The mistral is a strong, cold, northwesterly wind that blows from southern France into the Gulf of Lion in the northern Mediterranean. It produces sustained winds averaging 31 miles an hour, sometimes reaching 60 miles an hour. It can last for several days. Periods of the wind exceeding 30 km/h for more than sixty-five hours have been reported. It is most common in the winter and spring, and strongest in the transition between the two seasons.
A Foehn, or Föhn, is a type of dry, relatively warm downslope wind in the lee of a mountain range. It is a rain shadow wind that results from the subsequent adiabatic warming of air that has dropped most of its moisture on windward slopes. As a consequence of the different adiabatic lapse rates of moist and dry air, the air on the leeward slopes becomes warmer than equivalent elevations on the windward slopes.
Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation.
A rain shadow is an area of significantly reduced rainfall behind a mountainous region, on the side facing away from prevailing winds, known as its leeward side.
Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant. The smaller-scale weather systems – mid-latitude depressions, or tropical convective cells – occur chaotically, and long-range weather predictions of those cannot be made beyond ten days in practice, or a month in theory.
A sea breeze or onshore breeze is any wind that blows from a large body of water toward or onto a landmass. By contrast, a land breeze or offshore breeze is any wind that blows from a landmass toward or onto a large body of water. Sea breezes and land breezes are both important factors in coastal regions' prevailing winds.
Chinook winds, or simply Chinooks, are two types of prevailing warm, generally westerly winds in western North America: Coastal Chinooks and interior Chinooks. The coastal Chinooks are persistent seasonal, wet, southwesterly winds blowing in from the ocean. The interior Chinooks are occasional warm, dry föhn winds blowing down the eastern sides of interior mountain ranges. The coastal Chinooks were the original term, used along the northwest coast, and the term in the interior of North America is later and derives from the coastal term.
Avalon is a federal electoral district on Newfoundland Island in Newfoundland and Labrador, Canada. It has been represented in the House of Commons of Canada since 2004.
The trade winds or easterlies are permanent east-to-west prevailing winds that flow in the Earth's equatorial region. The trade winds blow mainly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, strengthening during the winter and when the Arctic oscillation is in its warm phase. Trade winds have been used by captains of sailing ships to cross the world's oceans for centuries. They enabled European colonization of the Americas, and trade routes to become established across the Atlantic Ocean and the Pacific Ocean.
In meteorology, prevailing wind in a region of the Earth's surface is a surface wind that blows predominantly from a particular direction. The dominant winds are the trends in direction of wind with the highest speed over a particular point on the Earth's surface at any given time. A region's prevailing and dominant winds are the result of global patterns of movement in the Earth's atmosphere. In general, winds are predominantly easterly at low latitudes globally. In the mid-latitudes, westerly winds are dominant, and their strength is largely determined by the polar cyclone. In areas where winds tend to be light, the sea breeze-land breeze cycle is the most important cause of the prevailing wind. In areas which have variable terrain, mountain and valley breezes dominate the wind pattern. Highly elevated surfaces can induce a thermal low, which then augments the environmental wind flow. Wind direction at any given time is influenced by synoptic-scale and mesoscale weather like pressure systems and fronts. Local wind direction can also be influenced by microscale features like buildings.
Barrie was a federal electoral district in Ontario, Canada that was represented in the House of Commons of Canada from 2004 to 2015. It consisted of the City of Barrie in the County of Simcoe. It was created in 2003 when its predecessor, Barrie—Simcoe—Bradford, was redistributed. Barrie—Simcoe—Bradford consisted of the City of Barrie and the towns of Bradford West Gwillimbury and Innisfil. It had been formed in 1996 as Barrie—Simcoe from Simcoe Centre and York—Simcoe ridings, but its name was changed before an election was held.
The nor'west arch is a band of high white lenticular cloud that forms on the eastern side of New Zealand's South Island and which looks like an arch in an otherwise clear blue sky over the Southern Alps. It is accompanied by a strong hot northwesterly or northerly wind known as a "nor'wester". In Canterbury, where it is a well known feature, it is also called the Canterbury arch. It also occurs in Otago and Marlborough and east of mountain ranges along the east coast of the North Island.
In physical geography and physical geology, aspect is the compass direction or azimuth that a terrain surface faces.
"Cape Doctor" is the local name for the strong, often persistent and dry south-easterly wind that blows on the South African coast from spring to late summer. It is known as the Cape Doctor because of a local belief that it clears Cape Town of pollution and 'pestilence'.
The Marin is a warm, moist wind in the Gulf of Lion of France, blowing from the southeast or south-southeast onto the coast of Languedoc and Roussillon. It brings rain to this region which it has picked up crossing the Mediterranean, and also can bring coastal fog. The clouds carried by the Marin frequently cause rain on the slopes of the mountains in the interior, the Corbières Massif, Montagne Noire, and the Cévennes. The wind is usually dried by the föhn effect when it crosses the mountains and descends on the other side. The Marin wind contributes to the creation of another regional wind, the autan (wind). The Marin blows gently from the offshore coast of the Mediterranean towards the Cévennes and the Montagne Noire. When this occurs it creates fine weather for swimming in the gulf, but when the wind is strong it creates heavy swells which strike the coast with high breaking waves.
Berg wind is the South African name for a katabatic wind: a hot dry wind blowing down the Great Escarpment from the high central plateau to the coast.
The Chittenden-3-2 Representative District is a one-member state Representative district in the U.S. state of Vermont. It is one of the 108 one or two member districts into which the state was divided by the redistricting and reapportionment plan developed by the Vermont General Assembly following the 2000 U.S. Census. The plan applies to legislatures elected in 2002, 2004, 2006, 2008, and 2010. A new plan will be developed in 2012 following the 2010 U.S. Census.
The levant is an easterly wind that blows in the western Mediterranean Sea and southern France, an example of mountain-gap wind. In Roussillon it is called "llevant" and in Corsica "levante". In the western Mediterranean, particularly when the wind blows through the Strait of Gibraltar, it is called the Viento de Levante or the Levanter. It is also known as the Solano.
The southeast Australian foehn is a westerly foehn wind and a rain shadow effect that usually occurs on the coastal plain of southern New South Wales, and as well as in southeastern Victoria and eastern Tasmania, on the leeward side of the Great Dividing Range.
The Australian High, also known as the Australian subtropical ridge, is a large, semi-permanent high pressure area or subtropical anticyclone that seasonally vacillates between the Great Australian Bight in the south to the Northern Territory in the north. It is generally located between 25 and 40 degrees of south latitude, depending on the season.
