Q. With reference to the polar vortex, consider the following statements:
The polar vortex is a vast zone of low pressure that swirls around the Earth's poles.
Sudden stratospheric warming can cause the polar vortex to collapse, allowing Arctic air to surge southward.
The polar vortex extends from the tropopause through the stratosphere and into the mesosphere.
Select the correct option from the codes given below: Answer:
All three
Notes:
The polar vortex is a vast zone of low pressure that swirls around the Earth's poles. Correct: It is an atmospheric feature that influences winter weather patterns by containing frigid air around the poles.
Sudden stratospheric warming can cause the polar vortex to collapse, allowing Arctic air to surge southward. Correct: This phenomenon leads to a rapid temperature increase in the stratosphere, disrupting the polar vortex and allowing cold Arctic air to move southward, resulting in extreme weather conditions.
The polar vortex extends from the tropopause through the stratosphere and into the mesosphere. Correct: The polar vortex extends from the tropopause (the dividing line between the stratosphere and troposphere) through the stratosphere and into the mesosphere (above 50 km).
