Tide‐Storm Surge Interactions in Highly Altered Estuaries: How Channel Deepening Increases Surge VulnerabilityJournal of Geophysical Research: Oceans - Tập 125 Số 4 - 2020
Ramin Familkhalili, Stefan A. Talke, David A. Jay
AbstractWe develop idealized analytical and numerical models to study how storm surge amplitudes vary within frictional, weakly convergent, nonreflective estuaries. Friction is treated using Chebyshev polynomials. Storm surge is represented as the sum of two sinusoidal components, and a third constituent represents the semidiurnal tide (... hiện toàn bộ
River‐tide dynamics: Exploration of nonstationary and nonlinear tidal behavior in the Yangtze River estuaryJournal of Geophysical Research: Oceans - Tập 120 Số 5 - Trang 3499-3521 - 2015
Leicheng Guo, Mick van der Wegen, David A. Jay, Pascal Matte, Zheng Bing Wang, Dano Roelvink, Qing He
AbstractRiver‐tide dynamics remain poorly understood, in part because conventional harmonic analysis (HA) does not cope effectively with nonstationary signals. To explore nonstationary behavior of river tides and the modulation effects of river discharge, this work analyzes tidal signals in the Yangtze River estuary using both HA in a nonstationary mode and continu...... hiện toàn bộ
Long‐Term Trend of the Tropical Pacific Trade Winds Under Global Warming and Its CausesJournal of Geophysical Research: Oceans - Tập 124 Số 4 - Trang 2626-2640 - 2019
Yang Li, Quanliang Chen, Xiaoran Liu, Jianping Li, Nan Xing, Fei Xie, Juan Feng, Xin Zhou, Hongke Cai, Zhenglin Wang
AbstractThe recent intensification of trade winds over the tropical Pacific is the strongest ever observed in the past hundred years. This strengthening trend is of great interest in recent research, but the causes are still unclear. Using two relatively long‐term surface wind data sets, the present research shows that there is an overall strengthening trend of the...... hiện toàn bộ
Clusters, deformation, and dilation: Diagnostics for material accumulation regionsJournal of Geophysical Research: Oceans - Tập 120 Số 10 - Trang 6622-6636 - 2015
Helga S. Huntley, B. L. Lipphardt, Gregg Jacobs, A. D. Kirwan
AbstractClusters of material at the ocean surface have been frequently observed. Such accumulations of material play an important role in a variety of applications, from biology to pollution mitigation. Identifying where clusters will form can aid in locating, for example, hotspots of biological activity or regions of high pollutant concentration. Here cluster stre...... hiện toàn bộ
Numerical Modeling of the Interactions of Oil, Marine Snow, and Riverine Sediments in the OceanJournal of Geophysical Research: Oceans - Tập 123 Số 8 - Trang 5388-5405 - 2018
Anusha L. Dissanayake, Adrian Burd, Kendra L. Daly, Simone Francis, Uta Passow
AbstractNatural or spilled oil in the ocean can interact with marine snow and sediment from riverine sources and form Marine Oil Snow (MOS) aggregates including aggregates consisting of phytoplankton, detritus, and feces. Such aggregates have a fractal structure and can transport oil from the surface layers to greater depths in the ocean, eventually settling on the...... hiện toàn bộ
Impacts of Diverse El Niño Events on North Tropical Atlantic Warming in Their Decaying SpringsJournal of Geophysical Research: Oceans - Tập 126 Số 10 - 2021
Weihao Guo, Rongwang Zhang, Xin Wang
AbstractPrevious studies have demonstrated that North Tropical Atlantic (NTA) warming can be modulated by El Niño events through atmospheric teleconnections. Considering the diversity of El Niño events, this study focuses on different responses of the NTA sea surface temperature (SST) to eastern Pacific (EP), central Pacific type I and type II (CP‐I and CP‐II) El N...... hiện toàn bộ
Physical controls on hypoxia in Chesapeake Bay: A numerical modeling studyJournal of Geophysical Research: Oceans - Tập 118 Số 3 - Trang 1239-1256 - 2013
Malcolm E. Scully
ABSTRACTA three‐dimensional circulation model with a relatively simple dissolved oxygen model is used to examine the role that physical forcing has on controlling hypoxia and anoxia in Chesapeake Bay. The model assumes that the biological utilization of dissolved oxygen is constant in both time and space, isolating the role that physical forces play in modulating o...... hiện toàn bộ
