How does snow form?

When you see snow, it can be hard to imagine how it forms. But in fact, snow is made of water vapor – water that’s in the form of gas.

The vapor condenses on particles like dust, ash or pollen in the air. When the temperature goes cold enough, the water vapor freezes around these solid particles and creates an ice crystal. The resulting ice crystal is called a snowflake.

Water Vapor

Water vapour, the gaseous state of water, is one of the key elements of Earth’s climate. It is important for both the hydrologic cycle and the atmospheric greenhouse effect.

The amount of water vapor in the atmosphere is dependent on many factors, including temperature and geographical location. It is particularly abundant in the lower troposphere, where a major part of the water cycle occurs, and in the upper troposphere, where most of the greenhouse effect takes place.

Measurements of atmospheric water vapor are made in a variety of ways, including using radar, radiometers, and satellite measurements. These measurements provide valuable information on how air moves in the atmosphere and help us understand how water vapor affects weather and climate.

Observations of water vapor in the atmosphere are a necessary step for predicting long-term changes in global climate. They can also help to better understand how water vapor behaves during extreme events such as floods, tornadoes, and hurricanes.

Atmospheric water vapor is measured in several different ways, including using a combination of humidity measurements and the mixing ratio. These include vapor pressure, specific humidity, dew point, and relative humidity.

Temperature and incoming sunlight can affect the amount of water vapor in the atmosphere. For example, in the tropics, water vapor concentrations are high in the north hemisphere during summer and low in the south hemisphere during winter. This is because a band of extremely humid air known as the Intertropical Convergence Zone (ITZ) is influenced by seasonal temperature changes and incoming sunlight.

Snow forms when a mass of water vapor gathers and condenses in colder layers of the atmosphere, such as during a winter snowstorm. This can happen in a number of different ways, including collisions between moist air masses or the cooling effect of mountains.

Another way snow forms is when water vapor condenses onto particles floating in the atmosphere, such as dust or smoke. These particles are called condensation nuclei and are crucial for the formation of clouds and precipitation.

Because water vapor is the main source of snow, increasing its presence in the atmosphere could lead to more snowfall worldwide. However, this is uncertain and may have a negative feedback impact on climate as well. If more water vapor leads to more cloud formation, then the amount of condensed water in the atmosphere would increase, which can result in a stronger greenhouse effect.

Cold Temperature

Snow falls when temperatures are low enough for moisture to condense out of air and form tiny ice crystals. The temperature of the air near the ground can also affect how much snow will fall.

Generally, warmer air can hold more water vapor than colder air. But that doesn’t mean cold air is always unable to produce snow.

Temperatures that are cold enough to prevent snow from forming are rare. Often, it’s because the atmosphere is so dry that the cold air cannot hold as much moisture.

The exact temperatures required to produce snow vary with the terrain, prevailing wind patterns and air pressure. The ideal temperature is a balance of the three factors, but in most cases, warmer air is more conducive to snow formation.

When temperatures are just right, the ice crystals stick together to form snowflakes that become heavy enough to fall to the ground. They’re small, powdery and dry if the air is extremely cold, but larger and more wet when it’s slightly warmer.

Another common way that snow forms is when it is sleet or freezing rain. Sleet, also known as ice rain, is formed when precipitation (rain or snow) first falls through a layer of air that is above freezing and then melts as it passes through a layer of much colder air. The ice then re-freezes back into snow as it reaches the ground.

Freezing rain, on the other hand, occurs when precipitation (rain or snow) passes through a layer of warm, expanding air that is able to hold more moisture than the cold air it encounters. This process is called expansion cooling, and it causes the warm air to expand and become cooler.

These two processes make it possible for sleet and freezing rain to form when the weather is below 0degC, but not when it’s above 0degC. These conditions are more common in mid-latitude regions than high latitudes, since the warm air is higher and it’s easier for advection to bring in moisture from other areas.

Wet snow, on the other hand, is more common in plains and mountainous areas where it can cause a lot of disruption to road and rail traffic. This type of snow is heavy and can adhere to anything it touches, including cars. It can also freeze quickly and turn into black ice.


Humidity plays a big role in how snow forms. It can make or break the shape of snow, and it affects how quickly ice melts on the ground.

The amount of moisture in the air can be measured with relative humidity (RH), which is a percentage that compares the amount of water vapor to how much water the air can hold at a certain temperature. The more water a pocket of air can hold, the higher its RH will be.

It also can affect how much rain or snow falls from a cloud. If enough moisture is present higher in the atmosphere, then cloud droplets can grow into raindrops and snowflakes. In places where the RH reaches a level of 80% or higher, rainfall may continue to fall throughout the day.

If the humidity is very low, however, some of that precipitation can evaporate before it hits the ground. This process is called virga.

Virga is also a major factor in the transmission of airborne viruses. A National Academy of Sciences study has found that the flu virus can spread more easily and survive longer in lower humidity environments.

This is because low humidity makes it difficult for germs and viruses to move, as they simply can’t be suspended in the air like they could in a humid environment. A higher relative humidity level in the 40%-60% range works to deactivate airborne viruses, preventing them from spreading and helping to keep you healthy and your family free of infections.

Another important effect of humidity is that it can influence the health of animals. Animals need to perspire to regulate their internal body temperatures, so it is important that the vapor from the skin’s surface be able to quickly escape into the environment.

During fall and winter, many people suffer from asthma and other respiratory disorders that can be aggravated by low humidity. These symptoms can include itchy skin, dry nasal passages and coughing. A drop in humidity can also exacerbate allergies, as dust and other allergens become more prominent in the home.


When clouds form, the water vapor in the air cools enough to change from gas to liquid or solid. This causes the droplets in a cloud to get heavy, which causes them to fall. This process is called condensation. It is the process that gives rise to rain, snow, sleet and hail.

When the temperature of a cloud is too cold, the water vapor freezes directly into ice crystals. These ice crystals may stay up in the clouds, or they can fall to earth as snowflakes.

Ice crystals can also be formed from tiny particles of dust or salt floating in the atmosphere. Without these tiny particles, cloud condensation and rain or snow would not occur.

The particles that are used as a base for ice crystals or raindrops are called ice nuclei. If the air temperature is too warm for ice to form, cloud seeding is a weather modification technique that uses tiny ice nuclei to improve a cloud’s ability to produce precipitation.

In most cases, a cloud cannot grow upwards because the cooling rate for air in the upper atmosphere is too slow. However, there are some exceptions to this rule, such as cirrus clouds, which develop at an average altitude of 20,000 feet.

During this process, the heat from the sunlight that is absorbed by the ice in the clouds is unable to escape. The temperature at the top of a cloud reaches about -10 degrees Celsius (14 degrees Fahrenheit) and is just cold enough for ice to start forming.

Once the ice crystals form, they grow by colliding with each other. They eventually get to a size that is large enough to fall, where they stick together to form larger, symmetrical snow crystals.

In addition to the ice crystals, snowflakes can contain small pieces of silicate materials that are clay minerals or micas. These materials act as the core of a snow crystal, and they help the crystal grow by collecting water vapor from the air.
