Types of Snowstorms (Snow squall, Blizzard & Lake-effect snowstorms)
1- Snow squall:
Short flurries of snow that can vary in intensity but usually do not last long.
A blizzard is a brief but intense burst of heavy snow accompanied by strong, gusty winds. Unlike prolonged snowstorms, blizzards are brief but can significantly reduce visibility and create hazardous travel conditions. Here's a detailed look:
More about Snow squall:
Characteristics of a blizzard
- Duration: Typically lasts between 30 minutes and an hour.
- Visibility: Heavy snowfall and blowing snow can quickly drop to near zero.
- Wind: Often involves strong, sudden gusts, which can cause blackouts.
- Temperature: A sharp drop in temperature often accompanies blizzards.
- Deposition: Snow is usually dry and powdery, so it is easily blown away by the wind.
Formation
Snowstorms are often associated with cold fronts and occur when:
- A mass of cold, dense air turns into a mass of warm, moist air.
- The temperature difference creates instability, causing rapid upward motion in the atmosphere.
- Air loses moisture and freezes, causing sudden, heavy snowfall.
Types of Blizzards
- Frontal Snow Squalls: Occur when a cold front rapidly warms frontal air aloft.
- Lake-Effect Snowstorms: When cold air passes over a warm lake, it picks up moisture and energy and then dumps the snow inland.
Effects
- Traffic Hazards: Sudden whiteout conditions can lead to accidents and pileups.
- Temperature Drop: Freezing of wet road surfaces can lead to icy conditions.
- Disruptions: Although brief, they can delay travel and outdoor activities.
Blizzard Safety Tips
- If you're driving: Stop safely and wait until visibility improves. Avoid sudden braking.
- Stay Updated: Monitor weather alerts for blizzard warnings.
- Wear Warm Clothing: If you're caught outside, wear insulated clothing to prevent frostbite or hypothermia.
Notable Blizzard Events
- Pennsylvania, USA (2022): More than 50 vehicles pile up on a deadly highway due to an avalanche.
- Interstate 80 Blizzard (2015): Low visibility caused major travel disruptions.
Blizzards, though brief, can be extremely dangerous due to their sudden onset and severe impact on visibility and road safety. Being prepared and alert to weather updates can help mitigate risks.
2- Blizzard:
A severe snowstorm with strong winds (at least 35 mph) and reduced visibility (less than 1/4 mile) that lasts for at least three hours.
A blizzard is an intense snowstorm characterized by strong winds, heavy snowfall, and poor visibility. It is one of the most extreme forms of winter weather, capable of causing widespread disruption and serious threats to safety and infrastructure.
More about Blizzard:
- Important characteristics of a blizzard.
- Wind: Sustained winds of at least 35 mph (56 km/h).
- Visibility: Reduced to 1/4 mile or less due to snow and blowing snow.
- Duration: Conditions persist for at least three hours.
How do blizzards form?
Blizzards typically develop when:
- Cold air: A mass of cold air present at the surface.
- Moisture: A source of moisture, such as an ocean or lake, contributes to heavy snowfall.
- Lifting mechanism: Atmospheric conditions, such as low-pressure systems, force warm, moist air upward, where it cools and condenses into snow.
- Strong Winds: High pressure gradients create powerful winds, intensifying storms and causing blizzards and drifting snow.
Blizzard Effects
- Travel Disruptions: Roads become impassable, flights are grounded, and public transportation comes to a standstill.
- Infrastructure Damage: Power lines, trees, and roofs can fall from the weight of snow or wind damage.
- Health Hazards: Hypothermia, frostbite, and slip-and-fall injuries are common.
- Economic Costs: Blizzards can disrupt business, delay deliveries, and disrupt daily life.
- Safety Tips During Blizzards
- Stay Home: Avoid unnecessary travel.
- Emergency Supplies: Stock up on food, water, medicine, and flashlights.
- Dress in Layers: If you must go outside, wear warm, insulated clothing.
- Travel preparedness: Keep an emergency kit in your car, including blankets, water, and a shovel.
- Monitor weather updates: Stay informed with weather alerts and forecasts.
The most famous blizzard in history.
- Blizzard of 1888 (US): Devastating storm in the northeastern United States that dropped 50 inches of snow and killed more than 400 people.
