Introduction: "I'm afraid of the rain on the fourth day of April", the fourth day of the first day of April is not ordinary, what are you afraid of when it rains?
Today is May 11 of the Gregorian calendar, the fourth day of the fourth lunar month, although it is not a traditional holiday, but it is an unusual day in folk beliefs. Because, this day is Manjushri's birthday.
Manjushri is the teacher of the Seven Buddhas, the head of the four bodhisattvas, symbolizing goodness and great wisdom, and is the great bodhisattva in Buddhism, representing wisdom. Therefore, friends who have candidates at home may wish to say goodbye and pray for a gold list title!
In addition, the fourth day of the fourth lunar month is usually between the beginning of summer and the small full solar term, and the thunderstorms increase, and the ancients predicted the next rainfall and the drought and flood in the second half of the year through the weather conditions of this day.
For example, there is a saying among the people that "I am afraid of the four rains in early April", what does it mean? What is the sign of rain on a sunny day? Let's take a look at what the agricultural proverb says.
First, the third day of the first month and the fourth rain, it is difficult to have nine sunny days in January
This agricultural proverb means that if it rains on the third and fourth days of the lunar month, it means that there will be more rainy days and fewer sunny days in that month.
There is also a similar agricultural proverb "The fifteenth day of the first month is not good, but there must be few sunny days in this month", which expresses a similar meaning.
There is a certain truth in this agricultural proverb summarized by the ancients, and it is not a blind guess, he predicts it according to the characteristics of "atmospheric rhythm".
For example, the old saying "the clouds cover the moon on the fifteenth day of August, and the snow lights up on the fifteenth day of the first month" is to predict the weather conditions of the Lantern Festival through the weather conditions on the 15th day of August according to the rhythmic relationship of the atmosphere.
In addition, we often say that "the head is covered with rain and the rain is subdued", which also makes use of the characteristics of "atmospheric rhythm". In addition, such as "looking at the second and third days of the first month, and looking down at the fifteenth or sixteenth year", "the cold wind welcomes the heavy snow, and the weather is warm in March and September", etc., all make use of the characteristics of atmospheric rhythm, and there will be corresponding weather conditions every 10 days, 30 days, and 150 days.
In today's parlance, weather is the result of a combination of factors such as air currents, air pressure, temperature, humidity, and so on. If there is rain on the third and fourth days of the new year, it is likely to mean that the humidity in the atmosphere is high, accompanied by a decrease in air pressure. This weather condition tends to persist for a while as changes in humidity and air pressure take a certain amount of time to adjust. During this process, cloudy and rainy weather may occur frequently, resulting in a relatively small number of sunny days throughout the month.
Therefore, this agricultural proverb summarized by the ancients is not a simple inference, but the crystallization of experience summarized through long-term observation.
2. Four rains in the first month of April, forty-five days of storms
This agricultural proverb means that if it rains on the fourth day of the fourth month of April, then there will be more rainy weather in the future, and it will fall intermittently for 45 days. Of course, this is an exaggeration, meaning to express the rain.
In March and April, it was sunny and sunny, and it was so hot that it jumped
The meaning of this agricultural proverb is just the opposite of the previous one, which means that if the fourth day of the fourth lunar month is a sunny day, then it indicates that it will be relatively hot during the dog days of the year.
Why do you say "I'm afraid of the fourth rain in early April"?
This is mainly for agricultural production, because this is the time when the wheat is ripe, the demand for rain is no longer high, and sufficient light and suitable temperature are needed to make the kernels fuller, so as to increase the yield. If there is rainy weather, the temperature will drop, which is not conducive to the ripening of crops.
In addition, rainy weather will cause water accumulation conditions, and high temperature and humidity will easily lead to crop diseases and pests, which will affect yield. Bad weather can even cause crops to lodging and root rot. Therefore, farmers are more worried about the rainy weather at this time, so there is a saying that "they are afraid of the rain on the fourth day of April".
So, what's the weather like next?
Everyone knows the weather on May 10, the Central Meteorological Observatory has hung the double warning signal of heavy rain + strong convection, and there are more places where it rains, with a certain extreme line.
For example, on May 10, Henan did usher in strong convective weather, scattered showers, thundershowers, and strong convective weather such as thunderstorms and strong winds of magnitude 8 to 10, short-term heavy precipitation and hail in some places.
According to the latest weather forecast, the rainfall in the next two days will be mainly concentrated in southern China, southeastern Jiangnan, Yunnan, Taiwan Island and other places. Heavy to heavy rain is expected in these areas, especially in parts of Guangdong, Guangxi, Fujian and other places.
At the same time, the above-mentioned areas may also be accompanied by strong convective weather such as short-term heavy precipitation and local thunderstorms and strong winds. Among them, the areas with relatively heavy rainfall are from the southeast of Jiangnan to the central and eastern parts of South China, the central and eastern parts of Guangdong and the coastal areas and the southern Fujian area.
