Braer Storm Of January 1993
The Braer Storm was the most intense extratropical cyclone ever recorded over the northern Atlantic Ocean, as well as the strongest recorded worldwide. Developing as a weak frontal wave on 8 January 1993, the system moved rapidly northeast. The combination of the absorption of a second low-pressure area to its southeast, a stronger than normal sea surface temperature differential along its path, and the presence of a strong jet stream aloft led to a rapid strengthening of the storm, with its central pressure falling to an estimated on 10 January. Its strength was well predicted by forecasters in the United Kingdom, and warnings were issued before the low initially developed. Gale-force winds covered the far northern Atlantic between Western Europe and Atlantic Canada, due to the intensity of this storm, with hurricane-force winds confined near its centre of circulation. After reaching its peak intensity, the system weakened as it moved into the far northeast Atlantic, dissipati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extratropical Cyclone
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to severe gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone. Terminology The term " cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor ''extratropical'' signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude. They are term ...

Shetland Islands
Shetland, also called the Shetland Islands and formerly Zetland, is a subarctic archipelago in Scotland lying between Orkney, the Faroe Islands and Norway. It is the northernmost region of the United Kingdom. The islands lie about to the northeast of Orkney, from mainland Scotland and west of Norway. They form part of the border between the Atlantic Ocean to the west and the North Sea to the east. Their total area is ,Shetland Islands Council (2012) p. 4 and the population totalled 22,920 in 2019. The islands comprise the Shetland constituency of the Scottish Parliament. The local authority, the Shetland Islands Council, is one of the 32 council areas of Scotland. The islands' administrative centre and only burgh is Lerwick, which has been the capital of Shetland since 1708, before which time the capital was Scalloway. The archipelago has an oceanic climate, complex geology, rugged coastline, and many low, rolling hills. The largest island, known as " the Mainland", ha ...

Braer Storm 1993-01-11
The MV ''Braer'' was an oil tanker which ran aground during a storm off Shetland, Scotland, in January 1993, and nearly a week later broke up during the most intense extratropical cyclone on record for the northern Atlantic Ocean, the Braer Storm of January 1993. Design and history The MV ''Braer'' was originally launched as the ''Hellespoint Pride'' and was constructed by Oshima Shipbuilding Company in 1975. The Braer was originally owned by Tucana Shipping Company of Singapore before being purchased by the Hancock Shipping Company registered in Monrovia when she was renamed ''Brae Trader.'' She was named ''Braer'' when she was acquired by the Braer Corporation in 1990. Reason for ship's loss During the enquiry after the ship's loss, it was stated that the ship lost power due to seawater contamination of the ship's heavy fuel oil on 3 January. This occurred after a pipeline on the deck broke loose, allowing seawater to enter the vessel's bunker tanks via broken air vents. The l ...

Weather Buoy
Weather buoys are instruments which collect weather and ocean data within the world's oceans, as well as aid during emergency response to chemical spills, legal proceedings, and engineering design. Moored buoys have been in use since 1951, while drifting buoys have been used since 1979. Moored buoys are connected with the ocean bottom using either chains, nylon, or buoyant polypropylene. With the decline of the weather ship, they have taken a more primary role in measuring conditions over the open seas since the 1970s. During the 1980s and 1990s, a network of buoys in the central and eastern tropical Pacific Ocean helped study the El Niño-Southern Oscillation. Moored weather buoys range from in diameter, while drifting buoys are smaller, with diameters of . Drifting buoys are the dominant form of weather buoy in sheer number, with 1250 located worldwide. Wind data from buoys has smaller error than that from ships. There are differences in the values of sea surface temperatur ...

Weather Ship
A weather ship, or ocean station vessel, was a ship stationed in the ocean for surface and upper air meteorological observations for use in weather forecasting. They were primarily located in the north Atlantic and north Pacific oceans, reporting via radio. The vessels aided in search and rescue operations, supported transatlantic flights, acted as research platforms for oceanographers, monitored marine pollution, and aided weather forecasting by weather forecasters and in computerized atmospheric models. Research vessels remain heavily used in oceanography, including physical oceanography and the integration of meteorological and climatological data in Earth system science. The idea of a stationary weather ship was proposed as early as 1921 by Météo-France to help support shipping and the coming of transatlantic aviation. They were used during World War II but had no means of defense, which led to the loss of several ships and many lives. On the whole, the establishment of wea ...
