(instance Nino3 NinoRegion)	Weather.kif 873-873	Nino 3 is an instance of Nino region
(documentation Nino3 EnglishLanguage "Nino3 lies between 5N-5S and 150W-90W. This region was once the primary focus for monitoring and predicting El Niño, but researchers later learned that the key region for coupled ocean-atmosphere interactions for ENSO lies further west (Trenberth, 1997). Hence, the Niño 3.4 and ONI became favored for defining ElNinoPhaseo and LaNinaPhase events.[US National Science Foundation, National Center For Atomspheric Research]")	Weather.kif 874-878	Nino 3 is an instance of Nino region
