This morning, suddenlyThunderWoke me up. WinterThunderThis anomaly has attracted widespread attention and has given rise to many proverbs and sayings among the people. Among them, the most well-known is "thunder and freezing, and graves are piled up". This old folk proverb conveys winterThunderThe ominous omen that heralds winterWeatherabnormal, which can lead to the death of more elderly and sick people. Well, winterThunderWhat are the signs?How much scientific evidence is there to support this claim?Next, let's ** together.
The phrase "thunder strikes in winter, graves are piled up" is intended to express winterThunderA bad omen. WinterThunderSeen as an anomaly, it predicts the follow-upWeatheris often accompanied by extremes such as heavy rain and snow, and cold temperaturesWeatherVariation. According to folk tradition, winterThunderwill lead to more deaths, increasing the number of graves.
Every winter,Thundersounded, and the folk legend of "thunder strikes winter, graves are piled up" is remembered by people. This proverb has its origins in military farmingSocialAt that time, people's observation and interpretation of natural phenomena deeply affected their lives. The ancients believed that winterThunderis unusualWeatherphenomenon, meaning nextWeatherIt will be abnormal, especially with frequent rain and snow and sudden drop in temperature. For the poor people at that time, winter was already an unbearable season, and the cold and wet climate exacerbated their living difficulties. Therefore, if the winterWeatherIf it is unusually cold, then more old people and sick people will die as a result, thus forming more graves. This once again verifies the meaning of the ancients saying that "thunder strikes winter, and graves are piled up".
Turning back the curtain of memories, it seems that you can feel the cold of midwinter. A thin layer of frost condensed on the cold window panes, and snow was falling outsideCold windsCold. SuchWeatherIt is undoubtedly fatal for the frail elderly and sick. And whenThunderSuddenly, the silence of the winter night was broken, and people began to speculate that this was anything but unusual. They have deliberately flipped through the proverbs, looking for the winterThunderExplanation. "Thunder strikes winter, graves are piled up", behind this seemingly simple sentence, there are people in the futureWeatherand concern for the safety of life.
WinterThunderThe phenomenon is not uncommon in nature. Although compared to the spring and summer seasons, winterThunderis less frequent, but not impossible. Thunder and lightning activity is frequent in summer, mainly due to factors such as high ground temperature, strong air movement and high humidity. In autumn, when the temperature drops and the air becomes drier, lightning decreases. However, when strongCold airWhen encountering an unusually strong warm and humid air current, it can still cause violent gas convection, which can lead to the occurrence of lightning phenomena. In addition, it can also form when warm, moist air currents are very strong and convection is unusually strongHail。The phenomenon of "thunder and freezing" that has appeared in the northern region in recent days is precisely due to the strong forceCold airThe effects are triggered by the intensification of convection of air currents.
In the cold of winter, the air that should be dry and cold suddenly becomes moist, as if with a hint of mistCold windsQuietly blowing. There seemed to be a quiet and peaceful atmosphere in the air. Suddenly, a piercingThunderLike lightning piercing the sky, people are awakened from silence. Since ancient times,ThunderIt is endowed with mysterious and terrifying imagery, people forThunderThe appearance is always with uneasiness and worry. However, science explains this phenomenon with rigor and rationality. WinterThunderIt's not uncommon, it's just less frequent than spring and summer. This is the result of the weakening of convective intensity due to dry air and inactive air currents in winter. However, when strongCold airWhen encountering an unusually strong warm and humid air current, the confrontation between the two air currents will trigger a violent confrontationAir convection, resulting in the phenomenon of lightning. This phenomenon, while uncommon, is not strange or abnormal.
In general, winterThunderThe phenomenon is not abnormal or unusual. Although compared to summer, winterThunder, but it is still a manifestation of nature. Folk proverbs and sayings often portray this phenomenon as a bad omen in an exaggerated and worrying way, but in reality, it is only a natural phenomenon and has no special ominous significance. Scientific explanations suggest that winterThunderThe reason for the occurrence is strongCold airCollision with warm and humid air currentsAir convection。Therefore, people are facing the winter seasonThunderBe rational and calm, and pay more attentionWeatherForecasts in order to take appropriate precautions. At the same time, the increase in thunder and lightning activity in winter also means that the temperature is lower and the snowfall is worse, so people should take timely measures to protect themselves from the cold and keep warm to ensure safe travel.
