Why does it get cold after it snows?

In the past two days, the 24 solar terms have been snowing heavily, and the weather suddenly dropped, -4, -8,-10 ... today it actually dropped to 14 degrees! ! !

When the mother who was knitting heard the weather forecast, she immediately took out some thick clothes from the cupboard, including socks, scarves and gloves ... the quilt was added several layers. "ah! As for such exaggeration? " I said. "Of course, you don't know how cold it is!" Mom contradicted me.

The next day, it was time to go to school. When my mother saw me off, it was against the wind, and I rode slowly. At this time, I began to observe pedestrians on the road: someone put his hand into his sleeve; Some people stamp their feet straight; Some people are still rubbing their hands. Although they were wearing cotton-padded clothes and thick gloves, they were still shivering with cold. At this time, I also feel very cold: my face is cold and my hands and feet are stiff. At school, students didn't put their schoolbags, so they ran to the radiator and put their hands on it. Their noses and ears are purple and red with cold. At this time, they also shouted: "It's freezing! Frozen to death! "

After class, the students began to play games, and the male students got together and played gyro on the frozen ice, and hot air came out from time to time. Just as we were having fun, we rang the bell for class. ...

As soon as they entered the classroom, the students shrank their heads and opened their mouths. After a while, the students didn't catch a cold, so they started their classes again.

Finally looking forward to the day of school, the students rushed out of the school. I am no exception. When I got home, I went straight to the radiator.

Winter, winter, I didn't expect you to play so wild. I really hate you! It doesn't matter, this matter is known by the weather mother, see how she cleans up you!
