# Douglas sea state

This actually has two scales; one for the wind generated waves, and the other for the background swell. Ideally one should use both scales to fully describe the conditions.The depth of the water also has an impact on swell characteristics. As waves move into shallow water, the waves begin to interact with the sea bed.  The result of this friction is an increase in wave height: this process is known as shoaling. The increase in wave steepness continues until the wave breaks. MetService uses a variety of techniques to forecast swell waves. Nomograms are an effective graphical technique to estimate characteristic wave heights and periods. Bretschneider devised a nomogram in the mid-1900s, based on very large amounts of wave data, called the Bretschneider nomogram (see figure seven). if yes state number of air changes per hour basis empty holds. 3.2 deck and hatches. 4.2 state vessel`s consumption at economic speed(upto beaufort scale force 4/ douglas sea state 3) as..

"I have read the DDDB from its inception and believe that it is, in context, a valuable contribution to safety at sea."A wave in the ocean is a disturbance that travels through water, accompanied by a transfer of energy. When the wind blows across the ocean, it creates wind waves. Over time these build up and become larger, self-sustaining ocean waves that travel beyond the area of wind that created them. Wind waves are not self-sustaining and will die out when the wind stops.

I would like to suggest that you might consider expanding the DDDB so that, in the future, one could access a new design or an existing vessel and pass an intelligent judgment on its behavior in gale force winds. I hold the opinion that the prismatic coefficient, location and shape of the maximum section, shape of the buttocks, shape of the keel, rig, and shape of the hull above the waterline all play an important role in the behavior of the vessel in gales and the probability of needing to deploy a drag device."

### State of the sea (wind sea)

United States The term Sea State describes the general condition of the surface of the open sea. This is comprised of two core measurements, the wave height which is dependent on the local surface wind strength and thus termed the 'wind sea' and the swell which is a slow and regular movement of the sea in rolling.. A swell, in the context of an ocean, sea or lake, is a series of mechanical waves that propagate along the interface between water and air and thus are often referred to as surface gravity waves. These series of surface gravity waves are not wind waves, which are generated by the immediate local wind, but instead are generated by distant weather systems, where wind blows for a duration of time over a fetch of water. More generally, a swell consists of wind-generated waves that are not—or are hardly—affected by the local wind at that time. Swell waves often have a long wavelength, but this varies due to the size, strength and duration of the weather system responsible for the swell and the size of the water body. Swell wavelength also varies from event to event. Occasionally, swells which are longer than 700 m occur as a result of the most severe storms. Swells have a narrower range of frequencies and directions than locally generated wind waves, because swell waves have dispersed from their generation area, have dissipated and therefore lost an amount of randomness, taking on a more defined shape and direction. Swell direction is the direction from which the swell is coming. It is measured in degrees, and often referred to in general directions, such as a NNW or SW swell. Thank you for the explanation but I am not clear on when there is no express reference to swell, how the combined sea height will be determined and what it exactly means. Could you make further explanations about it?

• ed the wind speed, fetch length and wind duration, the wave height and period can be estimated. Example 1: Consider a wind of 30 knots blowing over a fetch of length 80 nautical miles for a duration of 12 hours. Using the Bretschneider nomogram, follow the 30 knot line across until you arrive at one of the constraints. In this case, you reach the fetch length constraint before you get to the time constraint. At the intersection of 30kt and 80nm, the significant wave is read off as approximately 10 feet/3 metres (yellow line) in height with a period of 7 seconds (orange line).

In mathematics, a root system is a configuration of vectors in a Euclidean space satisfying certain geometrical properties. The concept is fundamental in the theory of Lie groups and Lie algebras, especially the classification and representation theory of semisimple Lie algebras. Since Lie groups and Lie algebras have become important in many parts of mathematics during the twentieth century, the apparently special nature of root systems belies the number of areas in which they are applied. Further, the classification scheme for root systems, by Dynkin diagrams, occurs in parts of mathematics with no overt connection to Lie theory. Finally, root systems are important for their own sake, as in spectral graph theory.

This is to cover such hazards as erosion, waterfront safety and infrastructure inundation. The warning criteria have been set by the individual councils and are different for each area; most have a threshold of around 3.5m in height, with some more sensitive thresholds set according to other meteorological conditions such as atmospheric pressure and wind strength. Although swell is strictly the determining factor, in practice it is combined waves (including all landward swells and the contribution of wind waves) that are used as the forecast parameter.

Sea-level scientists painted a portrait of a changing planet at a major science conference in San Francisco In transcendental number theory, a mathematical discipline, Baker's theorem gives a lower bound for the absolute value of linear combinations of logarithms of algebraic numbers. The result, proved by Alan Baker, subsumed many earlier results in transcendental number theory and solved a problem posed by Alexander Gelfond nearly fifteen years earlier. Baker used this to prove the transcendence of many numbers, to derive effective bounds for the solutions of some Diophantine equations, and to solve the class number problem of finding all imaginary quadratic fields with class number 1.

