“El Niño's effect on the jet stream can impact tornado development in parts of the country, in what might be its most important impact on U.S. weather… A 2015 study led by John Allen from Columbia University found spring tornado activity can be suppressed in parts of the Plains during El Niño.”
“El Niño conditions can also influence the Atlantic hurricane season if they remain in effect into the summer and fall.
“In general, wind shear – the change in wind direction and/or speed with height – is stronger in the Atlantic Basin during El Niño hurricane seasons. Wind shear tends to reduce the number of named storms and hurricanes.
