The Arctic is often characterised by snow, the northern lights and extreme cold. While those aspects of life here can be true, I have found a more complex situation and a sometimes delicate beauty. For example this video shows what can happen when the snow is late. This year the snow arrived on time or even a bit early, so in that case we can settle in to the winter we know. But when the temperatures continue to sink before snow covers the ground, a different picture can emerge, if conditions are right.
A couple of years ago I decided I’d drive across to the nearest island before we lost daylight to the polar night. I wanted to get some new drone footage and the sky was such a beautiful pink I hoped to capture it. We had ice in the ‘city’ but I hadn’t anticipated the beauty I would see where the landscape was more open and maybe slightly colder due to topographical differences. Our usual ice is like the road, just flat and white, sometimes thick and often slippy. In the video all the white you see (except the very tops of the distant mountains) is not snow but ice. It was like a garden of ice flowers and if I knew the words to the ‘Frozen’ theme song maybe I would have been singing that. As it was my mouth was just hanging open in wonder and joy.
I absolutely love days where I see something new and I didn’t even know this type of ice was possible. I’m glad I got to capture a little of what I saw and I hope you like it too. This was the first time I had seen this type of ice, even after five years in the Arctic. And to be honest, I didn’t really know how it happened. When I did a little research I found it rather fascinating so I thought I’d share what I learned with you too.
Frost and ice form when water vapour in the air undergoes a phase change into solid ice. Frost occurs when water vapour directly deposits onto a surface as ice crystals because the surface temperature is below the freezing point and the air is moist. Ice forms when liquid water, such as a puddle or dew, freezes as its temperature drops to or below the freezing point, which is 0°C/32°F.
HOW FROST FORMS
❅ Deposition : This is the most common way frost forms. When the air temperature is below freezing and the frost point (which is below freezing) is reached, water vapour bypasses the liquid phase and changes directly into ice crystals, forming ‘white frost’ or ‘hoar frost’. This process creates intricate, crystalline patterns.
❅ Freezing : This happens when a surface is first covered in liquid dew, and then the temperature drops below freezing. The dew drops, which were once liquid, freeze into solid ice, forming ‘frozen dew’.
HOW ICE FORMS
❅ From Fog : Rime ice forms when supercooled water droplets in fog or mist freeze on contact with
surfaces that are below freezing. It creates an opaque, white coating that can build up on trees and other objects, especially at higher elevations.
❅ From Water : Ice forms when a body of liquid water, like a puddle or a pond, cools down to its freezing point. As the water loses heat, the molecules slow down and lock into a rigid, crystalline structure, which is solid ice.
❅ Freezing Rain : This happens when rain falls on a surface that is at or below freezing. The rain freezes on contact, creating a smooth, often glassy layer of ice.
❅ Black Ice : This is a thin, transparent layer of ice that forms when light rain or drizzle freezes on a sub-freezing surface.
FACTORS THAT PROMOTE FROST AND ICE FORMATION
❅ Cold Temperatures : The most critical factor is a surface temperature at or below freezing.
❅ Clear Skies : Clear nights allow heat from the Earth's surface to radiate into space more quickly, causing surfaces to cool to below-freezing temperatures faster than they would on a cloudy night.
❅ Calm Winds : Light winds or calm air allow cold air to settle in low-lying areas, while strong winds can mix the air, which can prevent frost from forming.
❅ High Moisture in the Air : A sufficient amount of water vapor in the air is necessary for both depositional frost and liquid water to condense and then freeze.
❅ Topography : Cold air is denser than warm air and sinks, so it collects in low-lying areas like valleys and frost hollows, making them more prone to frost and ice formation.
