The scale was developed by meteorologists Paul Kocin and Louis Uccellini, and ranks snowstorms from Category 1 (“notable”) to Category 5 (“extreme”). Only two historical blizzards, the 1993 Storm of the Century and the North American blizzard of 1996 are rated in the 5 “extreme” category.

A Category 5 Extreme ranking is indicated by a numerical score of 18 or higher on the scale. Out of the over 500 historical storms assessed since 1900, only twenty-six storms have been given a Category 5 ranking. The highest ranking storm on the list is the Great Blizzard of 1978 which scored a value of 39.07.
Are there different levels of blizzards?
There are 3 types of ground blizzards: vertical advection, horizontal advection, and thermal mechanical. Vertical advection blizzards have an “upward draft of wind blowing the snow high into the atmosphere to create waves hundreds of feet high” (Jones, 2017).
Are there different types of snowstorms?
Types of Winter Storms. Snowstorms are one type of winter storm. Blizzards are snowstorms with high winds, and lake effect storms are snowstorms that form near the Great Lakes. Ice storms can bring freezing rain or sleet as well as snow.
What are the characteristics of a blizzard?
What is a Blizzard? The National Weather Service defines a blizzard as a storm with large amounts of snow or blowing snow, winds greater than 35 mph (56 kph), and visibility of less than ¼ mile (0.4 km) for at least three hours. Some blizzards, called ground blizzards, have no falling snow.
What are the parts of a blizzard?
A blizzard is a long-lasting snowstorm with very strong winds and intense snowfall. You need three things to have a blizzard; cold air at the surface, lots of moisture, and lift.
How are snow storms classified?
It’s a difficult call to make, because unlike other natural disasters, snowstorms have no categorization system.
What makes a blizzard different from a regular snowstorm?
In the United States, the National Weather Service defines a blizzard as a severe snow storm characterized by strong winds causing blowing snow that results in low visibilities. The difference between a blizzard and a snowstorm is the strength of the wind, not the amount of snow.
How do you identify a blizzard?
- Sustained wind or frequent gusts of 35mph or greater.
- Considerable falling and/or blowing snow reducing visibility to under a quarter mile.
How do meteorologists categorize a blizzard?
The National Weather Service of the United States defines a blizzard as a storm with winds of more than 56 km (35 miles) per hour for at least three hours and enough snow to limit visibility to 0.4 km (0.25 mile) or less.
What are the names for the 2021/22 season?
The 2021-22 season is the 10th season The Weather Channel is naming winter storms.
How is a hurricane categorized?
The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane’s sustained wind speed. This scale estimates potential property damage. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage.
What category was the Iran blizzard?
Type | Extratropical cyclone Winter storm Blizzard |

Snow comes in five general types: graupel, plates, needles, columns, and dendrites. Each snow type forms in different temperatures and moisture levels.
What are the three forms of winter storms?
A winter storm is an event in which the main types of precipitation are snow, sleet or freezing rain.
What is the measurement scale for blizzards?
A blizzard is one type of storm that has no scale in which to measure its intensity. A blizzard’s strength is measured by an estimate based off of total snowfall and wind speeds.
What type of front is associated with blizzards?
The typical ground blizzard occurs when an Arctic cold front moves through the region, causing temperatures to drop and winds to increase quite rapidly, often reaching gusts of 50 to 60 mph.
Why is it called an Alberta clipper?
Alberta clippers take their name from Alberta, the province from which they appear to descend, and from clipper ships of the 19th century, one of the fastest ships of that time.
What type of weather is a blizzard?
Blizzards are dangerous winter storms that are a combination of blowing snow and wind resulting in very low visibilities. While heavy snowfalls and severe cold often accompany blizzards, they are not required. Sometimes strong winds pick up snow that has already fallen, creating a ground blizzard.
What states have blizzards?
North Dakota, South Dakota and western Minnesota led the nation in recorded blizzards in a review of severe winter weather from 1959-2000, said Robert Schwartz, a geography professor specializing in the study of blizzards.
What are the 3 criteria for a blizzard?
It defines a blizzard by three criteria: blowing or falling snow, winds of at least 35 miles per hour, and visibility of a quarter-mile or less for at least three hours. “Whether or not the snow falls during the time of the blizzard, dangerous conditions can result,” a Weather Service Twitter account said on Friday.
What wind speed is a Category 5 hurricane?

Is a squall worse than a blizzard?
The two types of events differ in duration. Lake effect snow squalls can extend long distances inland and can persist for many hours. Snow accumulations can exceed 6 inches in a matter of hours. Snow squalls, while they have similar characteristics, are not the same as blizzards.
Is a blizzard high or low pressure?
The strong winds of a blizzard form because of a difference in pressures between two systems. These pressure systems are the low pressure system which is causing the stormy weather and the high pressure system on the back side of the low pressure system.
How do you survive a blizzard?
- Water and non-perishable food for several days.
- Extra cell phone battery or charger.
- Battery-powered or hand crank radio that can receive NOAA Weather Radio tone alerts and extra batteries.

Story highlights. In the United States, tropical storms and hurricanes are the only kinds of storms that get a name: Irma, Katrina, Harvey, Sandy. Other major storms – tornadoes, severe thunderstorms and blizzards – aren’t as special.
How do the UK name storms?
The criteria we use for naming storms is based on our National Severe Weather Warnings service. This is based on a combination of both the impact the weather may have, and the likelihood of those impacts occurring. A storm will be named when it has the potential to cause an amber or red warning.
Why do they name hurricanes?
Hurricanes are given names so that meteorologists can identify them and track them across the oceans. Since there are sometimes multiple hurricanes at a particular time, naming them helps to avoid confusion.

However, the biggest blizzard that was ever recorded was the blizzard of 1972 in Iran. Low temperature and strong winds are the two conditions that lead to the Iran blizzard of 1972. This resulted in the deaths of thousands of people and no warning was provided to the villagers of how they wouldn’t get any heat.

Graupel is sometimes mistaken for hail, but tends to have a texture that is softer and more crumbly. Graupel is sometimes also called snow pellets. Polycrystals are snowflakes composed of many individual ice crystals.
What are the 7 main shapes of a snowflake?
This system defines the seven principal snow crystal types as plates, stellar crystals, columns, needles, spatial dendrites, capped columns, and irregular forms.
What causes blizzards to form?
For a blizzard to form, warm air must rise over cold air. There are two ways that this may happen. Winds pull cold air toward the equator from the poles and bring warm air toward the poles from the equator. When warm air and cold air are brought together, a front is formed and precipitation occurs.
How is your weather named or classified?
This system is called the F-Scale or Fujita Scale; it classifies tornadoes by their estimated wind speed, which is determined by looking at how strong the wind must have been to cause the resulting damage. Tornadoes are classified into five categories, F-0 through F-5.

What’s a nor’easter storm?
A Nor’easter is a storm along the East Coast of North America, so called because the winds over the coastal area are typically from the northeast. These storms may occur at any time of year but are most frequent and most violent between September and April.
