What is the difference between sleet and snow? Which is colder?

In so many weather phenomena, sleet is quite common, and there is another kind of snow. Although there will be some similarities between the two, there will still be great differences in comparison. Come and have a look with me. What is the difference between sleet and snow?

When small ice crystals grow to overcome the resistance and buoyancy of air, when the air near the ground is above 0℃, but the air layer is not thick and the temperature is not very high, the snow falls to the ground before it can completely melt. This is the so-called "wet snow" or "both rain and snow". This phenomenon is called "sleet" in meteorology

The nature of meteorology is different: in meteorology, precipitation is divided into rainfall and snowfall. Snow is completely snow, which is completely different from rainfall; Sleet is a transitional property from rainfall to snowfall, and it also has some meteorological and geophysical characteristics of rainfall.

Weather (temperature) conditions are different: when it snows, the ground temperature must be lower than 3℃, otherwise it will be rain or sleet. Only when the ground temperature is lower than 3℃, the ice cubes formed in the sky will not melt into liquid water; When sleet comes, the ground temperature is usually 3℃ or between 3℃ and 4℃. Under this temperature condition, the ice cubes at high altitude will not completely melt into liquid water, but have melted a part when they fall near the ground, and then form an ice-water mixture.

The physical properties and physical forms of precipitation are different: when it snows, it is completely solid water (ice), and its temperature is 0℃ lower than the freezing point of water; What the sleet drops is the mixture of ice and water, that is, water with the transition property from liquid water to solid water, and the temperature is around freezing point, that is, slightly higher or lower than 0℃.

Today, let's briefly introduce sleet. If you want to know more about sleet, please continue to pay attention to our website. I hope today's content can help you.
