Which is a component of upper air circulation?

(a) Jet Streams

(b) Volcano

(c) Cyclone

(d) Hurricane

 

Answer:

So, the correct option is (a) Jet Streams 

Explanation

  • (a)Jet Stream is a narrow belt of high altitude (above 12,000 m) westerly winds in the troposphere and it flows at a higher altitude of the atmosphere. Thus, it has upper air circulation.

  • (b) Volcanoes do not have air circulation but pyroclastic flow occurs at the time of eruption that moves at speeds as high as 200 m/s.

  • (c) Cyclones formed rapid inward air circulation around the low-pressure area.

  • (d) Hurricane formed closed inward air circulation around the low-pressure area.
