Here the focus is on estuarine locations not only affected by tide and surge propagation, but also potentially influenced by freshwater discharge.
Changes in depth due to the ocean tide, alter the tsunami propagation, amplification, and dissipation, thus it is crucial in modelling studies that the tide and tsunami are appropriately coupled to reduce the limitations of the model24,25,26.
The underlying causes of weather phenomena (sporadic E layers, intermediate layers, and equatorial electrojet) can be traced to the propagation of tides and gravity waves from the lower atmosphere.
The tidal effects at both the E and F layers indicate the upward propagation of tides from the lower atmosphere into the thermosphere.
In many cases, remarkable consistency is achieved, which serves as a validation of the technique employed to derive the tidal spectrum for the upper thermosphere and the theory that predicts the vertical propagation of tides in a diffusive thermosphere.
This temperate mesotidal estuary is limited upstream by a hydroelectric power dam that controls freshwater inflow and prevents the propagation of the tide upstream, which, in turn, influences water circulation and biogeochemical dynamics of the system.
The phase decreases with height, which indicates the upward propagation of the tide Dw1 in this region.
They provide the means to examine the tidal structure cleanly (observations are generally affected by sampling issues) and help in the interpretation of the observed features through investigation of physical mechanisms such as tidal forcing, tidal propagation and dissipation, and tide-mean flow and tide-wave interactions.
Tides can modify the upward propagation of gravity waves and their momentum deposition in the MLT region via critical layer filtering mechanisms (Fritts and Vincent 1987) and via modulation of the buoyancy frequency (Preusse et al. 2001).
