Best answer: What is the jet stream and why is it important to our weather?

What is the jet stream and how does it work?

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air.

What are jet streams Class 9?

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 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.

What are jet streams how they affect the climate?

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.

What are jet streams and how do they affect the climate of India Class 9?

Jet streams are the air currents found in the highest part of the atmosphere. 1. The jet streams impact the onset of monsoon which depends upon the upper air circulation dominated by SubTropical Jet Streams (STJ). The south west monsoon in India is directly related to the tropical easterly stream.

What are jet streams quizlet?

Jet streams are fast flowing, narrow air currents found in the upper atmosphere or in troposphere of some planets, including Earth. … The two jet streams that directly affect our weather in the continental US are the polar jet and the subtropical jet.

Why do jet streams flow 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.

What are jet streams how it influence the climate of India?

Answer. (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.
