Abstract Numerous tidal phenomena, including river tides, internal and tides in ice‐covered bay, are nonstationary, which pose a great challenge for traditional analysis methods. Based on the independent point scheme cubic spline interpolation, new approach, namely enhanced harmonic analysis, is developed to deal with nonstationary tides. A MATLAB toolbox, S_TIDE, from widely used T_TIDE, realize approach. The efficiency of S_TIDE validated by analyzing set hourly water level observations...
Due to the strong nonlinear interaction with river discharge, tides in estuaries are characterised as nonstationary and their mechanisms yet be fully understood. It remains highly challenging accurately predict estuarine water levels. Machine learning methods, which offer a unique ability simulate unknown relationships between variables, have been increasingly used large number of research areas. This study applies LightGBM model predicting levels along lower reach Columbia River. The inputs...
Abstract. The seasonal variation of tides plays a significant role in water level changes coastal regions. In this study, variations four principal tidal constituents, M2, S2, K1, and O1, the Bohai Sea, China, were studied by applying an enhanced harmonic analysis method to two time series: 1-year sea observations at mooring station (named E2) located western Sea 17-year Dalian. At E2, M2 amplitude phase lag have annual frequencies, with large values summer small winter, while frequencies S2...
As a ubiquitous movement in the ocean, tides are vital for marine life and numerous activities such as fishing ocean engineering. Tidal dynamics complicated East Asian marginal seas (EAMS) due to changing complex topography coastlines related human (e.g., land reclamation channel deepening) natural variability seasonal variations of stratification river flow). an important tool, numerical models widely used because they can provide basin-scale patterns tidal compared point-based tide gauges....
Abstract As an effective tool to distinguish different tidal components, classical current harmonic analysis has been widely used obtain parameters of internal currents. However, cannot exactly reveal the motion tides, as irregular temporal variations for tides are significant in many regions world’s oceans. An enhanced (EHA) algorithm based on independent point scheme and cubic spline interpolation is presented this paper with constituents tides. Moreover, applied analyze 14 months data...
Abstract A lot of tidal phenomena, including river tides, tides in ice-covered bays, and internal fjords, are nonstationary. These processes present a severe challenge for the conventional analysis method. The empirical mode decomposition (EMD) method is useful nonstationary nonlinear time series has been used different geophysical data. However, application EMD to rare. This paper meant demonstrate new tool that can help study this case tides. applied set hourly water level records on lower...
Abstract The detection of water transparency ( Z sd ) changes over multiple timescales is an important task that has wide implications from quality to climate change research. However, date, the understanding variations and their driving factors in Eastern China Seas fairly limited. Using Data Interpolating Empirical Orthogonal Functions (DINEOF) method a semi‐analytic algorithm, monthly cloud‐free products period 1997–2019 are retrieved European Space Agency Ocean Color Climate Change...
Abstract Open boundary conditions (OBCs) of the M 2 tidal constituent in Bohai and Yellow Seas (BYS) were inverted successfully through assimilation TOPEX/Poseidon (T/P) altimeter data. An improved independent points (IPs) scheme was employed inversion. Under assumption that OBC spatially varying, values at a set IPs along open using adjoint method those other calculated by spline interpolation. The with closer to reality terms smoothness than Cressman calibrated twin experiments. Practical...
Understanding nodal tidal characteristics is essential for accurate long-term prediction. Observational evolution of tides mainly based on tide gauge records in coastal areas which are limited time and space, thus impeding coherent determinations basin-wide patterns variability. In this paper, we indicate the potential satellite altimeter data to investigate 18.61-year modulations main constituents Gulf Tonkin. Three gauges multi-source observations (TOPEX/Poseidon, Jason1, Jason2, Jason3)...
Exploring multi-timescale tidal variability is fundamental and necessary for numerous practical purposes, such as flood protection, marine cultivation, ocean transport. It well known that tides show significant seasonal, inter-annual, 18.61-year nodal variability. Less less discussed the subseasonal (i.e., ter-annual, quarter-annual, penta-annual cycles) in coastal ocean. In this study, we explore modulations Gulf of Tonkin via combination four tide gauges 27-year multi-satellite altimeter...
