No abstracts are to be cited without prior reference to the author.

The observed changes in the direction of the abundance indices correspond with changes in trends in the size of the Atlantic Warm Pool (AWP), the change in sign of the Atlantic Multidecadal Oscillation (AMO), and the North Atlantic Oscillation (NAO).
