Why does the temperature usually rise during snowfall?
Answers:
falling snowflakes have a temperature lower than the ambient air (in the upper layers of the atmosphere it is always colder than in the lower ones), therefore, on them, as on crystallization centers, the moisture always present in the air crystallizes, releasing the latent energy of crystallization, which increases the air temperature. A similar phenomenon (only related to condensation) is used to preserve gardens during spring frosts. in spring, with a sharp drop in temperature, water vapor in the air becomes saturated, but its condensation is difficult, because there are few condensation centers (there is little dust in the air in spring). smoky fires are made in the gardens, smoke particles are excellent centers of condensation, moisture condenses on them, the latent energy of condensation is released and the air is heated a few degrees, but this is enough to save the trees. while the air is heated only where there is smoke. it is precisely because of the abundance of centers of condensation and crystallization in cities that it is always warmer than outside the city.

There is a well-established opinion that during the snowfall it becomes warmer. In childhood, this effect was explained to us like this: snowflakes are so light and smooth that they reflect the light of the even dim winter sun, and this light warms everything around. But is it?
Winter has returned to Moscow this week: it started to snow and it got really cold. In our minds, snowfalls are strongly associated with winter and frost. However, you probably noticed more than once that with the appearance of snow in the city it becomes warmer. How is it in reality? Does snow come with cold or with heat? We asked colleagues from Schrödinger's Cat magazine to help figure it out.
To begin with, we note that everything happens like this: snow falls when it gets warmer. That is, the causal relationship of these phenomena is inverse. This, of course, does not mean at all that a snowstorm can cover us in the summer (although this also sometimes happens), because snowflakes are frozen water, and it freezes only at temperatures below zero. Most often, snowfalls attack us in winter, when cyclones come and warm atmospheric front. We talk about these guests and the quirks of nature associated with them in order.
Where does the snow fall from
Precipitation - snow, hail or rain - is formed from clouds. The warmer and more humid the air, the more powerful the clouds - this is an axiom. When the winds bring a warm atmospheric front into the city - that is, heated and wet air, which begins to creep into the cold - there are more clouds, and snow falls. And along with it, the warm front warms up our city. And here it does not necessarily come to a thaw, however, frosts, as a rule, subside. This is the main mechanism of winter warming.
Cloud Blanket
Clouds that generate snowfall, up to two to four kilometers thick, retain heat on the ground, like a duvet. The heated Earth always radiates long-wave radiation - in other words, heat. In anticyclone conditions, when massive clouds fly far away, there is a big difference between cold temperature air and the temperature of the heated Earth - and then it radiates its heat irrevocably. But when a cyclone comes (cloudy weather with precipitation), the warming terrestrial radiation is reflected from the clouds and returns to the Earth's surface in the form of powerful oncoming radiation. So, the air temperature remains positive.
An extra dose of heat
There is another point that affects the change in temperature in the positive direction. When clouds form, water vapor condenses. Remember the term from the school physics course - "exothermic process"? So here in the clouds are coming it's him.
For these reasons, snowfall and warming often come together. But in general, nature is a tricky thing, and sometimes it surprises us with strange behavior. For example, in Moscow, from January 31 to February 1, an anomalous warm weather with rains. And then with a cold front came powerful snowfalls and frosts. So, nature behaves in the best traditions of dualism - snow can come both with cooling and with warming.
