Where are Chinook Winds found?
While Chinooks can occur on the downward slope of any mountain in the world, including areas in Argentina and the Swiss Alps, in Canada they are most common in southern Alberta.
What causes a chinook wind?
Rapid rise Chinook winds develop when warm, moist air blows from the Pacific Ocean in the northwest region of North America toward the Rocky Mountain range, according to Rocky Mountain National Park. The air mass cools as it climbs the mountains, bringing rain or snow to the peaks.
What is Chinook in geography?
Chinook winds, or simply Chinooks, are a warm, dry wind that blows mostly in the winter along the eastern slopes of the Rocky Mountains. The Chinook is a type of local wind which is part of the Geography syllabus of the UPSC examination.
What is Foehn and Chinook?
Foehn winds are warm, dry downslope winds that occur on the lee side of topographic barriers. In southwestern Alberta, Canada, wind erosion is periodically associated with strong foehn winds that flow down the eastern flank of the Rocky Mountains, locally known as Chinooks.
Where do katabatic winds occur?
Katabatic winds are most commonly found blowing out from the large and elevated ice sheets of Antarctica and Greenland. The buildup of high density cold air over the ice sheets and the elevation of the ice sheets brings into play enormous gravitational energy.
What is a chinook wind quizlet?
-Chinook: Warm, dry, downslope wind that descends the eastern slope of the Rocky Mountains.
What is the hot wind called?
Sirocco. A sirocco is a hot desert wind that blows northward from the Sahara toward the Mediterranean coast of Europe. More broadly, it is used for any kind of hot, oppressive wind.
What type of wind is foehn?
foehn, German Föhn, warm and dry, gusty wind that periodically descends the leeward slopes of nearly all mountains and mountain ranges. The name was first applied to a wind of this kind that occurs in the Alps, where the phenomenon was first studied.
What is the Khamsin wind?
khamsin, also spelled Khamseen, or Chamsin, hot, dry, dusty wind in North Africa and the Arabian Peninsula that blows from the south or southeast in late winter and early spring.
What is a mountain wind called?
…of such winds, known as mountain winds or breezes, is induced by differential heating or cooling along mountain slopes. During the day, solar heating of the sunlit slopes causes the overlying air to move upslope. These winds are also called anabatic flow.
What is katabatic and Anabatic wind?
Anabatic Winds are upslope winds driven by warmer surface temperatures on a mountain slope than the surrounding air column. Katabatic winds are downslope winds created when the mountain surface is colder than the surrounding air and creates a down slope wind.
How is a chinook wind different from a katabatic wind?
How does a 'katabatic' wind differ from a 'chinook' wind? Even though both are descending winds, the 'katabatic' wind is called a cold down sloping wind vs the 'chinook' wind which is a warm down sloping wind. The difference occurs in the formation process.
What is a local wind quizlet?
local winds. –winds that blow over short distances. Ex: Sea breezes and land breezes.
What is wind called?
Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth's own rotation. Winds range from light breezes to natural hazards such as hurricanes and tornadoes.
How are winds named?
A wind is always named according to the direction from which it blows. For example, a wind blowing from west to east is a west wind. The ultimate cause of Earth's winds is solar energy.
Where is foehn wind?
1. The term foehn originated in the Alpine region of Austria, Switzerland and Southern Germany. However, winds that result from the same meteorological phenomena are present all over the world. Examples are Chinook (North America), Helm (United Kingdom), Puelche (Chile), Halny (Poland) or Zonda (Argentina).
Which wind blows in Egypt?
The correct answer is Egypt. 'Khamsin' wind is a local wind of Egypt. 'Khamsin' wind is a hot, and dry wind.
What is the nature of Mistral wind?
mistral, Italian maestrale, cold and dry strong wind in southern France that blows down from the north along the lower Rhône River valley toward the Mediterranean Sea.
Where are katabatic winds found?
Katabatic winds are most commonly found blowing out from the large and elevated ice sheets of Antarctica and Greenland. The buildup of high density cold air over the ice sheets and the elevation of the ice sheets brings into play enormous gravitational energy.
What are mountain winds called?
Downslope Winds occur when warm/dry air descends rapidly down a mountain side. These are common on the east side of the Rocky Mountains, called Chinook Winds. These winds can blow over 40 mph, and can occur in sudden gusts that are even stronger, which can make driving hazardous.
How does Anabatic wind flow?
Due to its limited heat capacity, the surface heats the air immediately above it by conduction. As the air warms, its volume increases, and hence density and pressure decreases. The air becomes relatively buoyant and rises up the orographic slope (orographic lift), resulting in the anabatic flow (or wind).
What is katabatic and anabatic wind?
Anabatic Winds are upslope winds driven by warmer surface temperatures on a mountain slope than the surrounding air column. Katabatic winds are downslope winds created when the mountain surface is colder than the surrounding air and creates a down slope wind.
What is a local wind?
Winds which are generated over a comparatively small area by local terrain and weather. They differ from those which would be appropriate to the general pressure pattern.
What causes wind quizlet?
Wind is caused by differences in air pressure. Differences in air pressure are due to unequal heating.
What is the southwest wind called?
The Southwest Monsoon winds are called 'Nairutya Maarut' in India. Click here to know about what is Monsoon? The reversal of winds start taking place over the Indian sub-continent during the summer season, when cold and dry continental northwesterly winds are replaced by warm and moist southwesterly winds.
What is the north wind called?
Aparctias, sometimes called the north wind instead of Boreas.
What is wind name?
Short bursts of high speed wind are termed gusts. Strong winds of intermediate duration (around one minute) are termed squalls. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, and hurricane.
What are Spanish winds called?
It's called a Sirocco in other parts of the Mediterranean area.
What is harmattan wind?
harmattan, cool dry wind that blows from the northeast or east in the western Sahara and is strongest in late fall and winter (late November to mid-March).
What is local name of wind?
