Question:
Statement I: Periodically, a phenomenon called as southern oscillation that is a global scale see-saw in surface pressure with center of action near Indonesia - North Australia in one side and South-east Pacific region in the other side occurs and when it occurs the above mentioned normal situation greatly changes.
Statement II: Pressure rises in the Indonesian region and as a consequence the steady Trade wind diminish and may even change direction.
In light of the above statements, choose the correct answer from the options given below:

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Southern Oscillation is a climatic phenomenon.
It involves pressure changes in the Pacific region.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand Southern Oscillation.
Step 3: Detailed Explanation:
Statement I: Southern Oscillation is a see-saw in surface pressure.
It involves Indonesia-North Australia and Southeast Pacific.
This is correct.
Statement II: Pressure rises in Indonesia, Trade winds diminish or change direction.
This is also correct.
Thus, both statements are true.
Step 4: Final Answer:
Both Statement I and Statement II are true.
Hence, the correct option is (A).
