You who enjoy the snow

We should also learn more about snowflakes~

How heavy is a snowflake?

Generally, the diameter of a single snowflake is between 0.2 mm and 6 mm, and the snowflake itself is not heavy, with the total weight of 5,000 to 10,000 snowflakes being only 1 gram. However, when snowfall continues, the snowflakes will continue to gather, and 1 cubic meter of snow is composed of about 6 billion to 8 billion snowflakes, which are heavy enough to crush trees and temporary structures.

How deep is the snow?

Data shows that under normal circumstances, 1 mm of snowfall is equivalent to 8 to 10 mm of snow in the north and 6 to 8 mm of snow in the south, mainly because the water content of snow in the north is lower than that in the south.

The places with the deepest snow in my country are mainly distributed in the eastern part of Northeast China, central and western Xinjiang, and western Tibet. The annual snow accumulation can reach more than 20 cm, and in some places it can reach 50 cm, which is above the knee.

Is the snow heavier in the south than in the north?

In the north, 100 square meters of 8-10 mm snow weighs 100 kilograms, while in the south, the same area of ​​snow weighs 130 kilograms.

This is because snow is divided into dry snow and wet snow. If the temperature of each air layer is always below 0℃ during the snowflakes' descent, they can fall to the ground as snowflakes, forming dry snow ; if the snowflakes pass through a warm layer during the descent, they tend to become moist and melt, forming wet snow . The moisture content of wet snow is relatively high, so the weight of wet snow is relatively heavy for the same volume.

If the snow accumulation on a 100 square meter roof exceeds 40 centimeters, it will bear more than 3-5 tons of pressure, which is really "a lot of pressure"! Therefore, relevant departments or individuals need to deal with snow and ice accumulation in a timely manner during heavy snow or blizzard weather to prevent disaster risks.
