Meteorology · Global Circulation — Subtropical Highs
The semi-permanent subtropical high-pressure cells (e.g., the Bermuda-Azores High) are associated with:
- AGenerally settled weather, light winds near their centers, and the trade winds on their equatorward side✓ Correct
- BConstant gales and storms
- CPermanent fog
- DHeavy monsoon rain at their center
Explanation
Subtropical highs near 30° latitude bring sinking air, fair weather, and light variable winds near their centers (the 'horse latitudes'), while their circulation drives the trade winds equatorward and the prevailing westerlies poleward. Their seasonal position steers ocean weather and routing.
