Lake effect snow is snow that is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water.

The lower layer of air, heated up by the lake water, picks up water vapor from the lake and rises up through the colder air above.

Blizzards although they can be bad don't cause as much damage as hurricanes do.

Snowstorms and blizzards occur in places such as in the upper Midwest and the Great Plains but occur in most areas of the country except for the Gulf Coast and the California coast.

Blizzards can also occur all over the world, even in the tropics where it is cold on high altitude mountaintops.

The 5 categories of a blizzard include Extreme, Crippling, Major, Significant, and Notable.

The three types of blizzards include vertical advection, horizontal advection, and thermal mechanical.

Most blizzards are as cold as 20 F degrees although the blizzard may have colder temperatures depending on where you live.

But during a blizzard you should expect the temperature to drop to at least 20 F.

Most blizzards last for around 3 hours although blizzards may sometimes last a bit longer.

In order for the snowstorm to be categorized as a blizzard, the snowstorm must last for at least three hours and produce a large amount of falling snow.

Blizzards also have winds measuring over (35 miles) per hour.

These winds cause a large volume of snow to blow around in the air and near the ground, decreasing visibility.

A Nor'easter is typically worse than a blizzard as Nor'easters usually have higher winds and can even be as high as hurricane force winds.

The difference between a nor'easter and a blizzard is the nor'easter typically produces more wind and blows the snow at near or at hurricane force winds while the blizzard does not get as high in wind speed and typically only blows around 35 mph to 45 mph.

Nor'easters can produce heavy snow and blizzards, rain and flooding, and huge crashing waves.

These waves can cause erosion to the beach and severe damage to nearby buildings and structures.

Nor'easters can also produce wind gusts that are even stronger than hurricane-force winds.

Blizzards are caused and 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.

A blizzard is considered worse than a snowstorm as blizzards can drift snow much higher and reduce visibility even more than a snowstorm.

With a blizzard you typically get more snowfall than with a snowstorm.

Snowstorms and winter storms are generally considered less severe due to the lack of high winds and low visibility, but they can still be dangerous, especially when driving or walking on slick surfaces.

Snowstorm is a compound word also called a compound noun.

Snowstorm is a noun and not a verb.

When writing snowstorm the correct way to write and spell snowstorm is as one word which is snowstorm.

A bad snowstorm is called a blizzard.

Blizzards are a severe snowstorm that occur with winds in excess of 35 mph and visibility of less than a 1/4 mile for more than 3 hours.

Blizzards can also occur after snowfall when high winds cause whiteouts (fallen snow blowing around) and snowdrifts (huge mountains of snow), which decrease visibility.

Snowstorms happen at night because the night air cools faster which then causes warm air to push up quicker which is call heavy updraft,

When this happens this can cause high winds and extreme weather at night.

The difference between snow and a snowstorm is that snow is just snow falling from the sky in small amounts or large amounts without wind.

A snowstorm is when snow falls with wind and heavy wind and the snowfall can occur in really large amounts and even drift and pile up.

A snowstorm is a storm in which snow falls heavily.

During a snowstorm is may or may not thunder as well.

There have been times where I live I've had it thunder during a snowstorm but most often the snowstorm occurs with just heavy snow and wind blowing.

A storm where precipitation falls as snow is called a snowstorm.

During the winter, most precipitation forms as snow within the clouds because temperatures at the top of the storm are cold enough to make snowflakes.

Apart from large amounts of snowfall, at least 2 inches (5 cm) of snow in places where snow is not typical is considered a snowstorm.

However, snowfall of more than 6 inches (15 cm) is disruptive and is considered a snowstorm or winter storm in other parts of the country.

Winter storms create a higher risk of car accidents, hypothermia, frostbite, carbon monoxide poisoning, and heart attacks from overexertion.

Winter storms including blizzards can bring extreme cold, freezing rain, snow, ice and high winds.

The winter storms can last a few hours or several days.

Snow storms are usually caused by rising moist air within an extratropical cyclone (low pressure area.

The cyclone forces a relatively warm, moist air mass up and over a cold air mass.

If the air near the surface is not sufficiently cold over a deep enough layer, the snow will fall as rain instead.

A winter storm is a combination of heavy snow, blowing snow and/or dangerous wind chills.

A winter storm is life-threatening.

Blizzards are dangerous winter storms that are a combination of blowing snow and wind resulting in very low visibilities.
