Do you know that if snowflakes are big, we won’t get much snow, but if they’re small we’ll get a lot more snow. Is there any science behind this?
Yes there is a science, when temperature is just a little above freezing near the ground, the falling snowflakes are already melting on the way down. The wet snowflakes stick together, forming bigger flakes that melt as soon as they hit the ground or soon after, as temperatures continue to rise. Even if they don’t melt, they won’t pile up as high because they contain so much liquid water.
When the air is colder, the snowflakes are smaller because they’re not sticking together. And when it is very cold, the snow can sometimes be very small. This is the kind of snow that will pile up or blow around, and because temperatures are so cold, they won’t melt for awhile. So when it comes to snowflakes, be more concerned about the small ones and don’t sweat the big stuff!
