Why is there frequent hail in spring?

Because spring is one of the seasons with great temperature fluctuation, and the formation of hail is related to many factors such as temperature, humidity and airflow. The following are some reasons that may lead to frequent hail in spring:

Stormy weather: Heavy rain and thunder and lightning often occur in spring, forming a strong vertical airflow, which makes it easier for potential hail clouds to rise into the upper atmosphere and form hail in it.

Large temperature difference: the temperature changes greatly in spring, and the temperature difference between morning and evening is also obvious. In warm days, the air rises rapidly, resulting in strong convective movement, thus increasing the probability of hail formation.

Unstable air flow: alternating spring monsoon and strong cold air intrusion will lead to unstable air flow. When cold air sinks rapidly, it will encounter relatively warm water vapor and form a strong updraft, which is beneficial to the formation of hail.

In short, the factors such as temperature, humidity and airflow in spring are complex and diverse, and the changes of these factors can affect the formation of hail. Although hail may occur every season, it may occur more frequently in spring due to the above reasons.
