静止轨道卫星观测杭州湾悬浮泥沙浓度的动态变化及动力分析
Diurnal variation of suspended sediment concentration in Hangzhou Bay from geostationary satellite observation and its hydrodynamic analysis
摘要
Abstract
A semi-empirical radiative transfer (SERT) model is employed to retrieve suspended sediment concentration (SSC) in the Hangzhou Bay using Geostationary Ocean Color Imager (GOCI) data that have 8 scenes in each day. A three-dimensional (3-D) unstructured-grid, free-surface, primitive equation, Finite-Volume Coastal Ocean Model (FVCOM) is applied to simulate tidal current distribution in the Hangzhou Bay at the moment of GOCI overpass. Diurnal variation of the SSC distribution from the GOCI observation and hydrodynamic environment from FVCOM simulation are comprehensively analyzed. The results show that the SSC has a change with tide rise and fall during a tidal cycle. The flow changes should be the main impact factors on the SSC distribution in the Bay. The effects of wind-driven waves cause the SSC in winter larger than in summer.关键词
