A blizzard is a severe snowstorm that is characterized by high winds, low visibility, and significant snowfall. The term "blizzard" was first used in the late 19th century to describe a severe snowstorm in the United States. Blizzard conditions are typically defined as sustained winds of at least 35 mph, visibility of less than 1/4 mile, and significant snowfall that lasts for an extended period, usually at least 3 hours.
Characteristics of a Blizzard
A blizzard is a complex weather phenomenon that involves the interaction of multiple atmospheric and environmental factors. The key characteristics of a blizzard include strong winds, heavy snowfall, and low visibility. The strong winds in a blizzard are typically the result of a strong low-pressure system that forms over a region, causing the air to rise and cool, resulting in the formation of snow. The heavy snowfall in a blizzard is often the result of a combination of factors, including the presence of moisture in the air, the lift of the air over a region, and the cooling of the air as it rises.
Types of Blizzards
There are several types of blizzards, including lake-effect blizzards, nor’easters, and blizzard conditions associated with winter storms. Lake-effect blizzards occur when cold air passes over a large body of warm water, such as one of the Great Lakes, causing the air to rise and cool, resulting in the formation of heavy snow. Nor’easters are powerful winter storms that form along the East Coast of the United States, often bringing heavy snow, strong winds, and coastal flooding. Blizzard conditions can also occur in association with winter storms, which are large-scale low-pressure systems that bring snow, freezing rain, and strong winds to a region.
| Blizzard Type | Characteristics |
|---|---|
| Lake-Effect Blizzard | Forms when cold air passes over a large body of warm water, resulting in heavy snow |
| Nor'easter | Powerful winter storm that forms along the East Coast, bringing heavy snow, strong winds, and coastal flooding |
| Winter Storm Blizzard | Large-scale low-pressure system that brings snow, freezing rain, and strong winds to a region |

Impact of Blizzards
Blizzards can have a significant impact on daily life, including disrupting transportation, causing power outages, and affecting economic activity. The strong winds and heavy snowfall associated with blizzards can make travel extremely difficult, if not impossible, and can also cause significant damage to buildings and infrastructure. In addition, blizzards can have a major impact on the economy, particularly in industries such as transportation, retail, and hospitality.
Preparation and Response
Preparation and response are critical components of managing the impact of blizzards. This includes having a plan in place for emergency situations, such as a winter storm emergency kit, and staying informed about weather conditions through trusted sources such as the National Weather Service. It is also important to take steps to protect property, such as insulating pipes and sealing drafts, and to have a plan for alternative heat and lighting in case of a power outage.
| Preparation Step | Description |
|---|---|
| Emergency Kit | A winter storm emergency kit should include items such as food, water, first aid supplies, and a battery-powered radio |
| Property Protection | Take steps to protect property, such as insulating pipes and sealing drafts, to prevent damage from cold temperatures and wind |
| Alternative Heat and Lighting | Have a plan for alternative heat and lighting, such as a portable generator or flashlights, in case of a power outage |
