Q.3 Consider the following statements regarding Polar Vortex:

i. Polar vortex a large pocket of very cold air typically near the North Pole.

ii. The weakening of the polar jet stream can lead to a breakdown of the polar vortex allowing the frigid air of Polar Vortex to spill southward into the areas like southern Canada and the United States.

iii. An exceptionally strong ridge build over Alaska can stretch well far north into the territories that house the polar vortex and displace the arctic frigid air southward into the areas like southern Canada and the United States.

Which of the above statement/s is/are correct?

a. i and ii

d. i, ii and iii

Ans: d

Q.4. Why did the ozone hole develop over Antarctica and not in other parts?

A. In winter, the stratosphere above the Antarctic continent gets colder than it does anywhere else on Earth. Lower temperatures favor the formation of polar stratospheric clouds (PSCs) which serve as platforms for catalytic ozone breakdown.

B. The circulation over the Antarctic is more persistent and vortex-like as a consequence of having less land. Air inside the vortex is prevented from mixing with warmer, ozone-rich air from lower latitudes.

Correct option is:

a. Only A is correct

b. Only B is correct

c. Both A and B are correct

d. None is correct

Ans: c

Q.5. Consider the following statements:

i. Western Disturbance is an extratropical storm that brings sudden winter rain and snow to the northwestern parts of the Indian subcontinent.

ii. Western Disturbance is a monsoonal precipitation pattern driven by the Westerlies.

iii. The moisture in Western Disturbance usually originates over the Mediterranean Sea and the Atlantic Ocean.

iv. Extratropical storms like Western Disturbance are a global, rather than a localized, phenomena.

v. Moisture usually carried in the lower atmosphere in Extratropical storms unlike tropical storms where it is carried in the upper atmosphere.

Which of the above statement/s is/are incorrect?

b. iii and v

c. iv and v

d. ii and v

Ans:  d

Western Disturbance is a non-monsoonal precipitation pattern.

Q.8 A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers. Consider the following statements:

i. It indicates that global climate change is not occurring.

ii. The increase in ice mass is the result of increased precipitation, which is the result of increased atmospheric water vapor, which is the result of increased global temperatures.
