Surface winds in the Northern Hemisphere flow: MCQ with Answer and Explanation

Surface winds in the Northern Hemisphere flow:
A. Across isobars towards high pressure
B. Across isobars towards low pressure
C. Perpendicular to isobars
D. Parallel to isobars
Answer: Option B
Solution (By JKSSB Mock Tests)
Surface winds in the Northern Hemisphere flow across isobars towards low pressure due to friction, which reduces the Coriolis force and causes the wind to spiral inward toward the low-pressure center.

Question #1
What is the name of the phenomenon where there is a reversal of the surface winds and ocean currents in the Indian Ocean?
A. La Niña
B. El Niño
C. Southern Oscillation
D. Indian Ocean Dipole

Correct Answer: Option D


Explanation:
The Indian Ocean Dipole involves changes in sea surface temperatures and wind patterns across the Indian Ocean, leading to reversals in surface winds and currents during positive and negative phases.

Question #2
Which of the following is a characteristic of a cold front?
A. Light rain
B. Gradual temperature change
C. Steep temperature gradient
D. Slow movement

Correct Answer: Option C


Explanation:

Question #3
Which of the following is a characteristic of the troposphere?
A. Decreasing temperature with altitude
B. Constant temperature with altitude
C. Increasing temperature with altitude
D. No weather phenomena

Correct Answer: Option A


Explanation:
The troposphere is characterized by decreasing temperature with altitude (normal lapse rate) due to adiabatic cooling, and it contains most of the weather phenomena.
