What are the factors that affect the mechanism of Indian monsoon?
1) The differntiated heating and cooling of land and water creates low pressure on the landmass of India while the seas around experiences comparitively high prrssure. 2) The position of Inter Tropical Convergence zone (ITCZ) in summer shift over the ganga plains.
What are the factors affecting 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 factors affecting Indian monsoon Class 9?
The presence of the high-pressure area, east of Madagascar, approximately at 20°S over the Indian Ocean affects the Indian Monsoon. The Tibetan plateau gets intensely heated during summer, which results in strong vertical air currents and the formation of low pressure over the plateau at about 9 km above sea level.
What are the three important factors which influence the mechanism of Indian weather?
The three important factors which influence the mechanism of Indian weather are: Distribution of air pressure and winds on the surface of the earth. Upper air circulation caused by factors controlling global weather and the inflow of different air masses and jet streams.
Which facts are important to understand the mechanism of monsoon of India?
To understand the mechanism of the monsoons, the following facts are important. … The shift of the position of Inter Tropical Convergence Zone (ITCZ) in summer, over the Ganga plain (this is the equatorial trough normally positioned about 5°N of the equator – also known as the monsoon trough during the monsoon season).
What are the mechanism of monsoon explain?
Mechanism of Monsoon involves the following concept: The phenomena of monsoon refer to the seasonal reversal of winds. It is because while the South West Monsoon winds blow from sea to land at the end of the summer season, the North east winds blow from land to sea during the winter season.
What is monsoon and its types?
A monsoon is a seasonal wind system that shifts its direction from summer to winter as the temperature differential changes between land and sea. Monsoons often bring torrential summer rains, such as on the Indian subcontinent where the summer monsoon delivers three-quarters of the country’s annual precipitation.
Why do monsoon breaks occur?
Explain the reasons why break in monsoon occurs – When tropical disturbances advance along the monsoon trough, sometimes the sea level low pressure area weakens and making the low pressure area from 900 mb to 700 mb height to move north of the trough. … This is how a monsoon break works.
What are the factors that affect Indian climate?
Factors Influencing Indian Climate
- Latitudinal location.
- Distance from the Sea.
- The Himalayas.
- Monsoon Winds.
- Upper Air Circulation.
- El Nino and La Nina.
- Tropical Cyclones and Western Disturbances.
What is pressure and surface winds Class 9?
Pressure and Winds: The Indian subcontinent lies in the region of north-easterly winds. These winds originate from the subtropical high-pressure belt of the northern hemisphere. After that, these winds blow towards south. … Cold winds from this region blow to the low pressure areas over the oceans in the south.
What is Itcz class 9th?
The Inter Tropical Convergence Zone, or ITCZ, is a belt of low pressure which circles the Earth generally near the equator where the trade winds of the Northern and Southern Hemispheres come together. It is characterised by convective activity which generates often vigorous thunderstorms over large areas.
