Thunder is generally more frequent in summer and autumn, and there will be winter and spring seasons, but there are few, especially in winter, there is almost no thunder weather. Thunder requires two major conditions, one is sufficient water vapor, and the other is intense convection. In this way, the thunder in winter becomes especially embarrassing. Why is it generally not thunder when it snows?

Thunder requires two major conditions, one is sufficient water vapor, and the other is intense convection. These two conditions are very abundant in the summer. Everyone should know about the condition of water vapor. The sea breeze and water vapor blown in summer is sufficient. What is the meaning of strong convection? Strong convection refers to the intense vertical movement of the air, and generally when the heat is sufficient, the air will show significant movement due to the updraft. In the summer, the ground is hot enough, the air will rise continuously when heated, and the pre-cooling will condense into cold water droplets in the granules. When the speed of this rising pre-condensation is accelerated, the friction will collide and thunder. This is the phenomenon of thunder in strong convective weather.

During the winter illumination period in China, the ground is rarely heated, and the airflow rises slowly. Especially the temperature difference between the ground and the sky is not very large. Generally, the water vapor rises to form ice crystals and accumulates into snowflakes, and the positive and negative charges are frozen. How do you collide with lightning? However, if the winter is warmer, the cold air is stronger, and suddenly the warm and humid airflow rises southward to produce a strong convective weather. Sometimes even if there is snowfall, if the cold air meets the warm and humid air, lightning may occur.
