Strange natural phenomena only occur when it is cold

Cold weather affects many people, but it is also the cause of interesting natural phenomena on Earth.

Winter with sweet cold can make many people feel excited about being able to hug the bear everywhere but when the weather temperature falls too low, many people will be surprised when these strange natural phenomena occur out there!

first.

It sounds fairy-tale but when the temperature drops below minus 11 degrees Celsius, we can freeze the bubble.

The secret to creating ice bubbles is to blow the ball into the air so that they have time to freeze before reaching the ground or crumbling. The surface of the bubble will form crystalline tissue, which looks a bit like a cracked eggshell.

You think the waves can't freeze? No, you're wrong.

Because salt water can also freeze like fresh water but at lower temperatures. The freezing temperature of seawater is about -2.2 degrees Celsius. The ripples when freezing will thicken, moving strangely slowly.

This is considered one of the rare natural phenomena - "ice cream cake". These "cakes" are as big as a plate, appearing when the snow crystals in the water are far from the shore.

At this time there will be no more waves rolling them into spheres, instead they will float and accretion gradually into flat slabs.

4.

The cold air is very heavy, which means that the molecules are closer to each other and there is very little room for the water to evaporate.

When hot water is "knocked out", the cold, dry atmosphere will prevent water molecules from binding as they were. At this time, the vapor precipitate will cling to airborne particles such as sodium or calcium, forming snow crystals as we see them.

5.

The phenomenon of the Sun halo - Sun halo - appears when the sunlight above the sky passes through ice crystals in the air.

However, according to research from the University of Illinois (USA), the crystal particles must be hexagonal with a diameter of less than 20.5 micrometers, and the light angle must be 22 degrees. This shape and size allows light to be refracted twice, helping the Sun's halo to form.

This is a strange phenomenon, only occurs when there is a combination of temperature, humidity, wind speed, terrain and sloping terrain.

According to experts, snow rolls form in the hillside, the surface is covered by a layer of smooth or hard snow. The snow will fall, piling up on the ground. The snowballs will gradually roll down the slope, the longer the slope, the bigger the diameter of the snow.
