SUMMARY
The discussion centers on the phenomenon of hail rain, which occurs when water and ice crystals fall simultaneously from the atmosphere, indicating the triple point of water. This state allows H2O to exist as gas, liquid, and solid concurrently, with gravitational forces causing the heavier forms, liquid and solid, to descend. The conversation also clarifies that for snow to form, the entire atmospheric column must remain below freezing, preventing melting during descent. Hail specifically forms when liquid water passes through sub-freezing temperatures, resulting in ice chunks rather than ice crystals.