- Great Blizzard of 1978 (US): Smashed the Midwest and Northeast, with winds of more than 100 mph and record snowfall.
- Blizzard of 1996 (US): Crippled the East Coast with massive snowfall and widespread damage.
Blizzards are powerful and dangerous, but preparation and awareness can help reduce their impact. These storms are a natural phenomenon and a significant challenge to communities and infrastructure.
3- Lake-effect snowstorms:
Heavy snowfall is caused by cold air passing over warm lake waters, which is common near large lakes such as the Great Lakes in North America.
More info about Lake-effect snowstorms:
Lake-effect blizzards
Lake-effect blizzards are intense local snowstorms that occur when cold air moves over relatively warm lake waters, picks up moisture, and deposits it as heavy snow on downwind shorelines. These storms can produce significant snowfall in narrow bands, often resulting in marked differences in snow accumulation over short distances.
How does lake-effect ice form?
- Cold air flow: Cold air, often from the Arctic, flows over a large, warm, unfrozen lake.
- Heat and moisture: The lake warms the air, causing it to gain moisture and energy through evaporation.
- Cloud formation: Warm, moist air rises and cools as it moves over land, forming clouds and precipitation.
- Snowfall: When the air reaches the cold ground, the moisture is reduced and falls as snow.
Important Factors Affecting Lake-Effect Ice
- Temperature Difference: A large contrast between lake water and air temperatures increases the intensity of snowfall.
- Get: Cold air travels over a lake. A longer recovery allows for more moisture to be collected.
- Wind Direction: Determines where snow bands will form. Small changes can dramatically change snowfall areas.
- Topography: Hills and elevations near lakes can increase snowfall rates.
Lake-Effect Blizzard Prone Areas
- Great Lakes Region (US/Canada): The most common area for lake-effect ice, especially near Lake Erie, Lake Ontario, and Lake Michigan.
- Japan: Similar typhoons occur along the Sea of Japan when the Siberian air mass crosses the warm ocean.
- Baltic Sea: Produces similar effects in parts of northern and eastern Europe.
Effects of Lake-Effect Snowstorms
- Heavy Snowfall: Accumulations can exceed several feet in a short period of time.
- Spatial Intensity: Snowfall is concentrated in narrow bands, creating sharp contrasts in accumulation in small areas.
- Travel Obstacles: Reduced visibility, snow-covered roads, and frequent accidents.
- Economic Impact: Business disruptions, school closures, and snow removal costs.
Famous Lake-Effect Snow Events
- Buffalo, New York (2014): A historic lake-effect storm dumped more than 7 feet of snow in some areas, stranding residents and closing roads.
- Erie, PA (2017): A Christmas storm brought more than 5 feet of snow in just two days.
- Snow November (2014): Buffalo experienced more than 6 feet of snow in some locations in 48 hours.
Preparedness Tips
- Monitor Weather Reports: Watch for lake-effect snow warnings.
- Stock up on supplies: Have food, water, and essential items ready for possible isolation.
- Travel safely: Avoid unnecessary travel. If driving, carry emergency supplies.
- Snow removal: Be prepared to shovel or plow frequently.
Lake-effect blizzards can be beautiful but very disruptive, reflecting the power of local weather phenomena influenced by geography and atmospheric conditions.
Summary of Snowstorm
Formation
Snowstorm occur when there is cold air near the earth's surface and moisture in the warm air condenses and freezes.
Key factors include:
- Temperature: Below freezing at both the surface and at altitude.
- Humidity: Abundant moisture in the atmosphere for cloud and snow formation.
- Lift: Mechanisms such as weather fronts or topography that push air upward, cooling it and producing snow.
Effects
- Transportation: Snow-covered roads, low visibility, and icy conditions cause travel disruptions.
- Infrastructure: Snow accumulation can damage power lines and structures.
- Daily life: School closures, flight cancellations, and business disruptions.
- Safety risks: Hypothermia, frostbite, and accidents due to icy surfaces.
Safety tips
- Stay indoors during a severe storm.
- Have emergency supplies including food, water, blankets, and flashlights.
- Drive carefully if necessary and carry an emergency kit.
- Dress warmly in layers to avoid frostbite and hypothermia.
