What is the cause of hail formation in Heilongjiang?

The causes of hail formation in Heilongjiang are: the interaction between thermal rise and cold vortex, climate change and weather system.

1, thermal rise and cold vortex: thermal rise and cold vortex in northeast China may be one of the main causes of hail. When hot air meets cold air, it will form an unstable atmosphere, which will condense the water vapor in the cloud into hail.

2. Climate change: Global climate change may also have an impact on this hail event. Climate warming leads to the increase of atmospheric temperature, which increases the chances of convective activity and convective cloud formation, and may increase the frequency and intensity of hail.

3. Interaction of weather systems: The interaction of weather systems is one of the key factors to form hail. There may be multiple weather systems in Heilongjiang, such as cold front, warm front and low pressure system. This interaction will cause the fierce collision and rise of airflow, thus forming hail.
