Question 10

The jet stream that forms in summer near the tropopause above Southeast Asia, India, and Africa is known as the ____ jet stream.​
A) ​polar-front
B) ​tropical easterly
C) ​noctural
D) ​stratospheric polar night
E) ​low-level

Accepted Answer

The jet stream that forms in summer near the tropopause above Southeast Asia, India, and Africa is known as the tropical easterly jet stream. The other options either refer to different types of jet streams or are not related to the described situation.

Question 11

The ____ jet is known to show seasonal variations. In winter, the winds are stronger and the jet moves farther south as the leading edge of the cold air can extend into subtropical regions, as far south as Florida and Mexico. In summer, the jet is weaker and is usually found over more northerly latitudes.​
A) ​subtropical
B) ​tropical easterly
C) ​low-level
D) ​polar-front
E) ​nocturnal

Accepted Answer

The description given fits the polar-front jet, also known as the mid-latitude jet, which is driven by the temperature gradient between polar and subtropical regions.

Question 16

At the equator, Earth rotates toward the east at a speed close to 1000 knots. On a windless day, the air above moves ____ at ____ speed.​
A) ​northward; faster
B) ​eastward; the same
C) ​southward; slower
D) ​westward; faster
E) ​eastward; slower

Accepted Answer

The air above the Earth at the equator moves eastward at the same speed as the Earth's rotation because of the atmosphere's tendency to move in sync with the surface due to the friction and the Earth's rotation, which creates a relatively stable system where the air moves with the Earth.
