Investigation of the impact of desalination on the salinity of the Persian Gulf
… from precipitation and some from river flow. A residual circulation exists between the Gulf and the Indian Ocean such that saline water flows into the Gulf from the Indian Ocean in order to balance the freshwater deficit due to high evaporation rate; and since evaporation only removes …

Circulation through the mouth of Langebaan Lagoon and implications
… Langebaan Lagoon inlets generated a Lagrangian residual circulation, with the east inlet constituting the entrance for Saldanha Bay water, while the west inlet would be the exit route for Langebaan Lagoon water. Southerly winds, contributed to the overall residual circulation by driving water …

Transverse Variability of the Flow and Density in Inlets of Southern Chile
… combination determined differences in the residual circulation on both sides of the contraction. The subtidal transverse momentum balance in Aysen alternates from quasigeostrophic during calm winds to a frictional layer and quasigeostrophic interior during periods of wind forcing. In …

Stratosphere - troposphere interaction during stratospheric sudden warming events
… (EP) flux is closely balanced by the residual circulation dominated by the Coriolis term on a daily basis, while the change in zonal wind is a small residual between these dominant terms. In the stratosphere, the EP flux term and the Coriolis term balance well in time but not exactly …

From Representative Period Selection to Process‐Based Sediment Dynamics
… comparatively understudied, and its typical residual and storm-driven sediment pathways are poorly understood. This thesis develops an integrated, process-based modelling framework to address these gaps. A high-resolution Delft3D-4 model of the NFWS was developed and validated to resolve …

Transport and retention of benthic marine invertebrates in the Southern Tauranga Basin
… modelling vary throughout the harbour, due to residual circulation patterns caused by complex channel morphology. Field observations indicate increased abundance and differing community composition of invertebrate larvae in the upper harbour compared to the lower. Tidal circulation is …

Freshwater Transport on the Continental Shelf of the Southeastern United States
<p>The circulation of water over the shelf of the southeastern United States was examined during the Fall Removal Experiment from late October to early November 1987. A steady state, two-dimensional analytical model of wind and density driven flow was used to study the relative importance of …

Downward influence of stratospheric final warming events in an idealized model
… of the final warmings on the tropospheric circulation. Results from our zonally symmetric model suggest that stratospheric wave driving can induce a residual circulation and affect the tropospheric circulation. The tropospheric signals due to this mechanism are, however, very weak and are …

Modeling the Dispersion of Eastern Oyster Larvae (<i>Crassostrea virginica</i>) and its Effects on the Movement of Disease Resistant Genes in the Delaware Bay Estuary
… spring-neap tides are the main forcing of the residual circulation. salinity and stratification in the Delaware estuary, playing an important role in the larval success and dispersion. Years with low success are related to large events of river discharge within the spawning season. Large river …

Trace Metal-Particle Water Interactions in the Western North Sea
… (SPM) suggesting long range transport with the residual circulation. Modelling of Pb isotopic ratios in the Humber Plume suggested that on average 32-39% of the extracted Pbp originated from anthropogenic sources The data from this study has given unique information concerning the concurrent …

Tropical transport and the seasonal variability of the subtropical "edges" in the stratosphere
… hemisphere result purely from the action of the residual circulation, which tends to increase potential vorticity and tracer values in the tropics and decrease them at high latitudes (for tracers with tropospheric sources and photochemical sinks) over the course of the summer. We show that the …

Gravity Wave and Turbulence Transport in the Mesopause Region
… structure and wave dissipation for the general circulation models (GCMs). The derived turbulence parameters and cooling/heating rates can provide significant references for parameterizing the wave-driven residual circulation by generating more realistic global thermal structures.</p>

Variationen der stratosphärischen Residualzirkulation und ihr Einfluss auf die Ozonverteilung
Die Residualzirkulation entspricht der mittleren Massenzirkulation und beschreibt die im zonalen Mittel stattfindenden meridionalen Transportprozesse. Die Variationen der Residualzirkulation bestimmen gemeinsam mit dem anthropogen verursachten Ozonabbau die jährlichen Schwankungen der …
