As the old saying goes, it snows and thunders in winter.

It will snow and thunder in winter. The old ancients said, "It snows in winter, and the grave will be built next year.".

This meaning is also obvious. It means that when it snows in winter and January, if it thunders, more people will die next year, which reminds us that extreme weather will generally bring all kinds of natural disasters, so we must make preparations in advance.

When thunder is heard in winter, even if it snows, it is because the cold and warm air meet fiercely, and the warm and humid air flow rises rapidly to form vertical convection, which will form thunderstorm clouds, resulting in "thunderstorm and snow". This phenomenon is very rare in winter, because the low-level and ground temperature itself is very low in winter, and there is not much chance for convection to be strong enough to produce lightning.

Matters needing attention when it snows in winter:

1, antiskid

Avoid floating ice and stagnant water on the road, wear deep-soled non-slip shoes and walk slowly.

2. Fall prevention

Lift your feet high and tread slowly to reduce the forward friction between the sole and the ground and reduce the possibility of falling. Reduce electric cars and bicycles and choose to walk or public transportation. Be careful when going up and down stairs or steps, and grasp handrails or other fixing devices.

Step 3 prevent smashing

Trees, billboards, etc. Stay away from the snow, when the snowfall is heavy, trees, billboards, etc. It often collapses due to too much snow and is easy to get hurt. Stay away from branches, cables and eaves with ice. In rainy and snowy weather, eaves and branches are easily covered with ice, which is easy to break and slide, hurting pedestrians.

4. Anti-collision

Rain and snow covered many "traps" on the road, such as potholes, manhole covers and building materials. Go out and choose a place with footprints or ruts.
