Why does it thunder in December?

1, a rural proverb: when it thunders in the twelfth month, the sword soldiers see ten cowsheds and nine empty ones; Thunder in the twelfth lunar month is rare.

2. It is true that it will thunder in the twelfth month of winter, and it has little to do with the encounter between soldiers and swords. Thundering in winter is the appearance of extreme weather. In winter, when the warm and humid air in a certain area gets warmer, there will be strong cold air going south, causing the cold and humid air to meet. Lighter warm and humid air will rise rapidly due to the influence of airflow, while heavier cold air will fall rapidly, which will directly lead to the instability of atmospheric structure.

3. This extreme thunderstorm and thunderstorm weather will cause a cold wave with extremely low temperature, and there will be a lot of precipitation and snowfall. Bad weather will have a very serious impact on the crops and livestock we feed. In cold weather, some cows will be frostbitten and freeze to death. In addition, this kind of weather will lead to the reduction of farmland production in the coming year, the lack of food, and the lack of food for the villagers, which will also lead to difficulties in farming.

4. Thundering in the twelfth month is indeed an extremely bad weather, and its influence is also very great. This situation will do harm to agriculture, life and other industries, such as freezing rain, blizzard and other bad weather, which is disastrous. With the change of climate in recent years, there are more and more warm winters, winter is no longer cold, and there is much less rain and snow than in the past, but it thunders in winter.
