What is the weather when it thunders after the light snow solar terms?

The slight cold is the 23rd of the 24 solar terms, and the slight cold and thunder indicate that the weather will be bad. In fact, lightning is a discharge phenomenon in thunderstorm clouds. Thunderstorm clouds generally have two conditions, sufficient water vapor and strong convection. In winter, because the air is cold and dry, the solar radiation is weak, and convection is not easy to form in the air, so lightning is rare.

But in winter, sometimes the temperature is high and the warm and humid air flow is strong. When there is occasional strong cold air going south in the north, the warm and humid air is forced to rise, and the convection intensifies, forming thunderstorm clouds, producing lightning, rain and snow weather, which is particularly strong, and can also form hail, which will produce the weather phenomenon of "thunder in winter". Thundering in winter means that the air humidity is high and it is easy to form rain and snow, so there is a saying that it thunders and snows in winter.

Extended data:

The light snow thundered after the solar terms, indicating the need to cope with the cold. People first think of adding clothes, but they often wear thick clothes and ignore the cold protection of their heads, and even regard hats as irrelevant things. In fact, the human head is closely related to the thermal balance of the whole body. There is a folk saying that "wearing a cotton-padded hat in winter is like wearing a cotton-padded jacket".

In cold conditions, if you just wear warm clothes instead of a hat, the heat of your body will quickly dissipate from your head. The proportion of this heat loss is quite large. Wearing a hat outdoors in winter, even a thin hat, has a very obvious cold-proof effect.