1. Example 2: Consider a wind of 60 knots blowing over a fetch of length 600 nautical miles for a duration of 24 hours. Using the nomogram, follow the 60 knot line across until you arrive at one of the constraints. In this case, you reach the time constraint before you get to the fetch length constraint. At the intersection of 60kt and 24 hours, the significant wave is read off as approximately 45 feet/13.7 metres (yellow line) in height with a period of 15 seconds (orange line).
2. In your previous comment you say that ‘recent litigation on this has led to a consensus that Sea State of 3, when quoted alone without reference to swell, would allow for a combined sea height (waves plus swell)’, that’s why i asked what combined sea height means. For examples if height of waves 1m and height of swell 2m , will we say that height in total is 3m, so that conditions in overall is douglas sea scale 5? I do not think that this is what they mean in that dispute!
3. Having said that, in many cases the swell part is not quoted. This seems to cause a lot of problems for charter companies who warranty certain performance characteristics in certain conditions, such as the ability to do X knots in good sea conditions. By this they, apparently, usually mean a Sea State of 3. But does that ignore the swell? Recent litigation on this has led to a consensus that a Sea State of 3, when quoted alone without reference to swell, would allow for a combined sea height (waves plus swell) of 2 meters. So, for your example, if you were really going to quote only one number, then probably you should quote 4. However, it is clearly much better to quote separately the sea and swell states. Unfortunately, even Met offices rarely do this. The Italian forecasts, for example, quote only the expected Sea State.
5. Scales for the range of both wave height and swell wavelength were developed and adopted by the Royal Navy in the 1920s and collectively became known as the Douglas Sea Scale.

In differential geometry, a tensor density or relative tensor is a generalization of the tensor field concept. A tensor density transforms as a tensor field when passing from one coordinate system to another, except that it is additionally multiplied or weighted by a power W of the Jacobian determinant of the coordinate transition function or its absolute value. A distinction is made among (authentic) tensor densities, pseudotensor densities, even tensor densities and odd tensor densities. Sometimes tensor densities with a negative weight W are called tensor capacity. A tensor density can also be regarded as a section of the tensor product of a tensor bundle with a density bundle.

The tails of the distribution decrease more slowly than the normal distribution. It is therefore suitable to model phenomena where numerically large values are more probable than is the case for the normal distribution. Examples are returns from financial assets and turbulent wind speeds. The distribution was introduced in the financial literature by Madan and Seneta.

Douglas, who later became vice admiral Sir Percy Douglas and hydrographer of the Royal Navy. Its purpose is to estimate the roughness of the sea for navigation. The scale has two codes: one code is for estimating the sea state, the other code is for describing the swell of the sea. [1] The routine aviation use of Sea State Codes is largely limited to over sea helicopter operations. On the rare occasions when fixed wing aircraft, especially large ones, carry out a controlled ditching in the open sea or when rotary wing aircraft do the same, an awareness of the Code will at least provide the pilots some understanding of the prevailing surface conditions. Rotary wing pilots know that they are much more likely to have to ditch their aircraft than fixed wing pilots because their Quick Reference Handbook (QRH) will contain a considerable number of drills with a requirement to ‘land immediately’, even whilst over the sea, if certain critical malfunction warnings are annunciated. For this reason, commercially operated rotary wing aircraft are likely to be fitted with floatation equipment, although their inherent instability when floating on the sea surface, caused by their high centre of gravity, means that they are unlikely to remain upright in higher sea states. The prevailing sea state will be also be relevant to the process of occupant evacuation from a ditched helicopter (or one which has sustained a survivable uncontrolled ‘water impact’) before any capsize occurs. Here are examples of a coastal and recreational marine forecast that contain both sea state and swell forecasts.In fluid dynamics, wind waves, or wind-generated waves, are water surface waves that occur on the free surface of the oceans and other bodies. They result from the wind blowing over an area of fluid surface. Waves in the oceans can travel thousands of miles before reaching land. Wind waves on Earth range in size from small ripples, to waves over 100 ft (30 m) high.

• In oceanography, sea state is the general condition of the free surface on a large body of water—with respect to wind waves and swell—at a certain location and moment. A sea state is characterized by statistics, including the wave height, period, and power spectrum. The sea state varies with time, as the wind conditions or swell conditions change. The sea state can either be assessed by an experienced observer, like a trained mariner, or through instruments like weather buoys, wave radar or remote sensing satellites.

5. What we call sea state is the effect that the local winds have on sea conditions – this is independent of travelling swell waves generated by winds outside of the local area. Sea state is related to the Beaufort scale which describes the state of the sea. The Beaufort wind force scale is an empirical measure that relates wind speed to observed conditions at sea. It was originally devised by an Irish Royal Navy officer, Francis Beaufort, in the early 19th century. In that time, naval officers made regular weather observations however without a standard scale, they were very subjective.  The Beaufort scale assisted in standardizing these observations. The scale has been adjusted and added to over the past 200 years, and while some countries use forces up to seventeen, the World Meteorological Organization recognises thirteen classes, from zero to twelve. Part of the modern Beaufort Scale is shown in figure two.

