Coastal Surges front Extratropical Storms on the West Coast of the Korean Peninsula

Abstract

Coastal surges along the west coast of the Korean Peninsula from extratropical storms were investigated using tide gage observations for one year and numerical model hindeasting. Positive surges were associated with smaller scale meteorological forcing than negative surges. Spatial and temporal variations among different locations characterized typical surge propagation from south to north along the west coast and from west to east across the Yellow Sea. Forecasting is feasible with meteorological forcing input with around 1° - 1.5° spatial and 6 hourly temporal resolutions.
