The Big Blow
The Great Lakes Storm of 1913 (historically referred to as the "Big Blow", the "Freshwater Fury", and the "White Hurricane") was a blizzard with hurricane-force winds that devastated the Great Lakes Basin in the Midwestern United States and Southwestern Ontario, Canada, from November 7 to 10, 1913. The storm was most powerful on November 9, battering and overturning ships on four of the five Great Lakes, particularly Lake Huron. The storm was the deadliest and most destructive natural disaster to hit the lakes in recorded history. More than 250 people were killed. Shipping was hard hit; 19 ships were destroyed, and 19 others were stranded. About $1 million of cargo weighing about 68,300 tons—including coal, iron ore, and grain—was lost. The storm impacted many cities including; Duluth, Minnesota - Chicago, Illinois and Cleveland, Ohio which received of snow combined with winds up to and was paralyzed for days. The extratropical cyclone originated when two major s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
November Gale
November gale, the Witch of November, or November Witch, refers to the strong winds that frequently blow across the Great Lakes in autumn. The "witches" are caused by intense low atmospheric pressure over the Great Lakes pulling cold Canadian/Arctic air from the north or northwest and warm Gulf air from the south. When these cold and warm air masses collide, they can result in hurricane force winds that stir up large waves on the lakes. Gordon Lightfoot's song " The Wreck of the ''Edmund Fitzgerald''''"'' makes reference to the Witch of November: the storm that wrecked the ''Edmund Fitzgerald'' was 978 mbar, equivalent to a borderline Category 1/2 hurricane. Similar witches have caused numerous shipwrecks over the years. Another storm that hit in November 1998 was 967 mbar, equivalent to a solid Category 2 hurricane. A still stronger storm, of October 2010, brought Minnesota and Wisconsin record low barometric pressures of, respectively, 954.96 and 961.06 mbar (both equivalent t ...

Wind Gust
A gust or wind gust is a brief increase in the speed of the wind, usually less than 20 seconds. It is of a more transient character than a squall, which lasts minutes, and is followed by a lull or slackening in the wind speed. Generally, winds are least gusty over large water surfaces and most gusty over rough land and near high buildings. Definition The wind is measured using an anemometer or estimated with a windsock. The average value of wind speed is generally measured over a period of 2 minutes before the meteorological observation according to the World Meteorological Organization. Any significant variation at this mean wind during the ten minutes preceding the observation are noted as gusts in messages such as METAR. It is generally reported in METAR when the peak wind speed reaches at least 16 knots and the variation in wind speed between the peaks and average wind is at least 9 to 10 knots. In marine meteorology, the top speed of a burst is expressed in meters per second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formation and ...

Colorado Low
A Colorado low is a low-pressure area that forms in southeastern Colorado or northeastern New Mexico, typically in the winter. After forming, the system moves across the Great Plains. Colorado lows can produce heavy wintry precipitation, and have a general east to northeast movement, impacting regions as far north as Winnipeg and as far east as the Atlantic coast. If upper-level conditions are right, the jet stream can push the low farther south, bringing wintry precipitation as far as Texas. When pushed this far south, the system is often referred to as a " blue norther". On the more typical track, a Colorado low can be similar to an Alberta clipper. In the winter Colorado lows are responsible for a majority of the snow that the Midwest receives; however, summer systems can trigger long-lasting convective systems, including severe weather. Spring and early summer Colorado low cyclogenesis can result in significant tornado outbreaks over the Great Plains and Midwest. See also * Den ...

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...

Leeward
Windward () and leeward () are terms used to describe the direction of the wind. Windward is ''upwind'' from the point of reference, i.e. towards the direction from which the wind is coming; leeward is ''downwind'' from the point of reference, i.e. along the direction towards which the wind is going. The side of a ship that is towards the leeward is its "lee side". If the vessel is heeling under the pressure of crosswind, the lee side will be the "lower side". During the Age of Sail, the term ''weather'' was used as a synonym for ''windward'' in some contexts, as in the ''weather gage''. Because it captures rain, the windward side of a mountain tends to be wet compared to the leeward it blocks. Origin The term "lee" comes from the middle-low German word // meaning "where the sea is not exposed to the wind" or "mild". The terms Luv and Lee (engl. Windward and Leeward) have been in use since the 17th century. Usage Windward and leeward directions (and the points ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexico, Mexican States of Mexico, states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern United States, Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific Ocean, Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.

Alberta Clipper
An Alberta clipper, also known as an Alberta low, Alberta cyclone, Alberta lee cyclone, Canadian clipper, or simply clipper, is a fast-moving low-pressure system that originates in or near the Canadian province of Alberta just east of the Rocky Mountains and tracks east-southeastward across southern Canada and the northern United States to the North Atlantic Ocean. Alberta clippers constitute a major winter-season storm track for extratropical cyclones in the Northern Hemisphere, tracking across the continent in 2–3 days while affecting weather in parts of the Prairies and central provinces of Canada, as well as the Upper Midwest, Great Lakes, and New England portions of the United States. They are associated with cold, dry continental air masses and generate small-scale, short-lived weather events typically producing 8–15 cm (3-6 inches) of snow in a 3-6 hour period. However, they can precipitate sudden temperature drops and sharp winds leading to local blizzard c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wind Fetch
In oceanography wind fetch, also known as fetch length or simply fetch, is the length of water over which a given wind Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hou ... has blown without obstruction. Fetch is used in geography and meteorology and its effects are usually associated with sea state and when it reaches shore it is the main factor that creates storm surge which leads to coastal erosion and flooding. It also plays a large part in longshore drift. Fetch length, along with the wind speed (wind strength), and duration, determines the size (sea state) of ocean surface wave, waves produced. If the wind direction is constant, the longer the fetch and the greater the wind speed, the more wind energy is transferred to the water surface and the larger the resulting sea state wil ...
