Is it normal to have thunder on the beginning of winter? What does it mean that thunder on the beginning of winter is a sign of the coming of spring?
"Winter" means the end, implying that crops should be stored after harvest. In my country, the Beginning of Winter is regarded as the beginning of winter. So, is it normal to have thunder on the beginning of winter? What does it mean that thunder on the beginning of winter is a sign of the coming of spring? The ninth month of the lunar calendar has arrived as promised, bringing a new beginning. Mr. Shui Mo will meet you in the ninth month of the lunar calendar in 2020 to bring you the good and bad fortune of each day!Is it normal to have thunder on the beginning of winter?Meteorological experts say that although thunder in winter is uncommon, it is not considered an "abnormal phenomenon."Because the air is cold and dry in winter under the control of the continental cold air mass, and the solar radiation is relatively weak, the air is not easy to form strong convection, so the probability of thunder and lightning is relatively small. But less does not mean no thunder. Whether there is thunder does not depend on the temperature itself, but on the temperature difference between the upper and lower layers of the air. If the temperature difference between the high altitude and low altitude temperatures in winter is too large, the air will become unstable. The cold air in the high altitude is heavy and will sink, while the warm air in the low altitude is light and will rise, thereby intensifying convection and causing winter thunder. What does it mean that thunder on the beginning of winter is a sign of the coming of spring?From a climatic perspective, after the beginning of winter, the high-altitude westerly jet stream has been fully established in southern Asia. At this time, the strength and eastward movement of the southern branch of the high-altitude westerly wind has a great impact on the precipitation weather in the Jianghuai region.When the Asian region forms a latitudinal circulation and the southern branch of the westerly wind fluctuates strongly, widespread rainy weather will occur. The end of the zonal circulation and the establishment of the meridional circulation are often accompanied by cold waves and a sharp drop in temperature. Around the beginning of winter, precipitation in most parts of my country decreases significantly. The ground in Northeast China is frozen, and agricultural and forestry crops have entered the wintering period; the "three autumns" in the Jianghuai region are coming to an end; Jiangnan is busy planting late winter wheat and transplanting rapeseed; while in South China, it is the best time to plant wheat at the beginning of winter. The quality of water conditions at this time is closely related to the seedling growth and wintering of crops. If there is more precipitation (if there is thunder, it will usually rain), it does not mean that spring is coming. But now it is the Beginning of Winter, so there is a saying that "thunder at the Beginning of Winter means spring is coming." When is the beginning of winter in 2020? This year's Beginning of Winter is at 07:13:46 on November 7, the 22nd day of the ninth lunar month. Last year, the beginning of winter fell on the twelfth day of the tenth lunar month. According to the lunar calendar, this year's Beginning of Winter is nearly twenty days earlier than last year because of the existence of a leap April. Proverbs and meanings about the beginning of winter(1) On the first day of winter, the water becomes three points colder.Meaning: At the beginning of winter, the cold winter has begun. After that, the temperature will gradually drop and the water temperature will gradually become colder. (2) Eat nutritious food at the beginning of winter, and you will be as brave as a tiger in spring. Meaning: At the beginning of winter, with the coming of winter, people begin to take supplements. If they take proper supplements at this time, they will be healthy in the spring of next year. (3) If there is no frost in the beginning of winter, the rice seedlings will freeze to death in spring. Meaning: In some years, the temperature at the beginning of winter is relatively high and no frost appears. The weather will be relatively cold in early spring of the next year, which is very unfavorable for the growth of seedlings. (4) Rain on the beginning of winter will cause potato hooves to rot. Meaning: If there is a lot of rain during the Beginning of Winter, dried sweet potatoes will often rot. (5) If there is no rain on the beginning of winter, the whole winter will be sunny. Meaning: If it does not rain or rains less on the Beginning of Winter, there will be more sunny days in winter. (6) Northeast wind on the beginning of winter, good winter sky.
