Many times, a snow roller is actually hollow through the middle.
As it picks up more snow, the roller looks like someone started to roll snow for a snowman, then simply got up and left-or a roll of toilet paper, depending on how poetic you feel. “Snow rollers” occur when a chunk of snow gets rolled along the ground by the wind. Why go to all the effort to roll piles of snow for a snowman when you can get nature to do it for you? If you live in Manitoba, that might just be possible. Snow rollers Photo by Salvi 5/Wikimedia Commons How dramatic are chinooks? Well, Pincher Creek had a record temperature rise of 41 degrees in one day: from -19 to 22 in an hour. Chinooks happen most often in a stretch from Pincher Creek and Crowsnest Pass to Lethbridge-although Calgary’s also famous for its warm winter winds. What causes parts of the province to get four seasons in one day? Wet winds blow in from the Pacific coast, lose their moisture as they climb the Rockies, then warm as they blow down the other side of the mountain. But actually, southern Albertans get regular reprieves from winter’s grip, thanks to the warm chinook winds that blow over the Rockies. Those of us who don’t live in Alberta tend to think of the province as a land of deep-freezing winter, at least from October to May. If this happens often enough, large ice balls form, and eventually wash up on the shore. If the temperatures are just right, the face of the ball that hits the wind will freeze, adding a layer of ice. No, it’s not someone with a snowman obsession-the balls or “boulders” are formed when chunks of ice are tossed around in the waves. These weird weather occurrences take the conversation beyond simple small talk.Īt certain times of the year, the shores of Lake Huron and Lake Michigan look like someone’s setting up for an epic snowball fight: the beach is covered with round balls of ice, about the size of a basketball. Sometimes, though, things get really weird-and then we’ve really got something to talk about. And that’s when the weather’s acting…well, as normal as it gets. Whether it’s freezing cold or boiling hot, raining, snowing, fogging, or all three at once, meteorology is our way of breaking the ice, so to speak. Forget about lacrosse (or hockey, for that matter)-discussing the weather is Canada’s real national sport.
