1. What effect does snowfall have on people's lives? Every winter, many people look forward to snow, because it is a very beautiful sight. If you can wake up after a sleep and see a snowy scene, many people will feel better. Snowfall can not only bring people a very good visual experience, but also purify the pollutants in the air, so that these pollutants fall to the ground with snowfall and the air becomes fresh. In addition, snowfall also means that the weather will be colder, because snowfall must be in the air.

Second, what conditions need to be met for snowfall? If it is going to snow in the sky, certain conditions must be met. First, a large amount of water vapor is gathered in the atmosphere, and the temperature is relatively low, so that water droplets in the atmosphere can condense into snow. When the water droplets in the atmosphere keep gathering and the clouds can't bear it, there will be snowfall, and the pollutants in the air will fall with the snowfall. At this time, it is a complete snowfall process, so the phenomenon of snowfall will only appear in the coldest winter every year, and it is also the most common phenomenon for many people in a year.

Is it cold when it snows? Because snowfall is a weather phenomenon that only occurs when the weather is cold, many people think that it is the coldest time of the year. In fact, this is a wrong idea, because when it snows, the snow falls to the ground and melts, so it must be absorbed. The heat in the air can only be melted, and the heat in the air will become extremely cold after being absorbed, so it is coldest when the snow melts, so we often say that many places will freeze after the snow stops, and people often dare not extend their frozen hands. This is because snow must absorb heat to melt, so it is better when it snows. After the snow stops, you must pay attention to cold and warmth to avoid frostbite.
