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: Brunt–Väisälä frequency | Statement: [Ledoux criterion, relatesTo, Brunt–Väisälä frequency]

Target entity: Brunt–Väisälä frequency
Context triple: [Ledoux criterion, relatesTo, Brunt–Väisälä frequency]

• A. Rossby number
  The Rossby number is a dimensionless quantity in fluid dynamics and meteorology that compares inertial to Coriolis forces, indicating the importance of Earth's rotation in large-scale atmospheric and oceanic flows.
• B. Kelvin–Helmholtz instability
  Kelvin–Helmholtz instability is a fluid dynamical phenomenon in which velocity shear between layers of fluid (or plasma) with different densities leads to characteristic wave-like billows and turbulent mixing at their interface.
• C. Froude number
  The Froude number is a dimensionless quantity in fluid dynamics that compares inertial forces to gravitational forces, commonly used to characterize flow regimes in open channels and around ships.
• D. Saffman
  Saffman is a surname most notably associated with Philip G. Saffman, a prominent British-American applied mathematician and fluid dynamicist.
• E. Chandrasekhar number
  The Chandrasekhar number is a dimensionless quantity in magnetohydrodynamics that measures the relative importance of magnetic forces compared to viscous forces in a conducting fluid.
• 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

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: Brunt–Väisälä frequency
Triple: [Ledoux criterion, relatesTo, Brunt–Väisälä frequency]

The Brunt–Väisälä frequency is a measure of the stability of a stratified fluid to vertical displacements, representing the natural oscillation frequency of buoyancy-driven gravity waves in atmospheres, oceans, and stellar interiors.
