Short summary

Connections between Long Island Sound (LIS) water temperature variability and modes of tropical sea surface temperature (SST) variability have yet to be explored. It is shown that intense LIS cold-water temperature events are related to central equatorial Pacific SSTs. The decay phase of such events may be related to canonical El Niño events. Furthermore, a ridge–trough atmospheric pattern related to LIS water temperature variability fluctuates coherently with central equatorial Pacific SSTs.
