In China's thousands of years of agricultural civilization, the ancestors summed up a lot of practical experience through long-term agricultural production practice and understanding of the weather and production relations, which can guide us to agricultural production very well. Today is the twenty-seventh day of the seventh month of the lunar calendar, there is an old saying in the countryside called "cold or not, just look at the twenty-seventh of July", so this winter is not cold?
July 27 has entered the third season of the summer, that is, "Henadan", which means that the autumn harvest crops are about to mature, the autumn harvest crops have entered the final stage of growth, and the weather conditions in the following period directly affect the harvest of crops, so people pay great attention to the weather conditions on July 27. There is an old saying in the countryside called "July 27 fixed drought and flood", the weather changes on July 27 directly affect the next weather changes, naturally determine whether this winter is cold or not, the following I use 3 old sayings to explain.
First, the rain falls on July 27, and the continuous drizzle drizzles until winter
The meaning of this sentence is that if it rains on July 27, then there will be a long period of continuous drizzle, indicating that there will be more rain throughout the autumn.
As the saying goes, "one autumn rain is one cold, ten autumn rains put on cotton". If the rain in the autumn is still very much, it means that the cold air in the north and the warm air in the south continue to meet and merge, and the cold air in the north continues to invade, and the weather will become more and more cold. Secondly, the rain will absorb a lot of heat, each rain will cause a cooling, when about ten autumn rains, people have to wear cotton clothes to protect themselves from the cold. Therefore, if there is a continuous rainy weather in the autumn, then the cold weather will come earlier, so people will feel that the winter is particularly cold.
Note: From this old saying, we can see that it is not a good thing to rain on the 27th of July in the lunar calendar, and it is likely that the rain on this day will indicate that there will be more rain in the future. At this time, the crop is in the late stage of growth, the demand for water is small, if the rainfall is easy to lead to crop "greedy green and late ripening", in addition, more rain means less sunlight, low temperature, which is bound to reduce the photosynthesis of plants, then it is not conducive to the accumulation of crop nutrients, which will lead to crop grain is not full, which will eventually lead to a reduction in food production.
Second, the rain hit July 27, and the old cattle froze to death in winter
The meaning of this sentence is very understandable, that is, if it rains on July 27, then the winter will be unusually cold, and old cattle may be frozen to death. This also indirectly indicates that it rained on the 27th of July in the lunar calendar, indicating that there would be a lot of rain in the future, and the weather would be colder earlier.
Old cattle are large, frost resistance is very strong, if even the old cattle are frozen to death, then it means that the winter is very cold, note, here "frozen to death old cattle" although a little exaggerated, but the image of the winter cold degree, indicating that the winter is very cold.
There is also an old saying in the countryside called "the rain falls at the end of July, and the winter freezes to death", these two sentences are one meaning, which further indicates that if it rains at the end of July, then the winter will be very cold.
Three, July 27 hot baking, 100 days without frost
It has been said above that it will rain on July 27, and then there will be a lot of rain, and the weather will be colder earlier, so what is the omen of the 27 days of july?
As the old saying goes, "July 27 is hot and baked, and there is no frost for 100 days". "Hot baking" indicates that the weather is sunny, while "100 days without frost" indicates that cold days come late, indicating that this winter is a warm winter. This sentence says that the weather is clear on July 27, then the next weather will be hot, and it will not be frosted until almost a hundred days later. Under normal circumstances, it will fall before and after the frost falls at the end of October, and the 100 days will be almost until the end of November, indicating that the cold weather comes late.
There is an old saying that "on the twenty-seventh day of July, the head is dried, and after the autumn, the family celebrates a good harvest." This sunny day indicates that the next weather will continue to be sunny, rainy weather will be less, and cold days will come late, which is a good thing for agricultural production. Crops have plenty of time to grow, the grains will be fuller, and the grain will be bumper. Secondly, on sunny days, the fields and roads will be relatively dry, which is very conducive to farmers' agricultural production.
Summary, July 27 set drought and flood, if it rains on this day, then the next rain will be more, then the winter will be colder; if the weather is sunny on this day, then the next period of time will be less rain, more sunny days, then the winter will be warmer.
China's winter is not cold, to see whether there is a "La Niña" phenomenon, the so-called "La Niña" is the anti-El Niño phenomenon, El Niño is a warm current, will make the Pacific Ocean temperature abnormally warm, and la Niña phenomenon will make the central and eastern Pacific sea water abnormally cold.
Once the La Niña phenomenon appears, China is prone to "cold winter", like the rare low temperature rain, snow and freezing weather that appeared in China in 2008, which is caused by the Pacific La Niña phenomenon.
After the summer this year, the temperature in all parts of China is not too hot, and from the weather forecast of the next 10 days in China, there may be a typhoon generation in the South China Sea and the northwest Pacific, and the rainfall in North China, Northeast China, southern China and other places in the next 10 days will be 30% to 50% more than the same period of the year, and the local part is more than 1 times more, so in the short term, the "autumn tiger" cannot come (the so-called autumn tiger, that is, the weather above 35 ° C after the ambush), this autumn will be cooler.
According to supercomputer analysis, the probability of La Niña in the second half of this year is relatively large. Therefore, this winter is more likely to be a cold winter.
To sum up, "If it is not smooth, just look at the twenty-seventh of July", from the proverb left by the ancestors, today's weather will affect the next weather direction. Now at the end of the seventh month of the lunar calendar, the next 10 days most of our country has rainy weather, combined with the recent "La Niña" phenomenon to analyze, this year is a relatively large probability of cold winter.
