65438+ Abnormal thunder and heavy rain in February.

The normal year is 65438+February, and winter has entered. After winter, the low-level air is dry and cold, which is not conducive to the formation of updraft and thunderstorm weather. The thunder and lightning in 65438+February means that the temperature has been obviously high since winter, which belongs to climate anomaly.

thunder

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 sometimes when the temperature is high in winter, it will form thunderstorm clouds, leading to lightning and rain and snow.

Convection is particularly strong, and it can also form hail, which will produce the weather phenomenon of "thunder in winter". Since the middle of 5438+ 10, the warm and humid air flow has been extremely strong, and the temperature is obviously high. On June 5438+04, the highest temperature reached 22. 1℃, the highest in the same period in history. On June 5438+07, the strong cold air in the north went south and the two met. It not only snowed, but also thundered.

Knowing these reasons, it is not surprising that it thunders in winter. Lightning and thunder are common weather phenomena in summer, while it usually snows in winter. These are two completely different weather phenomena. However, as long as the weather in a certain place has the conditions of snow and thunder at the same time, these two completely different weather phenomena can appear at the same time.
