Correct Answer: B

Explanation:
Atmospheric rivers are long, narrow regions of the atmosphere that transport water vapor from one region to another. They are typically hundreds of kilometers wide and thousands of kilometers long.

When atmospheric rivers make landfall, they can contribute significantly to precipitation. This can lead to heavy rainfall, snowfall, or mixed precipitation, depending on the temperature of the air mass they encounter.
Events like the 2018 Kerala floods, the 2022 Pakistan floods, and the lower Mississippi River floods were indeed linked to atmospheric rivers. These events experienced extreme precipitation and flooding due to the impact of atmospheric rivers.
Therefore, the correct statements are the second and third ones. The first statement is incorrect because atmospheric rivers are actually long and narrow, not short and wide.

Statement 1 is incorrect.
A recent study published in the American Meteorological Society’s Journal of Hydrometeorology reveals that peninsular river basins in India, including Narmada, Mahanadi, and Godavari, face a higher likelihood of widespread flooding compared to transboundary rivers like Ganga and Brahmaputra.
Drivers of widespread flooding are associated with atmospheric rivers, large atmospheric circulations carrying moisture from the tropics to extratropic. Events like the 2018 Kerala floods, the 2022 Pakistan floods, and the lower Mississippi River floods in 2008, 2011, and 2015–19 were linked to atmospheric rivers.
What are Atmospheric rivers?
They are long, narrow regions of the atmosphere that transport water vapour from the tropics to the poles. They can be 250–375 miles wide and over 1,000 miles long. When atmospheric rivers make landfall, they can contribute significantly to precipitation.
