How many blizzards occur in a year

However, very disruptive winter storms may not qualify as blizzards for example, those involving high snowfalls, but without one or more other defining characteristics. There are significant inter- and intra-annual variations in blizzard frequency and severity that make statistical analysis of past trends problematic. Detailed studies are limited.

Nonetheless, at least in North America, historical evidence points to a decline in the frequency and severity of blizzards on the Canadian prairies and a significant decline in the frequency of. An increase in the vigor of winter storms in a warmer atmosphere may result in more frequent severe blizzards.

On the other hand, there is evidence for the occurrence of stronger blizzards along Russia's Pacific coast.

It may be reasonable to assume that in a warmer world there would be fewer blizzards. However, the occurrence of a blizzard is dependent on a specific combination of physical and meteorological factors. A systematic variation in one or more of these, as influenced by future climate change for example, storm intensity, shifting storm paths, wind velocity , ambient temperature, the amount of snowfall, and the amount and condition of snow on the ground , may affect the number, intensity, and geographical distribution of blizzards.

An increase in the vigor of winter storms in a substantially warmer and energetic atmosphere may result in severe blizzard conditions becoming more frequent. As sunspot activity was low in the mids and the mids, as well as now, Coleman projects that fewer sunspots correlate with greater snow storms. Other scientists suggest that the blitz in snowstorms may be attributed to macro climate patterns in the ocean and the atmosphere.

Brad Anderson, a meteorologist from Lincoln, Neb. Coleman added that a substantial amount of additional research and investigation will be needed to figure the exact reasons for the rise in snow storms. More than blizzards have taken place in the continental US since According to Coleman, blizzards in recent years are occurring outside the traditional season of October to March.

These severe snowstorms have taken place in all months except September and August. The most recent snowstorm on the East Coast had largely subsided by Sunday afternoon. With 60 million people affected, many endured power outages, cancelled transportation, and at least 20 people died in related incidents. While New York, D. Already a subscriber? Monitor journalism changes lives because we open that too-small box that most people think they live in. We believe news can and should expand a sense of identity and possibility beyond narrow conventional expectations.

My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. If you were to come up with a punchline to a joke about the Monitor, that would probably be it.

But you know what? We change lives. We have a mission beyond circulation, we want to bridge divides. Investigating whether this increased blizzard trend can be linked to long-term trends in dominant weather patterns will be the subject of future research. North Dakota, parts of northern South Dakota and northwestern Minnesota have at least a 61 percent chance of at least one blizzard in a given year.

The study found four North Dakota counties — Barnes, Benson, Cass and Traill — have the highest probability, just over 76 percent. A total of blizzards were documented in Traill and Cass Counties.

The rest of Minnesota, much of Iowa, Nebraska, northwest Kansas, eastern Colorado, far eastern Wyoming and parts of eastern Montana have at least a one-in-three chance of a blizzard each year, carving out the rest of the Plains blizzard alley. In the East, the highest blizzard probabilities are found in eastern New England. Blizzards have been reported in all months except September and August, but most occur in December, January, February and March.

While big blizzards that hit the East Coast make the news, most occur in the sparsely populated northern Plains and upper Midwest, especially in the Dakotas and Minnesota. Facebook Twitter Email. Researcher: Number of blizzards doubled in past 20 years. Show Caption. Hide Caption.
