This has resulted in a modest suppression of 200 mb upper tropospheric easterly wind anomalies in the tropical Atlantic, thereby increasing vertical wind shear in the western Atlantic. (realclimate.org)
El Niño, the large - scale weather pattern that creates strong wind shear in the upper levels of the atmosphere, disrupts storm formation. (sun-sentinel.com)
The National Weather Service predicts increased vertical wind shear over the Caribbean Sea and this limits hurricanes, so they're predicting an average season. (scientificamerican.com)
