What is the truth of the sentence "It's cold until mid-May, I'm shocked"? ?

The arrival of this year's thorny solar terms means that spring has really come, everything is reviving, pear flowers, peach blossoms and rape flowers are in full bloom, and vibrant spring is coming.

However, there is a saying in the countryside that "stinging insects are not frozen, and they are cold until mid-May". How to understand it? On stinging days, it is not cold when it should be cold, not thawed when it should be thawed, and not thawed in advance when it should be thawed, which leads to the increasingly hot weather behind.

This kind of weather will have a great impact on agricultural production and people's health. Literally, if the stinging weather is not cold and insects can't freeze, it will be cold in the future until mid-May. According to the current scientific theory, spring thunder brings everything back to life on the stinking festival, but it will still be cold, cold in early spring and warm at noon.

If the weather temperature is high on the day of Stingray Festival, the warm and humid airflow in the south will collide with the cold airflow in the north, resulting in cloudy, thundering and rainy weather, resulting in cold weather in late spring. "After the sting festival, the hoe will not stop." After the sting festival, spring ploughing has begun, and the field will be a busy scene.

There is also a saying among children in rural areas that "the wind blows the soil 45 times cooler", that is to say, if the north wind blows once, it will be cold and dry, and the temperature will drop. Of course, it is an exaggeration to say that the temperature will drop by 45 degrees, but there will be an adjustment process and the temperature will drop very low. So far, we can predict the weather on March 5, which is the Sting Festival. According to the forecast of the Central Meteorological Observatory, there will be a round of rain in South China from March 3 to 6, and the afternoon of March 5 to 6 will be a dormant festival.

There will be strong convective weather, rain and thunder from Jiangnan to South China, which will well welcome the dormant festival and be conducive to spring ploughing. Before and after the dormant festival, people have a feeling that the temperature is cold in the morning and evening and hot at noon, which is also a normal climate. If it is hot in the morning and evening, there will be a late spring chill, which will have a great impact on the growing rape, wheat, peach blossom and apricot blossom. To sum up, the climate on the day of being stung will greatly affect the future climate. If it gets cold, the temperature will be higher in the first half of the year. If the sting day is warmer, the temperature will be colder in the first half of the year.

"Sting cold, cold for half a year", "Sting north wind, starting from zero in winter", all these show what the weather is like after stinging? It was cold until mid-May.
