Oceanography: Stirring times in the Atlantic

Bob Dickson1

Set against certain other oceanographic phenomena in the northwest Atlantic, a class of brief and localized events that occur in the Irminger Sea may seem inconsequential. Not so, however.

On page 152 of this issue, Pickart et al.1 describe the winter incidence and climatology of so-called 'tip-jet events' off southern Greenland, their association with storm centres tracking northeastward into the Denmark Strait, and their effect in producing episodes of deep convective exchange in the Irminger Sea to the southeast of Greenland. That tip jets should have this effect is no surprise in itself.
