Winds MCQ Quiz - Objective Question with Answer for Winds - Download Free PDF

The correct answer is Option 1

Key Points

• BWh (Hot low latitude desert): This climate type is found in regions with minimal rainfall, high temperatures, and low humidity. These areas include deserts like the Sahara and Arabian Desert.
• BWk (Cold low latitude desert): This represents deserts in regions with colder temperatures, such as those in higher altitudes or areas with extreme continentality.
• BSh (Hot mid-latitude steppe): These areas are semi-arid regions with hot summers and relatively mild winters, often bordering deserts.
• BSk (Cold mid-latitude steppe): These climates are characterized by semi-arid conditions with colder winters, such as parts of Central Asia and the Great Plains of the USA.

Important Points

• Koppen's classification: Developed by Wladimir Koppen, this system categorizes world climates based on temperature and precipitation patterns.
• Desert (BW) climates: These areas are characterized by extremely low precipitation levels, making them arid and inhospitable for most vegetation.
• Steppe (BS) climates: Bordering desert regions, steppe climates receive slightly more precipitation, allowing for grasslands and sparse vegetation.
• Latitude impact: Latitude plays a critical role in determining whether a region's climate is "hot" or "cold." Lower latitudes near the equator are typically warmer, while higher latitudes are cooler.

The correct answer is Samoo → America.

Key Points

• Samoo is not a recognized wind system in America or any other region.
• It is likely a misrepresentation or misspelling of a name, as it does not correspond to any prominent geographical or meteorological terminology.
• Other winds mentioned in the question are well-documented and associated with specific regions.
• This makes "Samoo → America" the only incorrect match among the options.

Important Points

• The naming of winds is often based on the region where they occur or the effect they produce.
• For example, Khamsin, Bora, and Mistral are all winds with distinct characteristics and geographical associations.
• Incorrectly matched names may arise from typographical errors or a lack of proper documentation.

Additional Information

• Khamsin
  • ​A hot, dry, and dusty wind that occurs in North Africa and the Arabian Peninsula, particularly in Egypt, usually during the spring.
  • It is associated with desert regions and can bring discomfort due to its high temperatures and dust content.
• Bora
  • ​ A cold, dry, and strong wind blowing from the northeast along the Adriatic coast, especially in countries like Croatia and Italy.
  • It typically occurs in winter and is caused by the pressure difference between the mountains and the sea.
• Mistral
  • A strong, cold, and dry wind that blows from the north or northwest through the Rhône Valley in France and into the Mediterranean.
  • It is known for its high speeds and effects on the climate and vegetation of southern France.

    • These showers are useful for tea, jute and rice cultivation. In Assam, these storms are known as Bardoli Chheerha.
• Loo: Hot, dry and oppressing winds blowing in the Northern plains from Punjab to Bihar with higher intensity between Delhi and Patna.

The correct answer is Loo.

Key Points

• Loo:
  • Loo is a type of local wind that blows in some regions of India and Pakistan.
  • Harmful Wind
  • In the plains of northern India and Pakistan, sometimes a very hot and dry wind blows from the west in the months of May and June, usually in the afternoons.
  • It is known as its temperature invariably ranges between 45°C and 50°C. It may cause sunstroke to people.

Additional Information

• The movement of air from high-pressure to low-pressure areas is called wind.
• Winds are broadly classified into three types:
  • Permanent Winds
  • Seasonal Winds
  • Local Winds
• Local Winds are winds that blow only during a particular period of the day or year in a small area.
• Some of the local winds with the area of flow are:
  • Chinook- Rockies
  • Foehn- Alps
  • Loo- Gangetic plain, North India and Pakistan
  • Sirocco- Sahara
  • Mistral- Spain
  • Blizzard- Polar regions of Canada and the USA

The correct answer is Loo - Hot wind.

Key Points

• The Loo is a strong, dusty, gusty, hot, and dry summer wind from the west which blows over the western Indo-Gangetic Plain region of North India and Pakistan.
• Loo winds originate over the Iranian, Baloch, and Thar deserts.
• It is especially strong in the months of May and June.
• Due to its very high temperatures (45 °C–50 °C or 115 °F–120 °F), exposure to it often leads to fatal heatstrokes.
• Since it causes extremely low humidity and high temperatures, the Loo also has a severe drying effect on vegetation leading to widespread browning in the areas affected by it during the months of May and June.
• In tropical regions particularly in northern India during the summer season, local winds called 'loo' are the outcome of the advection process.
• Winds are a result of advection, while air currents are a result of convection.

