Pacific–North American pattern

Target entity: Pacific–North American pattern
Context triple: [Arctic Oscillation, relatedTo, Pacific–North American pattern]

• A. North Pacific subtropical high
  The North Pacific subtropical high is a large, semi-permanent high-pressure system over the northeastern Pacific Ocean that strongly influences the region’s climate, winds, and ocean currents.
• B. Arctic Oscillation
  The Arctic Oscillation is a large-scale climate pattern characterized by opposing atmospheric pressure anomalies between the Arctic and mid-latitudes, strongly influencing weather and sea-ice conditions across the Northern Hemisphere.
• C. North Atlantic Oscillation
  The North Atlantic Oscillation is a large-scale atmospheric pressure pattern over the North Atlantic that strongly influences winter weather, storm tracks, and climate variability in Europe, North America, and the surrounding oceans.
• D. North Atlantic jet stream
  The North Atlantic jet stream is a fast-flowing, high-altitude air current that strongly influences weather patterns and storm tracks across the North Atlantic and adjacent continents.
• E. Pacific Decadal Oscillation
  The Pacific Decadal Oscillation is a long-term pattern of sea surface temperature variability in the North Pacific Ocean that shifts phases over decades and strongly influences regional climate and marine ecosystems.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Pacific–North American pattern
Target entity description: The Pacific–North American pattern is a major atmospheric teleconnection pattern in the Northern Hemisphere that describes recurring large-scale pressure and circulation anomalies over the North Pacific and North America, strongly influencing regional weather and climate variability.
