Analyzing the Somali Current System

The question asks to identify the INCORRECT statement regarding the Somali current system. Let's analyze each option:

1. Great Whirl Existence

The Somali current system is characterized by a large anticyclonic circulation cell known as the Great Whirl, especially prominent during the summer monsoon. Therefore, statement 1 is correct.

2. Seasonal Reversal Characteristic

The Somali current is a unique, wind-driven ocean current. It flows northward along the Somali coast during the northeast monsoon (winter) and southward along the coast during the southwest monsoon (summer). This demonstrates a distinct seasonal reversal. The statement that it does not experience seasonal reversal is therefore incorrect.

3. Coastal Upwelling Occurrence

During the summer monsoon, strong winds parallel to the Somali coast drive intense coastal upwelling. This process brings cold, nutrient-rich deep water to the surface, supporting high biological productivity. Thus, statement 3 is correct.

4. Socotra Eddy Association

The Socotra eddy is an anticyclonic feature often observed in the vicinity of the Somali current system, particularly off the coast of Socotra island. It is intrinsically linked to the dynamics of the Somali current. Statement 4 is correct.

Conclusion

Based on the analysis, the statement that the Somali current does not experience seasonal reversal is factually wrong. The Somali current system is well-known for its significant seasonal changes driven by the monsoonal winds.
