Your question: How do jet streams influence the climate of India Class 10 ICSE?

(i) Jet streams are cold fast blowing winds that develop in the upper layers of the atmosphere. (ii) They influence the climate of India as the westerly jet stream prevails over the North Indian Plains during the winter months, while the easterly jet stream steers the tropical depression over India.

How does the jet stream influence the climate of India?

Jet streams are the narrow belt of high altitude westerly winds in the troposphere. They blow at a fast speed of about 110km/h in summers to about 184km/h in winters. The westerly jet streams are responsible for bringing western cyclonic disturbances to north west India resulting in rainfall in winters.

How do the jet streams influence the climate of a place?

Jets streams play a key role in determining the weather because they usually separate colder air and warmer air. Jet streams generally push air masses around, moving weather systems to new areas and even causing them to stall if they have moved too far away.

How does El Nino affect the climate of India Class 10 ICSE?

El-Nino increases the surface temperature of the sea and affects the movement of monsoon winds in the Indian Ocean and causes weak drought-like situation in the Indian sub continent.

How jet streams affect the climate of India UPSC?

Climatic Significance of Jet Stream

Plays a significant role in the onset and withdrawal of monsoon winds. Known to have brought some ozone depleting substances to stratosphere which result in ozone layer depletion.

How do they influence the climate of India?

Latitude, attitude, pressure and winds are factors that influence the India’s climate. The Tropic of Cancer passes through the middle of the country from the Rann of Kuchchh in the west to Mizoram in the east. … These winds originate from the subtropical high-pressure belt of the northern hemisphere.

What are jet streams ICSE?

Jet streams are winds that blow horizontally from west to east at a high speed near the tropopause and the stratosphere. These are high speed winds which influence the weather and climatic conditions of the region over which they blow.

What are jet streams 9 geography?

Jet Streams are a narrow belt of high altitude (above 12,000 m) westerly winds in the troposphere. Their speed varies from about 110 km/h in summer to about 184 km/h in winter. A number of separate jet streams have been identified.

What happens to jet streams as they get closer to the equator?

They have warm, dry air. What happens to jet streams as they get closer to the equator? They blow faster. … Cold fronts form between two air masses that barely move, while stationary fronts form when a warm air mass is trapped between two cold air masses.

Why does jet stream move from west to east?

The jet stream is a narrow band of fast, flowing air currents located near the altitude of the tropopause that flow from west to east. … Jet streams carry weather systems. Warmer tropical air blows toward the colder northern air. These winds shift west to east due to the rotation of the earth.

How El Nino affect the climate of India?

In a phenomenon called El Nino, warming of sea surface temperatures in eastern equatorial Pacific, near the Peru coast — or the cooling effect in the same region called La Nina — affects the Indian southwest monsoon negatively or positively.

What is El Nino impact on Indian Climate Class 9?

El Nino refers to the large-scale ocean-atmosphere climate interaction linked to periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific. … El Nino adversely impacts the Indian monsoons and hence, agriculture in India.

What is the effect of El Nino on India’s climate Class 9?

El Nino – Effects on India

The Indian Ocean is warmer than the adjoining oceans and so, has relatively lower pressure. Hence, moisture-laden winds move from near the western Pacific to the Indian Ocean.

Where do jet streams flow in India?

Seasonal Migration of Sub-Tropical Jet Stream – STJ

In winter STJ flows along the southern slopes of the Himalayas but in summer it shifts northwards, rather dramatically, and flows along the northern edge of Himalayas in early June and in late summer (July-August) along the northern edge of the Tibetan Plateau.

Are jet streams westerly winds?

Jet streams are fast flowing, narrow bands of wind in the upper atmosphere that circle their way around the globe. … They are predominantly westerly winds due to the rotation and relative movement of the Earth, however due to their meandering path, they sometimes veer north or south.

What causes jet streams?

Jet streams form when warm air masses meet cold air masses in the atmosphere. The Sun doesn’t heat the whole Earth evenly. That’s why areas near the equator are hot and areas near the poles are cold. … A jet stream is a type of air current that forms high in the atmosphere.
