The low-pressure land system attracts south-east trade winds but after crossing equator due to Coriolis force, winds turn right towards the low-pressure areas over the Indian subcontinent. These winds start blowing in a south-westerly direction and enter the Indian peninsula as the southwest monsoon.

Which of the following is related with the mechanism of monsoon over Indian subcontinent?

The low-pressure land system attracts south-east trade winds but after crossing equator due to Coriolis force, winds turn right towards the low-pressure areas over the Indian subcontinent. These winds start blowing in a south-westerly direction and enter the Indian peninsula as the southwest monsoon.

What is southwest monsoon winds?

South-west Monsoon: Winds that give maximum rainfall to India are south-west monsoon. These winds bring rains towards the end of the summer due to high pressure built in the Indian Ocean. These monsoon strikes Malabar Coast in the month of June and by November leaves the country.

What is Itcz explain the mechanism of Indian monsoon?

The location of ITCZ shifts north and south of equator with the change of season. In the summer season, the sun shines vertically over the Tropic of Cancer and the ITCZ shifts northwards. The front where the south-west monsoons meet the north-east trade winds is known as the Monsoon Front (ITCZ).

What are southwest monsoon winds Class 9?

The South West monsoon winds are known for their vagaries____. A low pressure zone is created over north India that attracts moist winds from the high pressure area in the south of Indian Ocean. These winds cause rainfall in most parts of India and are known as southwest monsoons.

What are the controls affecting the climate of a place?

Answer. The factors affecting the climate of a place are referred to as controls and are latitude, altitude, pressure and wind system, distance from the sea, ocean currents, and relief features. Altitude is another factor controlling the climate of a place. Altitude refers to the height a place above sea level.

Where does monsoon come from in India?

What can be Expected During the Monsoon in India. The southwest monsoon reaches the coast of the southern state of Kerala around June 1. It usually arrives in Mumbai approximately 10 days later, reaches Delhi by the end of June, and covers the rest of India by mid-July.

What are the factors that influence the mechanism of monsoon?

Mechanism of monsoon

  • Due to Sun, there is differential heating of land and water.
  • The Intertropical Convergence Zone or ITCZ shifts over Ganga plains during the Summer.
  • The high-pressure area, east of Madagascar affects the monsoon.

What are the major controls of the climate class 9?

Climatic Controls

  • Latitude. The amount of solar energy received varies according to latitude due to the curvature of the earth.
  • Altitude. The atmosphere becomes less dense and temperature decreases when we go to the higher altitude from the earth surface.
  • Pressure and wind system.
  • Distance from the sea.

What are the major controls of the climate?

Expert Answer:

  • Latitude. It depends on how close or how far it is to the equator. …
  • Ocean currents. Certain ocean currents have different temperatures. …
  • Wind and air masses. Heated ground causes air to rise which results in lower air pressure. …
  • Elevation. …
  • Relief. …
  • Nearness to water.

How are southwest monsoon winds formed?

IT has generally been held that the south-west monsoon owes its origin to the great difference of temperature which exists during the summer months between the heated land surface of India and the surrounding oceans, the general idea being that the warm air over the land rises, and damp air from the sea flows into …

How does latitude affect climate diagram?

1. Latitude or distance from the equator – Temperatures drop the further an area is from the equator due to the curvature of the earth. In areas closer to the poles, sunlight has a larger area of atmosphere to pass through and the sun is at a lower angle in the sky.

What are the main features of southwest monsoon winds?

The southwest monsoon brings rains towards the end of summer as the high pressure built in the Indian Ocean pushes the wind masses towards the low pressure formed on land. It’s the temperature variation between the sea and the landmass – sea air being cooler and land being warmer – that causes the action.

What is climate very short answer?

Climate means the usual condition of the temperature, humidity, atmospheric pressure, wind, rainfall, and other Meteorology|meteorological Weather|elements in an area of the Earth’s surface for a long time. In simple terms climate is the average condition for about thirty years.

What are the two types of monsoon winds?

The Monsoon winds are classified into southwest monsoon and Northeast Monsoon on the basis of the direction from where they blow.

What are the five factors that affect the mechanism of Indian monsoon?

Factors influencing onset of SW monsoons:

  • Intense low-pressure formation over the Tibetan Plateau.
  • Permanent high pressure cell in the South of the Indian Ocean.
  • Subtropical jet stream.
  • African Easterly jet (Tropical easterly jet)
  • Inter-Tropical Convergence Zone (ITCZ)

What are the three important factors which influence the mechanism of Indian weather class 9?

Following are the three main factors which influence the mechanism of Indian weather :

  • Surface distribution of pressure and winds.
  • Upper air circulation of Jet stream.
  • Inflow of western disturbances in winter and tropical depressions in summer. They create variation in the local weather conditions.

What are the three important factors which influence the mechanism of?

The three important factors which influence the mechanism of Indian weather are: (i)Surface, pressure and winds. (ii)Jet stream and upper air circulation.

How do Latitude affect the temperature and climate of the world?

As latitude increases, the sun shines more obliquely and provides less warming energy. The equator always faces the sun directly, so the climate is warm year-round, with the average day and night temperature hovering between 12.5 and 14.3 degrees Celsius (54.5 and 57.7 degrees Fahrenheit).

What is longitude Class 9?

Answer: A longitude is the angular distance of a place east or we§t of the Prime Meridian or 0° longitude. The lines of longitude are the great semi-circles joining North pole and South pole and are equal in length. These are 0° – 180°E and 0° – 180°W longitudes or total 360°.

Does Latitude Affect Climate?

Many factors influence the climate of a region. The most important factor is latitude because different latitudes receive different amounts of solar radiation. The maximum annual temperature of the Earth, showing a roughly gradual temperature gradient from the low to the high latitudes.

What are the six major controls of the climate of any place Class 9?

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. Due to the curvature of the earth, the amount of solar energy received varies according to latitude.

Why are cold deserts in India not affected by the monsoon?

Location. The cold deserts of India are located adjacent to the Himalaya Mountains. They are not affected by the Indian monsoons because they lie in the rain shadow of the Himalayas.
