How Snow Forms

Snow has become the symbol of winter for most countries around the world that have four season a year. It is embodying the season’s quiet and peaceful aura while more entertaining piles rather than rain or sleet.

Snow happens when there is a warm, moist air rise from the Earth’s surface into the sky, where there it forms a cloud. Then it cause the two air masses collide—forcing the colder air beneath the warmer one. Then the rising water vapor eventually cools so much it converts back to a liquid. The water droplets resulted from that creates a clouds. But the clouds need something to condense onto, like water condense outside the glass. Long-range winds bring all kinds of microscopic debris in the sky that mainly from dust, dirt and salt. The components give the cloud droplets something to hold onto.

This process reach its peak when storm clouds tend to grow up and become colder in the sky. Most of clouds that still in the form of liquid eventually begin freezing once the temperature drop less than 14 degrees Fahrenheit. Then individual droplets of the cloud solidify on by one turn into ice particles, that later may attract other water vapor and droplets toward their surface. This leads to small but fast-growing ‘snow crystals,’ that later fall when they are heavy enough.

This how the snow is formed.
