The snow is turned into ice by the motion of the waves, creating huge frozen ice balls.PowerPoint Presentation: Thousands of balls of ice the size of a football, huddle along the shore in a wonderful show. For this to happen the water temperature should be 0 ° C. A phenomenon known as "Lolly" by the fishermen of the Canadian Island of Cape Breton.PowerPoint Presentation: SNOW ROLLERSPowerPoint Presentation: A curious meteorological phenomenon of cylindrical snow formations known as SNOW ROLLERS is rare because the precise conditions must be present for their formation.PowerPoint Presentation: .PowerPoint Presentation: - The frozen surface or ice covered area should glide with ease to make a roller. -The ice must be covered with a 2 cm moist layer thick powder snow and the temperature must be close to the point where ice melts.PowerPoint Presentation: - The air temperature must be equal to or slightly above freezing, between 0 and 1 ° C. -The wind must be approximately 40 km / hour to roll the snow .PowerPoint Presentation: - A gust of wind takes the snow along like a spoonful of ice cream. Each gust of wind increases its size .PowerPoint Presentation: The size of the cylinders may reach several centimeters and one roller had a diameter of 70 cm.PowerPoint Presentation: Finally, when the roll is too heavy to be pushed by the wind or comes against an obstacle, it stops, leaving a trail behind.PowerPoint Presentation: Gravity also forms snow rollers. The snow falls from a tree on a slope and rolls down, forming a sphere.PowerPoint Presentation: EINDE You do not have the permission to view this presentation.
