, the weather became even hotter, and at the same time, thunderstorms increased.
According to the forecast of the Climate Center, April 2024 was warmer than usual. Specifically, the national average temperature is 13.1°C, 1.7°C higher than the average for the same period of the year, and the highest for the same period since 1961. Among them, most of the central and eastern parts are 2~4 °C higher. The climate forecast of Henan Province also shows that most of the province is 0~1°C higher.
It's just summer, and it's already so hot. So, will it be hotter during dog days this year?
As the old saying goes, "whether it's hot or not, it depends on the eighth day of April", what does it mean? What is the eighth day of April? Is it hot during the dog days this year? Let's take a closer look!
The eighth day of the fourth lunar month is the traditional Buddhist festival "Buddha Bathing Festival", also called, "Buddha's Birthday", "Bathing Buddha", "Buddha Irrigation". According to legend, when Shakyamuni was born on the eighth day of the fourth lunar month, there were 9 dragons spitting perfume and bathing in the Buddha's body. Accordingly, on the Buddha's birthday, Buddhists hold a Buddha bathing event.
Therefore, the weather conditions on this day are also of more concern. Let's take a look at what the agricultural proverbs left by our ancestors say:
1. Eight big blisters in early April, like a fire cellar in dog days
This agricultural proverb means that if there is more rain on the eighth day of the fourth lunar month, it indicates that the dog days of the year will be very hot.
2. On the eighth day of April, it rained, and the fish died on the shore
This agricultural proverb is not difficult to understand, to the effect that if there is rain on the eighth day of April, it is a sign that there may be a drought this summer, the water level in the fish ponds will drop, and the fish will die of thirst due to lack of water. Of course, this agricultural proverb is an exaggeration, meaning that the summer is hot and dry.
3. On April 8, the rain dropped, and the clothes and hats hung on the wall
The meaning of this agricultural proverb is that if it rains on the eighth day of April, there is a good chance of dry weather for the rest of the year. In this way, the peasants' robes and hats were useless and could only be hung on the walls.
Fourth, the eighth day of the first month of April is cold, and the sauna is steamed in dog days
This agricultural proverb means that if the weather is cold on the eighth day of the fourth lunar month, it indicates that the dog days of the year will be relatively hot.
So, what is the weather like on the eighth day of April?
Judging from the weather forecast for May 15, 2024 (the eighth day of the fourth lunar month), there will be a wave of strong rainfall in Jiangnan and South China in mainland China. Among them, Jiangnan, South China and Guizhou will once again have a heavy rainfall process, accompanied by short-term heavy precipitation, thunderstorms, strong winds or hail and other strong convective weather.
Specifically, heavy rain or torrential rain may occur in central and southern Zhejiang, northwest Fujian, central Jiangxi, southern Hunan, Guangxi, central and western Guangdong, southeastern Yunnan and western Chongqing, northern and southeastern Guizhou, among which central Jiangxi, southern Hunan, and northeast Guangxi may also have heavy rain weather processes.
Compared with the rainy weather in the south, the northern region is constantly experiencing high temperatures. Judging from the forecast released by the Central Meteorological Observatory, in the next 10 days, the daily maximum temperature in the Xinjiang Basin of the mainland will reach 35~38 degrees for 5-8 days, and the local maximum temperature will reach 39~42 degrees.
During the period of May 17-19, there were 2-3 days of high temperature weather with a daily maximum temperature of 35~37 degrees in the central and western parts of Inner Mongolia, central and southern North China, Huanghuai and Guanzhong of Shaanxi Province on the mainland.
It should be noted that during the period from May 17 to 19, moderate to severe dry and hot wind weather may occur in the wheat producing areas of North China, central and southern China, Huanghuai and Guanzhong of Shaanxi.
The so-called hot and dry air actually refers to the weather with high temperature, low humidity and a certain amount of wind. This kind of weather is not good for the growth of wheat, which will cause a large amount of water evaporation from the wheat plant, so that the water in the wheat body is depleted very quickly.
If the water consumption in wheat is too fast, the photosynthesis of wheat will be hindered, and pigments such as chlorophyll will also be destroyed. Especially during the grain filling period of wheat, if there is a dry and hot wind, the ears of wheat are not conducive to grain filling, and they may dry up early, and the wheat grains will become shriveled up, and the grain weight will also decrease, resulting in a decrease in yield.
In short, on the eighth day of the fourth lunar month, the rainfall in the south of the Yangtze River and southern China in the mainland has a certain intensity, while the northern region is hot and dry, and some areas will have a dry and hot wind weather process. And, according to the agricultural proverb, if it rains on this day, it is a sign that the dog days of the year will be very hot.
