What primarily causes the seasonal shift between the Southwest Monsoon (Habagat) and the Northeast Monsoon (Amihan) in the Philippines?
Answer and explanation
Correct answer: D. differential heating between the Asian continental landmass and the surrounding Pacific and Indian Oceans
- Step 1: Monsoons are large-scale seasonal wind reversals driven by differential thermal capacity between land and ocean. Step 2. In northern summer, Asia heats up, drawing warm, moist southwest winds (Habagat). In winter, Siberian high pressure drives cool, dry northeast winds (Amihan). Answer: differential heating between the Asian continental landmass and the surrounding Pacific and Indian Oceans. Why not the others: Coriolis does not reverse semi-annually; tides are gravitational.
