WASHINGTON — Global warming could reduce how many hurricanes hit the United States, according to a new federal study that clashes with other research. The new study is the latest in a contentious scientific debate over how man-made global warming may affect the intensity and number of hurricanes.

In it, researchers link warming waters, especially in the Indian and Pacific oceans, to increased vertical wind shear in the Atlantic Ocean near the United States. Wind shear?– a change in wind speed or direction?– makes it hard for hurricanes to form, strengthen and stay alive.

So that means “global warming may decrease the likelihood of hurricanes making landfall in the United States,” according to researchers at the National Oceanic and Atmospheric Administration’s Miami Lab and the University of Miami.

Wang said he based his study on observations instead of computer models and records of landfall hurricanes through more than 100 years.