Additional Information

• Kaal Baisakhi:
  • ​It is a local rainfall and thunderstorm that occurs in Assam and West Bengal and in India or Bangladesh.
    • It occurs in the summer season.
  • It harms life and money and generally occurs in the month of Baisakh (April-May), hence it is known as 'Kaal Baisakhi'.
  • It originated from Chota Nagpur Plateau.
  • Since It is caused by winds coming from the northwest direction, they are also called 'northwestern'.
• Trade winds:
  • ​Trade winds ate winds that blow westward and towards the Equator from the sub-tropical high-pressure belts towards the Intertropical Convergence Zone (ITCZ).
  • They blow from the subtropical high-pressure zone to the equatorial low-pressure zone.
  • They can be found about 30 degrees north and south of the equator.
  • Around 30 degrees in both hemispheres, air begins to descend towards the surface in sub-tropical high-pressure belts known as subtropical ridges.

The correct answer is Option 1.

Key Points

• Norwesters or the Kalbaishakhi is a local rainfall and thunderstorm which occurs in India and Bangladesh.
• The direction of squalls is mainly from the northwest and they are called Norwesters (Squall – a sudden, violent gusty wind).
• Kalbaishakhi occurs with increasing frequency from March till monsoon establishes over North-East India.
• Kal Baisakhi originates in the Chhotanagpur Plateau, in and around the cities of Ranchi and Jamshedpur.
• In times of incursion of moist air in these elevated regions, amidst high temperatures, these extremely destructive thunderstorms occur.
• These rainfall storms are beneficial for the cultivation of tea in Assam and for the jute and rice and tea cultivated in West Bengal and Bangladesh
• The first sign of Norwester is a low bank of a dark cloud in the northwest region, the upper outline of which has the appearance of an arch.
•  It approaches slowly at first and then rapidly with a strong gust or squall.

The climate of India is described as the ‘monsoon’ type. There are six major controls of the climate of any place. They are latitude, altitude, pressure and wind system, distance from the sea (continentality), ocean currents, and relief features.

Pressure and Winds:

• The climate and associated weather conditions in India are governed by the following atmospheric conditions:
  • Pressure and surface winds;
  • Upper air circulation; and
  • Western cyclonic disturbances and tropical cyclones.
• India lies in the region of northeasterly winds.
• These winds originate from the subtropical high-pressure belt of the northern hemisphere.
• They blow south, get deflected to the right due to the Coriolis force, and move on towards the equatorial low-pressure area.
• Generally, these winds carry very little moisture as they originate and blow over land.
• Therefore, they bring little or no rain

Hence, option 1 is the correct answer.

Westerlies: 

• The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east.
• They are generally found in the middle latitudes between 30 and 60 degrees latitude.
• They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner.

Periodic wind: 

• Periodic winds blow at regular intervals or in regular cycles.
• They are winds that result from localized differences in pressure and temperature.
• For example, land and sea breezes and the seasonal winds.

Local wind:

• Local winds are winds that blow over a limited area. 
• Local winds blow between small low and high-pressure systems.
• They are influenced by local geography. 
• For example, Loo, chinook, blizzard, etc.

The correct answer is option 3 i.e. South-West Monsoon.

• Air moves from the high-pressure area over the southern Indian Ocean in a south-easterly direction and turns right towards low-pressure areas over the Indian subcontinent. These we know as the South-West Monsoon winds.
• South-West monsoon is the rain-bearing seasonal winds that flow from the Arabian Sea to the mainland of India.
• Southwest monsoon winds are referred to as "Indian Summer Monsoon".
• Coriolis effect is responsible for affecting the direction of the wind.
• The force which is exerted by the rotation of the earth is called as Coriolis Force
• The trade winds are also known as Easterlies.
• The trade winds blow from sub-tropical high-pressure areas (30N and S) towards the equatorial low-pressure belt.
• Westerly winds blow from sub-tropical high-pressure belts towards the low-pressure belts.
• Westerly winds develop between 40-65N latitudes.
