What is a blizzard and what causes it?

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.

What is blizzard in geography?

How are blizzards categorized?

It’s a difficult call to make, because unlike other natural disasters, snowstorms have no categorization system. To fully categorize a storm, NOAA’s proposed Regional Snowfall Impact Scale, or ReSIS, takes into account societal impact and relies on population density as well as the actual amount of snow.
