What do snow and thunder mean? What are the signs of snow and thunder?

1, snow and thunder are ominous, and there will be natural disasters, such as drought, rainy days and natural disasters. It snowed and thundered in the first month, which the old ancients thought was an unlucky omen. The ancient poem "Shang Xie" wrote: "In winter, Lei Zhen is rainy and snowy, and in summer, heaven and earth are in harmony, but dare to break with you!" It is considered an impossible natural phenomenon to compare thunder in winter with snow in summer.

2. Thunder in winter, commonly known as "thunder in winter" or "thunder in winter". The weather of "thunder and winter" in winter is not common, but it does exist. However, due to the underdevelopment of ancient science and technology, people think that thunder in winter is an ominous sign. The reversal of day and night and the disorder of the four seasons were ominous in ancient times. In winter, ten cowsheds are empty. In the eyes of the ancients, winter is the season when everything hides. If it thunders in winter, it is called "disturbing the sun". In winter, the sun of heaven and earth should be hidden. From an astronomical point of view, there should be no thunder in winter. If it thunders in winter, it means that heaven and earth can't hide the spirit of the sun, and animals will definitely suffer.

The weather sign of snow and thunder is that a few days before the incident, the local temperature is often above 0 degrees and the humidity is high. On the day of the incident, there was strong cold air affecting the local area. At that time, the strong cold air and the near ground were relatively warm and wet. When the air contacts, the warm and humid air with light weight rises violently, which leads to the instability of stratification and the formation of thunderstorm clouds. The temperature of thunderstorm clouds generated by the lifting is below 0 degrees, so there will be weather phenomena of snow and thunder.
