Is melting snow a weather phenomenon?

Snow melting is not a weather phenomenon, but a physical phenomenon.

Weather phenomenon refers to various natural phenomena in the atmosphere, that is, the comprehensive expression of the spatial distribution of various meteorological elements in the atmosphere (such as temperature, pressure, humidity, wind, clouds, fog, rain, flash, snow, frost, thunder, hail, haze, etc.). ) in an instant.

When snow melts, no new matter is produced, but the state of matter changes, so this is a physical change. Snowflakes are formed by condensation of water vapor in the air. In general, water vapor will condense into water before freezing, but snowflakes are formed directly after condensation of water vapor. The temperature of snowflakes is low. After the snow falls to the ground, due to the high ground temperature, the snow absorbs heat and the temperature of the snow rises, resulting in a physical phenomenon, that is, melting.