In the context of aviation, sea state may clearly be of significance to seaplanes and flying boats but for land based aircraft, the main relevance is to the controlled ditching of both fixed wing and rotary wing types. Where the latter are routinely operated over water, they are usually equipped with floatation devices which are designed, in up to a limiting sea state, to keep the aircraft upright to facilitate occupant evacuation. imdb-header__-state-node></div><div class=ipc-page-content-container ipc-page-content-container--center navbar__inner role=presentation><label aria-label=Open Navigation Drawer role..

By Karyn Wofford | May 11, 2020 Note that wind wave heights are significantly affected by local conditions, such as whether the wind is onshore or offshore and the fetch and its duration. New Zealand’s mountainous terrain also has a large influence on the wind flow – it can vary significantly around the next headland or in the lee of the next set of hills. The wind flow, in turn, affects the local sea conditions. An offshore wind blowing from the land onto the sea is usually smooth close to shore but noticeably rougher further out because it takes a little distance for the wind to work up waves on the sea surface.  It starts off generating small wavelets close to the land, then short steeper waves and then bigger less steep waves further out. On the other hand, onshore winds do not have this fetch limitation. Depending on the wind direction, the more sheltered areas of MetService forecast areas should not be as rough as exposed areas. When interpreting the sea state in a MetService forecast, the local conditions need to be taken into consideration.   California allows in-store shopping across state with approval by local county officials.

In mathematics, the Schur orthogonality relations, which is proven by Issai Schur through Schur's lemma, express a central fact about representations of finite groups. They admit a generalization to the case of compact groups in general, and in particular compact Lie groups, such as the rotation group SO(3).The Compton wavelength is a quantum mechanical property of a particle. It was introduced by Arthur Compton in his explanation of the scattering of photons by electrons. The Compton wavelength of a particle is equal to the wavelength of a photon whose energy is the same as the mass of that particle. Today's Port Douglas, Australia water temperature.

Among the various facilities of this property are an outdoor swimming pool and a fitness center In fluid dynamics, a cnoidal wave is a nonlinear and exact periodic wave solution of the Korteweg–de Vries equation. These solutions are in terms of the Jacobi elliptic function cn, which is why they are coined cnoidal waves. They are used to describe surface gravity waves of fairly long wavelength, as compared to the water depth. Sea Thalasso by Douglas is a Floral Woody Musk fragrance for women.

Widom scaling is a hypothesis in statistical mechanics regarding the free energy of a magnetic system near its critical point which leads to the critical exponents becoming no longer independent so that they can be parameterized in terms of two values. The hypothesis can be seen to arise as a natural consequence of the block-spin renormalization procedure, when the block size is chosen to be of the same size as the correlation length.

The sea, the world ocean or simply the ocean is the connected body of salty water that covers over 70% of Earth's surface. It moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. It has been travelled and explored since ancient times, while the scientific study of the sea—oceanography—dates broadly from the voyages of Captain James Cook to explore the Pacific Ocean between 1768 and 1779. The word sea is also used to denote smaller, partly landlocked sections of the ocean and certain large, entirely landlocked, saltwater lakes, such as the Caspian Sea and the Dead Sea.Swell refers to waves that develop over a longer period of time than locally-generated wind waves, and over a larger area. Swell waves (often just called swell) are self-sustaining and can travel long distances and usually originate hundreds or thousands of kilometres away from where they have an impact. Swell waves have longer periods (the time taken for waves to pass by) than wind waves and so affect craft differently.   Because no two waves (swell waves or wind waves) are exactly the same, swell height is described by: The Mediterranean Sea is already nearly dead; the North Sea is following it. The Aral Sea is on the brink of extinction. If nothing is done about it, one day nothing will be able to live in the seas

In physics, a wave vector is a vector which helps describe a wave. Like any vector, it has a magnitude and direction, both of which are important. Its magnitude is either the wavenumber or angular wavenumber of the wave, and its direction is ordinarily the direction of wave propagation. Find a park. By State..

The official Fujita scale category is determined by meteorologists and engineers after a ground or aerial damage survey, or both; and depending on the circumstances, ground-swirl patterns, weather radar data, witness testimonies, media reports and damage imagery, as well as photogrammetry or videogrammetry if motion picture recording is available. The Fujita scale was replaced with the Enhanced Fujita scale (EF-Scale) in the United States in February 2007. In April 2013, Canada adopted the EF-Scale over the Fujita scale along with 31 "Specific Damage Indicators" used by Environment Canada (EC) in their ratings. Sea state is related to the Beaufort scale which describes the state of the sea. The World Meteorological Organization and MetService use the Douglas Sea Scale to define sea state
