      Jet streams are fast flowing winds moving in the upper air of the atmosphere.
      (i) Sub-tropical Westerly Jet Streams: These jet streams are located
      approximately over 27′-30′ north latitude; therefore, they are known
      as sub-tropical westerly jet streams. over India, these jet streams blow
      south of the Himalayas all through the year except in summer. During
      winters, the cyclonic disturbances are brought into India by these jet
      streams.
      (ii) Tropical-easterly Jet Streams: These easterly jet streams blow over
      peninsular India, approximately over l4’N, during the summer months.
      it is believed to be responsible for the sudden outbreak of the south-west
      monsoon in India.
