摘要: Abstract The wave model WAM was used to study the effect of grid resolution and description an irregular shoreline on modelling fetch-limited growth. Three different methods compile a for in case are discussed. Several combinations description, resolution, wind field were irregularities confirmed usual assumption that these effects will rapidly vanish as distance from shore increases. However, close differences between modelled values significant height relatively large. spectral parameters compared against measurements made Bothnian Sea 1976. None able accurately predict measured Close energy peak period grew too fast, further offshore underestimated. most accurate results obtained when high-resolution 0.25 nmi together with re-analysed atmospheric HIRLAM. growth rate at short fetch
