If the temperature from the ground to way up in the sky is below freezing throughout, the snow will stay cold all the way down to the ground, and will have low liquid content. The more liquid there is in the snow, the heavier it becomes.

Snow tends to accumulate better on grass surfaces than concrete surfaces for several reasons. (1) A road surface is connected directly to the earth’s surface. Vegetation and grass is more exposed to the cold air. (3) The shadow effect in grass and vegetation allows for less melting of snow.

grass and soil. The soil depending on its quality can be more aerated or less. Thus, contributing to less heat conduction and exposure of less surface area for the snow to fall on and melt. Now you know why snow melts faster on the sidewalk than it does on grass.

Snow’s effect on climate Seasonal snow is an important part of Earth’s climate system. Snow cover helps regulate the temperature of the Earth’s surface, and once that snow melts, the water helps fill rivers and reservoirs in many regions of the world, especially the western United States.

Snow days provide parents and children with the perfect storm of having a day off to explore the outdoors while having some fun to boot. People can even absorb Vitamin D on cloudy days, which we all lack in the winter.

There are a few drawbacks to snow. Heavy snow can damage trees and shrubs as the weight accumulates on branches. If there are heavy snows, carefully brush off snow from branches. The other drawback of snow in the landscape is small animals, such as voles (field mice) are now protected from predators.

Your primary concern for surviving harsh winter conditions may be making it to May without frostbite, but the snow is bad for your skin just as much as your extremities when the temperatures plummet.

After examining the chemical reactions that took place, the researchers discovered that snow was efficient at removing pollutant particles from the air. In fact, after just one hour, the snow’s concentration of chemicals from exhaust — such as benzene, toluene, ethylbenzene and xylenes — increased dramatically.

So yes, snow is a good thing for your lawn during the dormant winter months. It’s also good for the sake of the ground water supply. Snow eventually melts, of course, and that water is absorbed into the water table beneath ground level and acts as a moisture reserve during the hot dry months of summer.

Normal Seed Planting Many types of grass seed are very sensitive to cold. Grass seed is designed to sprout in response to moisture and the proper soil conditions. In general, the grass seed will survive but delay its sprouting time. If the seed has already sprouted, the snow could easily kill the seedling.

What’s the best grass height for winter? Ultimately, your lawn should be about 2 to 2 ½ inches high by wintertime. That’s the “sweet spot” because it’s not too tall to invite snow mold, but not too short to be stressed out by cold weather. Spread the trims out, so you condition the lawn to withstand a shorter height.

We don’t recommend throwing down grass seed on the snow, since that leads to very uneven seed distribution when the snows melt and water runs down slopes and off the lawn. Mid-February through late March is a good time to sow cool-season grass seed.
