Explain why the semipermanent lows in the Southern Hemisphere are weaker than those in the Northern Hemisphere.?
What will be the ideal response?
ANSWER: In the North Atlantic, there is the Greenland-Icelandic low, or simply Icelandic low, which covers Iceland and southern Greenland, while the Aleutian low sits over the Gulf of Alaska and Bering Sea near the Aleutian Islands in the North Pacific. These zones of cyclonic activity represent regions where numerous storms, having traveled eastward, tend to converge, especially in winter. In the Southern Hemisphere, where there is very little land to disrupt the flow, the subpolar low forms a continuous trough that completely encircles the globe. Hence, the reason for semipermanent lows in the Southern Hemisphere being weaker than in the Northern Hemisphere is that the Southern Hemisphere is mostly covered in water.?
