How jet streams affect the climate of india
Jet streams are fast-flowing, narrow air currents found at high altitudes in the Earth's atmosphere. These currents, which typically occur at an altitude of around 7-12 kilometers, are formed by the difference in temperature between the polar and tropical regions of the Earth. The Earth's rotation also plays a role in the formation of jet streams, as it causes the air to move faster at the equator and slower towards the poles.
In India, the jet stream has a significant impact on the country's climate. The jet stream that affects India is known as the subtropical westerly jet stream, which is located at an altitude of around 9-12 kilometers. This jet stream moves from west to east and is responsible for bringing moist air from the Indian Ocean to the landmass of India.
During the winter months, the subtropical westerly jet stream moves further south, bringing cold and dry air from central Asia to India. This results in lower temperatures and dry conditions in the northern and central parts of the country. The northern states of India, such as Jammu and Kashmir, Punjab, and Haryana, experience cold and dry winters as a result of this jet stream.
On the other hand, during the summer months, the subtropical westerly jet stream moves further north, bringing moist and warm air from the Indian Ocean to India. This results in higher temperatures and increased rainfall in the northern and central parts of the country. The northern states of India, such as Uttar Pradesh and Bihar, experience hot and humid summers as a result of this jet stream.
In addition to affecting the temperature and precipitation patterns in India, the jet stream also plays a role in the formation of severe weather events, such as cyclones and thunderstorms. These weather events can cause significant damage and disruption in India, particularly in coastal areas.
Overall, the jet stream has a significant impact on the climate of India, affecting temperature and precipitation patterns as well as the formation of severe weather events. Understanding and predicting the movement of the jet stream is therefore important for predicting and mitigating the effects of these weather patterns on the country.
What are Jet streams and how they affect climate of India?
There also lies a high pressure over the region of Tibet. The easterlies are very active in the upper layer of the atmosphere while the westerlies remain at the lower layer. Jet streams are the air currents found in the highest part of the atmosphere. Since the peak of the jet stream lies over north-western India, it creates a high pressure over that region. Be that as it may, assuming that a climate framework is far away from a fly stream, it could remain in one spot, causing heat waves or floods. This further creates a divergence in the wind patterns, which blocks the monsoon winds to flow.
Mechanism of Indian Monsoon and The Jet Stream Theory
They generally are located near the altitude of the tropopause and are westerly winds flowing west to east due to the Coriolis Effect movements of water and air currents induced due to the rotation of the earth. This creates anticyclonic conditions. The jetstream affects the Indian climate by increasing the average nighttime temperature signals, an impending approach to cyclone disturbances. They affect the Indian climate in the following ways. The winds that leave the jet streams divulge rapidly. This happens because of intense heating in the ground areas during the months of April, May, and June. The sub-tropical westerly jet stream blowing south of the Himalayas are responsible for the western cyclonic disturbances experienced in the north and north-western parts of the country during the winter months.
How do jet streams affect the Indian climate? Answer at BYJUâ€™S IAS
Besides giving the explanation of How the jet streams affect the climate of India, a detailed solution for How the jet streams affect the climate of India has been provided alongside types of How the jet streams affect the climate of India theory, EduRev gives you an ample number of questions to practice How the jet streams affect the climate of India tests, examples and also practice Class 9 tests. The south west monsoon in India is directly related to the tropical easterly stream. Jet streams are a narrow belt of high altitude above 12,000 m westerly winds in the troposphere. Apart from catering students preparing for JEE Mains and NEET, PW also provides study material for each state board like Uttar Pradesh, Bihar, and others. As the warmed air grows because of warming it becomes lighter than the surrounding air; in this way, it rises and makes a warm air current. The latter play a significant role in the distribution of rainfall in the country.

What Makes Us Different Physics Wallah strives to develop a comprehensive pedagogical structure for students, where they get a state-of-the-art learning experience with study material and resources. The high-pressure area below the peak is said to create anticyclonic conditions. The most constant are the mid-latitude and the sub tropical jet stream. These are either land to land winds or land to ocean winds. A number of separate jet streams have been identified. The intensity of monsoon rainfall: The arrival of tropical easterly jet streams influences the intensity of southwest monsoon.
How do jet streams affect the Indian climate?
As the warmed air expands due to heating it becomes lighter than the surrounding air; thus, it rises and creates a warm air current. As soon as the easterly emerges, the upper sir circulations take a reverse pattern. This further creates a diverging wind condition on the surface of the Earth. The western cyclonic disturbances experienced in the north and northwestern parts of the country are brought in by this westerly flow. Water currents have the ability to cool and warm the air, while air currents push air from one climate to another, bringing heat or cold and moisture with it. This beats up the air a piece like changes in a stream, so choppiness is another, frequently unwanted part of air travel. The highest rainfall happens along the track of these depressions.
How do jetstreams affect the climate of India?
The jet streams impact the onset of monsoon which depends upon the upper air circulation dominated by SubTropical Jet Streams STJ. They are the quick streaming, narrow, and wandering air currents and flows in the An air current is a streaming development of air inside a bigger collection of air; they flow in the layers of air surrounding the Earth. The cyclonic rotation, which creates a depression, is caused by the Coriolis effect. Answer : Jet streams are a narrow belt of high altitude above 12000 m westerly winds in the troposphere. The sub-tropical easterly jet stream blowing over peninsular How do jet streams and ocean currents affect local weather? India has a monsoon type of climate. They have the following effects on the Indian climate. They are shaped because of the uneven heating of the Earth by the sun.
How do Jet streams affect the climate of India
These disturbances also result in the creation of winter rain as well as heat storms in the north-western plains and snowfalls in the hilly regions. This creates a condition wherein the surrounding winds rush inwards. Final answer: Hence, the freezing, fast-moving winds formed in the atmosphere's upper layers are referred to as the Jet streams, and they form depressions and influence the rainfall in India. Also, the southern branch of the westerly which actively plays a role in activating the monsoon remains towards the south of the Himalayas. Cooler and heavier air then steps in to replace the emerged warm air in this way shaping a cool air current. This creates no rainfall.
