Triple

Target class: subtropical high-pressure system
Context triple: [Azores High, instanceOf, subtropical high-pressure system]

• A. anticyclonic storm chosen
  An anticyclonic storm is a large-scale weather system characterized by high atmospheric pressure at its center and winds that rotate opposite to the typical cyclonic direction for that hemisphere, often bringing clearer and more stable conditions.
• B. subpolar region
  A subpolar region is a geographic area located just outside the polar circles, characterized by cold climates with long, severe winters, short cool summers, and transitional ecosystems between polar and temperate zones.
• C. regional wind
  A regional wind is a persistent or recurring air movement pattern that is characteristic of and largely confined to a specific geographic area, influenced by local topography, land–sea contrasts, and regional climate conditions.
• D. katabatic wind
  A katabatic wind is a gravity-driven downslope wind that occurs when dense, cold air flows from higher elevations to lower areas, often producing strong, gusty conditions in valleys and coastal regions.
• E. North Indian Ocean cyclone
  A North Indian Ocean cyclone is a powerful, rotating storm system that forms over the Bay of Bengal or Arabian Sea, characterized by low atmospheric pressure, strong winds, and heavy rainfall, often leading to coastal flooding and severe damage in surrounding regions.
• F. None of above.
