New research sinks an old theory for the doldrums, a low-wind equatorial region that stranded sailors for centuries

During the Age of Sail, sailors riding the trade winds past the equator dreaded becoming stranded in the doldrums, a meteorologically distinct region in the deep tropics. For at least a century, scientists have thought that the doldrums' lack of wind was caused by converging and rising air masses. Now, new research suggests that the opposite may be true.
