Temporal energy partitions of Florida extreme sea level events as a function of Atlantic multidecadal oscillation South Florida Water Management District, Hydrologic & Environmental Systems Modeling, West Palm Beach, FL, USA
Received: 29 Jan 2010 – Published in Ocean Sci. Discuss.: 11 Mar 2010Abstract. An energy-conservative metric based on the discrete wavelet transform is
applied to assess the relative energy distribution of extreme sea level
events across different temporal scales. The metric is applied to coastal
events at Key West and Pensacola Florida as a function of two Atlantic
Multidecadal Oscillation (AMO) regimes. Under AMO warm conditions there is a
small but significant redistribution of event energy from nearly static into
more dynamic (shorter duration) timescales at Key West, while at Pensacola
the AMO-dependent changes in temporal event behaviour are less pronounced.
Extreme events with increased temporal dynamics might be consistent with an
increase in total energy of event forcings which may be a reflection of more
energetic storm events during AMO warm phases. As dynamical models mature to
the point of providing regional climate index predictability, coastal
planners may be able to consider such temporal change metrics in planning
