Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Southern Annular Mode variability | Statement: [Antarctic Circumpolar Current, affectedBy, Southern Annular Mode variability]

Target entity: Southern Annular Mode variability
Context triple: [Antarctic Circumpolar Current, affectedBy, Southern Annular Mode variability]

• A. Madden–Julian Oscillation
  The Madden–Julian Oscillation is a large-scale tropical atmospheric pattern characterized by eastward-moving pulses of enhanced and suppressed rainfall that strongly influence global weather and climate variability on intraseasonal timescales.
• B. 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.
• C. El Niño–Southern Oscillation
  El Niño–Southern Oscillation is a recurring climate pattern involving temperature and pressure changes in the tropical Pacific that strongly influences global weather and climate variability.
• D. Southern Oscillation
  The Southern Oscillation is a large-scale atmospheric pressure pattern across the tropical Pacific that drives the El Niño–Southern Oscillation climate phenomenon and influences global weather and rainfall.
• E. Southern Oscillation Index
  The Southern Oscillation Index is a standardized atmospheric pressure-based metric used to monitor and quantify the strength and phase of the El Niño–Southern Oscillation climate pattern.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Southern Annular Mode variability
Triple: [Antarctic Circumpolar Current, affectedBy, Southern Annular Mode variability]

Southern Annular Mode variability refers to fluctuations in the dominant pattern of atmospheric pressure and westerly wind strength encircling Antarctica, which strongly influence Southern Hemisphere climate and ocean circulation.
