Research shows a strong link between the global warming hiatus and recent decadal-scale drought over North America, with the connection arising from the impact of unusually strong easterly winds on the tropical Pacific Ocean. These easterly winds cause enhanced upwelling of cold sub-surface water in the eastern Pacific. This relatively cold water creates a broad area of cooler water at the oceans surface. This, in turn, causes a global scale atmospheric response, including atmospheric ridging (high pressure and drying) extending from the central North Pacific through the western and southern U.S. This ridging systematically reduces the likelihood of precipitation over western North America. Most importantly...This and other research indicates that the prolonged western drought cycle will end at least temporarily as it has done in past decades due to this cycle as long as those winds decrease. That question is still being researched.
