How A Blizzard Forms?

One condition required for a blizzard to form is a mass of warm air rising over cold air. This causes strong, cold winds and precipitation to fall. A blizzard will then occur if temperatures are below freezing at ground level and in the clouds, and there is enough moisture in the air to allow clouds and snow to form.Mar 14, 2017

What are the main causes of blizzards?

What causes a Blizzard? In general, blizzards occur when a mass of warmer air collides with a mass of very cold air. The cold air mass cuts under the warm air mass, and as the warm moist air rises upwards it forms snow. The collision of the air masses also provides the atmospheric tension required for high wind speeds.

The cold air is forced under the lighter warm air, which in turn cools and releases its moisture. The moisture drops through the cold air mass, freezing and falling as snow. The effects of the low pressure and the mountains result in high winds that blow the snow and create the blizzard conditions.
