Snow Rollers
Snow rollers resemble white bales of hay. They are a rare meteorological phenomenon because conditions have to be just right for them to form:
Thin surface layer of wet, loose snow;
Temperature near melting point of ice;
Thin substrate such as ice or powder snow;
Wind must be strong enough to blow the snow but not so strong that it blows the
roller apart.
Several years ago, on a crisp winter day, I was fortunate to see snow rollers in a field
off a busy city street next to an apartment complex on one side and a grocery store on the other. I’d never seen anything like it before, or since, not even in that same field.
