【Sea and River Safety Discussion】In the northern regions, what should be done about snow accumulation on rooftops during winter?

Precipitation is the value measured by meteorological observers, in millimeters, after converting the snow collected over 12 or 24 hours into water using standard containers. Snow depth is the thickness of the snow that we usually see, which is the vertical distance from the surface of the snow to the ground, measured in millimeters. Generally, the amount of snow that can accumulate per millimeter of snowfall depends on factors such as ground temperature and the water content in the snow. If the ground temperature is high, the snow will melt as soon as it touches the ground, and no snow accumulation will occur ； If the snow contains a high amount of water, it will be relatively thin; whereas if the water content is low, the depth of the snow cover will be relatively greater. Data shows that under normal conditions, 1 millimeter of precipitation is equivalent to 8 to 10 millimeters of snow in the north, and 6 to 8 millimeters of snow in the south, mainly because the water content of snow is lower in the north than in the south.

The canopy of the premium project was crushed

Regarding the risks posed by snow, many people have no experience with it; unlike heavy rain, people are not as vigilant in terms of prevention.

All of these seem to be done arbitrarily. Different areas should consider different construction methods or specific preventive measures. Similar to some canopies in the south, a simple canopy can provide protection from wind and rain on mild days, but it can turn into a source of harm during strong storms! Use fewer temporary facilities and opt for more standardized design; it may cost more, but that’s the right approach
