Dramatic wind changes in the upper atmosphere have been found to affect the ocean, and effectively the climate.
It was already known that the upper atmosphere can influence the lower atmosphere, and weather in the lower atmosphere influences the ocean. However this new evidence demonstrates an entire link between all three.
Scientists used weather observations and 4,000 years of weather models to make an unlikely association between periodic changes in stratospheric wind patterns and deep-sea circulation patterns.
