How this entity was disambiguated
This entity first appeared as the object of triple T3091760 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

gpt-5-mini-2025-08-07
Target entity: Rossby waves Context triple: [Madden–Julian Oscillation, relatedTo, Rossby waves]
-
A.
Ekman transport
Ekman transport is an oceanographic process in which wind-driven surface waters move at an angle to the wind direction due to the Coriolis effect, causing net water transport perpendicular to the wind.
-
B.
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.
-
C.
Ekman layer
The Ekman layer is the thin region of fluid near a boundary (such as the ocean surface or seafloor) where the balance between friction and the Coriolis effect causes the flow to spiral with depth.
-
D.
Bjerknes circulation theorem (applications in meteorology)
The Bjerknes circulation theorem is a fundamental principle in meteorology that relates changes in atmospheric circulation to forces such as pressure gradients and heating, forming a basis for understanding large-scale weather systems and cyclogenesis.
-
E.
Coriolis effect
The Coriolis effect is the apparent deflection of moving objects caused by Earth's rotation, strongly influencing global wind patterns and ocean currents.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Rossby waves Description of subject: Rossby waves are large-scale atmospheric and oceanic waves driven by Earth's rotation and the variation of the Coriolis effect with latitude, playing a key role in shaping global weather and climate patterns.
