Meteorology · Global Circulation — Horse Latitudes
The 'horse latitudes' near 30°N and 30°S are regions of:
- AFrequent gales and low pressure
- BSubtropical high pressure with subsiding air, light winds, and generally fair, dry weather✓ Correct
- CConverging trade winds and heavy rain
- DPermanent fog
Explanation
Around 30° latitude, descending air of the Hadley circulation forms the subtropical high-pressure belts (horse latitudes), giving light winds, clear skies, and little rain — the source regions of the trade winds equatorward and the westerlies poleward.
