Nearshore waves in southern California: hindcast, and modeled historical and 21st-century projected time series

Christie A. Hegermiller, Li H. Erikson & Patrick L. Barnard
As part of the Coastal Storm Modeling System (CoSMoS), time series of hindcast, historical, and 21st-century nearshore wave parameters (wave height, period, and direction) were simulated for the southern California coast from Point Conception to the Mexican border. The hindcast (1980-2010) time series represents reanalysis-forced offshore waves propagated to the nearshore, whereas the historical (1976-2005) and 21st-century (2012-2100) time series represent global climate model-forced offshore waves propagated to the nearshore. Changes in deep-water wave conditions...

Wave and Wind projections for United States Coasts; Mainland, Pacific Islands, and United States-Affiliated Pacific Islands

L.H. Erikson
Coastal managers and ocean engineers rely heavily on projected average and extreme wave conditions for planning and design purposes, but when working on a local or regional scale, are faced with much uncertainty as changes in the global climate impart spatially-varying trends. Future storm conditions are likely to evolve in a fashion that is unlike past conditions and is ultimately dependent on the complicated interaction between the Earth s atmosphere and ocean systems. Despite a...
