1, we should realize that the purpose of school closure in snowy days is to ensure the safety of students. On snowy days, the roads are slippery and it is difficult to guarantee driving safety. Students may encounter the risk of traffic accidents while going to and from school. In addition, cold weather may also lead to students' health problems such as colds and illness.
2. We should see the possible negative effects of suspension of classes in snowy days. Long-term suspension of classes will affect students' learning progress and lead them to fall behind. At the same time, parents also need to adjust their work and life arrangements and take care of their children at home. This is a burden on the family and society.
We should also see that the development of modern science and technology makes it possible to solve this problem. Through online teaching and distance education, students can continue their studies at home without being affected by the weather. This not only ensures the safety of students, but also avoids delaying the learning progress. Of course, this requires the joint efforts of schools, teachers and parents to create a good learning environment for students.
Snow condition
1. Temperature is an important condition for snow. When the temperature drops below 0℃, the water vapor in the air will condense into ice crystals, which will collide and combine in the air to form snowflakes. So low temperature is the basic condition for snow. Generally speaking, when the temperature is between -5℃ and-10℃, snowflakes are more likely to form and fall.
2. Humidity is also a key factor affecting snowfall. Humidity refers to the content of water in the air, usually expressed by relative humidity. When the moisture content in the air is high, water vapor is more likely to condense into ice crystals, thus promoting the formation of snowflakes. Therefore, areas with high humidity are more prone to snowfall.
3. The stability of the atmosphere will also affect the possibility of snow. When there is a strong updraft in the atmosphere, snowflakes may be dispersed by the airflow during the ascent and cannot form larger snowflakes. On the contrary, under stable atmospheric conditions, snowflakes are more likely to form and fall to the ground.
