Ridiculously Resilient Ridge

111:" of warm ocean water was caused by the persistence of the ridge and subsequent reduction in vertical ocean mixing due to storms, rather than the reverse. On the other hand, recent research suggests that unusual oceanic warmth in the western tropical Pacific Ocean may have played a role in triggering and maintaining the Triple R over successive seasons. High amplitude atmospheric ridge patterns similar to the Triple R have occurred more frequently in recent decades and there is evidence that the occurrence of persistent North Pacific geopotential height anomalies and anomalously dry California winters, will increase due to global warming, although uncertainty remains regarding the magnitude of these future changes. 2614: 20: 123: 2628: 1570: 95:
