What are jet streams explain their influence on the climate of India in summers and winters?
Jet streams affect the climate of India. They help in bringing the Western Disturbances to north and north-western parts of India. Western Disturbances cause much needed winter rains over the north and north-westem parts of India and snowfall in the mountains.
What are jet streams describe their influence on the climate of India?
(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.
What are jet streams Class 9 short answer?
Answer: 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. … The most constant is the mid-latitude and subtropical jet stream.
What is jet stream Class 9?
Jet streams are fast flowing narrow meandering air currents found in the atmosphere of some planets including earth. The westerly flows are responsible for the western disturbances experienced in the north and north western parts of the country.
How do jet streams affect the climate?
Shifting jet stream patterns can have a big impact on the weather. … Air north of a jet stream is typically colder, while air to the south is usually warmer. As jet streams dip or break off, they move air masses around, creating shifts in global weather patterns.
What is Jet Stream Class 10?
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.
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.
How jet stream affect the climate of a place Class 9?
In summer the western jet streams shift to the north of the Himalayas creating a low pressure region over Indian Peninsula which forces the monsoon (moisture laden) winds from the south to cause rainfall. The tropical jet stream blows over the Indian Peninsula; approximately over 14° north during the summer months.
What is jet stream Class 11?
What is a jet stream? A very strong and steady westerly wind blowing just below the tropopause. … (iii)Difference in air pressure causes reversal in the direction of monsoon winds.
