A lot of people look forward to retirement only to find that it’s a more financially stressful period of life than expected. And a big part of the reason could boil down to being ill-prepared.
A bore in Morecambe Bay, in the United Kingdom Video of the Arnside Bore, in the United Kingdom The tidal bore in Upper Cook Inlet, in Alaska. A tidal bore, [1] often simply given as bore in context, is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay, reversing the direction of the river or bay's current.
The world's first marine energy test facility was established in 2003 to start the development of the wave and tidal energy industry in the UK. Based in Orkney, Scotland, the European Marine Energy Centre (EMEC) has supported the deployment of more wave and tidal energy devices than at any other single site in the world. EMEC provides a variety ...
The tidal wave, a Kelvin wave, enters the domain in the lower left corner and travels to the right with the coast on its right. The sea surface height (SSH, left panels of animation 1), the tidal elevation, is maximum at the coast and decreases towards the centre of the domain.
Much of the tidal wave's energy is sprawling and very deep below the sea surface. As a result, tidal waves may not be barely noticeable at sea but can extend miles inland upon reaching the coast.
Tsunamis, the large waves that occur after earthquakes, are sometimes called tidal waves, but this name is given by their resemblance to the tide, rather than any causal link to the tide. Other phenomena unrelated to tides but using the word tide are rip tide , storm tide , hurricane tide , and black or red tides .
A storm surge, or tidal surge, which can cause waves that breach flood defences A tsunami , a series of water waves in a body of water caused by the displacement of a large volume of water, although this usage of "tidal wave" is a misnomer and is disfavored by the scientific community.
Figure 2. Eigenvalue ε of wave modes of zonal wave number s = 1 vs. normalized frequency ν = ω/Ω where Ω = 7.27 × 10 −5 s −1 is the angular frequency of one solar day. Waves with positive (negative) frequencies propagate to the east (west). The horizontal dashed line is at ε c ≃ 11 and indicates the transition from internal to ...
