New perspective on sea level dynamics along east coast of America

Editor’s Highlight—

 

This paper addresses the spatial and temporal variability of coastal sea level rise along the eastern American coast, a region that has been known for exceptional sea level rise rates and accordingly received some attention. The authors investigate the causes of so-called sea level hotspots, and conclude that they are forced by a combination of teleconnection (El Niño Southern Oscillation) and regional (North Atlantic Oscillation) processes that govern the timing and position of these hot spots. The results are interesting with respect to future short-term sea level changes. 


Blog—Rapidly rising seas: Scientists discover cause of Atlantic coastline’s sea level rise hot spots

Sea level rise hot spots — bursts of accelerated sea rise that last three to five years — happen along the U.S. East Coast thanks to a one-two punch from naturally occurring climate variations, a new University of Florida study shows.

After UF scientists identified a hot spot reaching from Cape Hatteras to Miami, they probed the causes by analyzing tidal and climate data for the U.S. eastern seaboard. The new study, published online today in Geophysical Research Letters, a journal of the American Geophysical Union, shows that seas rose in the southeastern U.S. between 2011 and 2015 by more than six times the global average sea level rise that is already happening due to human-induced global warming.

The study’s findings suggest that future sea level rise resulting from global warming will also have these hot spot periods superimposed on top of steadily rising seas…more

A Census of Atmospheric Variability from Seconds to Decades 

The atmosphere varies naturally on all length scales from millimeters to thousands of kilometers, and on all time scales from seconds to decades and longer.  This special collection of Geophysical Research Letters synthesizes and summarizes that variability through a phenomenological census.  The collection brings together some of the most influential and definitive papers to have been published in this journal in recent years.  The topics covered include turbulence on time scales of seconds and minutes, gravity waves on time scales of hours, weather systems on time scales of days, atmospheric blocking on time scales of weeks, the Madden–Julian Oscillation on time scales of months, the Quasi-Biennial Oscillation and El Niño–Southern Oscillation on time scales of years, and the North Atlantic, Arctic, Antarctic, Pacific Decadal, and Atlantic Multi-decadal Oscillations on time scales of decades.  The collection is accompanied by a Commentary article, which provides an authoritative, concise, and accessible point of reference for the most important modes of atmospheric variability.
