What are Jet Streams?

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 that influence the weather and climatic conditions of the region over which they blow.

  • There are two types of jet streams that blow at a tropical belt of 300 north latitudes—the westerly jet stream and the easterly jet stream.
  • A branch of the Westerly jet stream brings moderate to heavy rainfall followed by cold waves in the Indian subcontinent.
  • The Easterly jet stream also helps the monsoon winds to blow into the greater part of India and bring monsoon showers.
