Where does it snow at the equator?
Snow falls at sea level poleward of latitude 35° N and 35° S, though on the west coast of continents it generally falls only at higher latitudes. Close to the equator, snowfall occurs exclusively in mountain regions—at elevations of about 4,900 metres (16,000 feet) or higher.
How does latitude affect the snow line?
Beyond the Tropics, the snow line becomes progressively lower as the latitude increases, to just below 3,000 metres (9,843 ft) in the Alps and falling all the way to sea level itself at the ice caps near the poles. In addition, the relative location to the nearest coastline can influence the altitude of the snow line.

Where does it snow the most?
Not surprisingly, the most snow was on the ground in the far north where temperatures were coolest. Latitude is not the only thing that influences temperature and snow cover. Arcs of cold blue and snow cut across otherwise warm, snow-free areas in Asia, Europe, and Africa. These seemingly out-of-place cold areas are mountain ranges.
Where does snow fall?
Snow falls at sea level poleward of latitude 35° N and 35° S, though on the west coast of continents it generally falls only at higher latitudes. Close to the equator, snowfall occurs exclusively in mountain regions—at elevations of about 4,900 metres (16,000 feet) or higher.
How much of the Earth's surface is covered by snow?
snow, the solid form of water that crystallizes in the atmosphere and, falling to the Earth, covers, permanently or temporarily, about 23 percent of the Earth’s surface.
What are the different types of snow particles?
Frozen precipitation has been classified into seven forms of snow crystals and three types of particles—graupel (granular snow pellets, also called soft hail), sleet (partly frozen ice pellets), and hail (hard spheres of ice). The texture and density of fallen snow undergo constant change.
How are snowflakes formed?
Snowflakes are formed by crystals of ice that generally have a hexagonal pattern, often beautifully intricate. The size and shape of the crystals depend mainly on the temperature and the amount of water vapour available as they develop.
How does snow cover affect the climate?
By increasing the reflection of solar radiation and interfering with the conduction of heat from the ground, it induces a cold climate.
What temperature do ice crystals form?
At temperatures above about −40 °C (−40 °F), ice crystals form around minute particles of dust or chemical substances that float in the air; at lower temperatures, crystals form directly from water vapour. If the air is humid, the crystals tend to grow rapidly, develop branches, and clump together to form snowflakes.
Does snow change texture?
The texture and density of fallen snow undergo constant change. Snow on the ground tends to become increasingly dense, and, where it survives spring and summer melting for years, it may turn into ice and form a glacier.
Which region receives more snowfall?
Regions which lie near the coast usually receive more snowfall than areas situated further inland. As a result, the snow line of coastal regions is usually lower than that of regions found away from the coast. Ocean currents also affect the altitude at which the snow line is found.
How high is the snow line?
On the equator, the snow line is usually found at an altitude of 15,000 feet above sea level. The position of the snow line varies as one moves away from the equator and reaches as high as 18,700 feet above sea level in the Himalayas which lie near the Tropic of Cancer.
What is the snow line in the Himalayan Mountains?
The general definition of the term “snow line” is the boundary which separates areas which are covered with snow and areas that are not. However, the term can have different definitions depending on the context in which it is used and, therefore, there exist different types of snow lines.
What causes snow to be lower in the northern hemisphere?
The face of a slope also affects the position of the snow line with north-facing slopes in the northern hemisphere receiving less solar exposure and, therefore, has a lower snow line than southern-facing slopes.
How is snow line measured?
Measurement. Measuring the snow line does not require to be done on-site, with modern technology making it possible to be done remotely. The snow line is measured through in different ways including the use of satellite images, aerial photography, and automatic cameras. These high-tech measurement methods have high accuracy levels ...
Why is the snow line not fixed?
The snow line is not fixed and responds to changes in global temperatures. The ongoing climatic change has affected the position of the snow line in all parts of the world. Some mountains have their snow disappearing in the past few decades, which is attributed to increasing global temperatures caused by human activity.
Is the snow line higher than it was thousands of years ago?
Scientists believe that the current snow line is much higher than it was thousands of years ago. According to numerous studies, the snow line was between 2,000 feet and 4,000 feet lower in the last glacial period than it is presently. Joseph Kiprop November 6 2018 in Environment. Home.
How high is the snow line?
The interplay of altitude and latitude affects the precise placement of the snow line at a particular location. At or near the equator, it is typically situated at approximately 4,500 metres (14,764 ft) above sea level. As one moves towards the Tropic of Cancer and Tropic of Capricorn, the parameter at first increases: in the Himalayas the permanent snow line can be as high as 5,700 metres (18,701 feet), whilst on the Tropic of Capricorn, no permanent snow exists at all in the Andes, because of the extreme aridity. Beyond the Tropics, the snow line becomes progressively lower as the latitude increases, to just below 3,000 metres (9,843 ft) in the Alps and falling all the way to sea level itself at the ice caps near the poles.
How low is the snow line in the Alps?
Beyond the Tropics, the snow line becomes progressively lower as the latitude increases, to just below 3,000 metres (9,843 ft) in the Alps and falling all the way to sea level itself at the ice caps near the poles. In addition, the relative location to the nearest coastline can influence the altitude of the snow line.
What is the boundary between the accumulation zone and the ablation zone on glaciers called?
The boundary between the accumulation zone and the ablation zone on glaciers is called the "annual snow line". The glacier region below this snow line was subject to melting in the previous season. The term "orographic snow line" is used to describe the snow boundary on surfaces other than glaciers.
Why is the snow line important?
Because the snow line can be established without on-the-ground measurements, it can be measured in remote and difficult to access areas. Therefore, the snow line has become an important variable in hydrological models.
How high is the snow line in the Himalayas?
As one moves towards the Tropic of Cancer and Tropic of Capricorn, the parameter at first increases: in the Himalayas the permanent snow line can be as high as 5,700 metres (18,701 feet), whilst on the Tropic of Capricorn, no permanent snow exists at all in the Andes, because of the extreme aridity.
What does a higher glacier line mean?
A higher glacier equilibrium line will indicate that the glacier is shrinking, whereas a lower line will indicate that the glacier is growing. The terminus of a glacier advances or retreats based on the location of this equilibrium line.
What is the snow line?
Snow line is an umbrella term for different interpretations of the boundary between snow-covered surface and snow-free surface. The definitions of the snow line may have different temporal and spatial focus. In many regions the changing snow line reflect seasonal dynamics.
What temperature does snow form?
Snow forms when the atmospheric temperature is at or below freezing (0 degrees Celsius or 32 degrees Fahrenheit). There also needs to be a certain amount of moisture in the air for it to snow. Funnily enough, it can be too warm to snow, but it can never be too cold.
