- For snow to fall, moisture must be present in the atmosphere. Snowstorms also rely heavily on temperature, but not necessarily the temperature we feel on the ground. Snow forms when the atmospheric temperature is at or below freezing (0°C or 32°F). If the ground temperature is at or below freezing, the snow will reach the ground.

How does weather affect the characteristics of snow?
Snow may fall as symmetrical, six-sided snowflakes, or it may fall as larger clumps of flakes. Similarly, once snow is on the ground, the snowpack may assume different qualities depending on local temperature changes, whether winds blow the snow around, or how long the snow has been on the ground.
Feb 14, 2024 · Let’s assume a steady snow falls for the entire 24-hour period at a rate of 2.0 inches (5.1 cm) per hour. If the snow board were cleared every hour, the daily snowfall would be 48.0 inches (122...
- Elevation. Canada is far from flat, and elevation plays a big role in temperatures. The higher you are above sea level, the cooler you will be.
- Proximity to water. This one requires a little bit of science. Because air is thinner than water, it can change its temperature rather quickly.
- Latitude. This one is rudimentary, but does play a big role. The farther north you are, you could typically see earlier snowfall. This is because you are closer to the cold, Arctic air that is required for the flakes to fall and to also keep them on the ground.
There are four main mechanisms for movement of deposited snow: drifting of unsintered snow, avalanches of accumulated snow on steep slopes, snowmelt during thaw conditions, and the movement of glaciers after snow has persisted for multiple years and metamorphosed into glacier ice.
Science. Why it matters. Quick Facts. What is snow? Snow is precipitation that forms when water vapor freezes. Snow falls as ice crystals from clouds when temperatures drop below freezing and there is enough humidity in the air. Snowflakes appear under a low temperature scanning electron microscope.
Quick Facts. Why it matters. We all associate snowstorms with cold weather, but snow's influence on the weather and climate continues long after the storm ends. Because snow is highly reflective, a vast amount of sunlight that hits the snow is reflected back into space instead of warming the planet.
1 day ago · Toronto averages about 9 cm of snow every November. We’ve seen much more than that in some seasons. November 1940 brought the city a whopping total of 61 cm of snow. Communities in the snow ...
