Cyclone Pam
Severe Tropical Cyclone Pam was the second most intense tropical cyclone of the South Pacific Ocean in terms of sustained winds and is regarded as one of the worst natural disasters in the history of Vanuatu. A total of 15–16 people lost their lives either directly or indirectly as a result of Pam with many others injured. The storm's impacts were also felt, albeit to a lesser extent, to other islands in the South Pacific, most notably the Solomon Islands, Tuvalu, and New Zealand. Pam is the third most intense storm of the South Pacific Ocean according to pressure, after Winston of 2016 and Zoe of 2002. It is also the second most intense tropical cyclone in 2015, only behind Hurricane Patricia. In addition, Pam is tied with Orson, Monica, Marcus and Fantala for having the second strongest ten-minute maximum sustained winds in the Southern Hemisphere. Thousands of homes, schools and buildings were damaged or destroyed, with an estimated 3,300 people displaced as a resu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuvalu
Tuvalu ( or ; formerly known as the Ellice Islands) is an island country and microstate in the Polynesian subregion of Oceania in the Pacific Ocean. Its islands are situated about midway between Hawaii and Australia. They lie east-northeast of the Santa Cruz Islands (which belong to the Solomon Islands), northeast of Vanuatu, southeast of Nauru, south of Kiribati, west of Tokelau, northwest of Samoa and Wallis and Futuna, and north of Fiji. Tuvalu is composed of three reef islands and six atolls. They are spread out between the latitude of 5° and 10° south and between the longitude of 176° and 180°. They lie west of the International Date Line. Tuvalu has a population of 10,507 (2017 census). The total land area of the islands of Tuvalu is . The first inhabitants of Tuvalu were Polynesians, according to well-established theories regarding a migration of Polynesians into the Pacific that began about three thousand years ago. Long before European contact with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hurricane Patricia
Hurricane Patricia was the strongest tropical cyclone on record worldwide in terms of wind speed and the second-most intense on record worldwide in terms of pressure, behind Typhoon Tip in 1979, with a minimum atmospheric pressure of 872 mbar (hPa; ). Originating from a sprawling disturbance near the Gulf of Tehuantepec, south of Mexico, in mid-October 2015, Patricia was first classified a tropical depression on October 20. Initial development was slow, with only modest strengthening within the first day of its classification. The system later became a tropical storm and was named Patricia, the twenty-fourth named storm of the annual hurricane season. Exceptionally favorable environmental conditions fueled explosive intensification on October 22. A well-defined eye developed within an intense central dense overcast and Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours—a near-record pace. On October 23, the hurricane a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Cruz Islands
The Santa Cruz Islands are a group of islands in the Pacific Ocean, part of Temotu Province of the nation of Solomon Islands discovered by the Spaniards. They lie approximately 250 miles (400 km) to the southeast of the Solomon Islands archipelago. The Santa Cruz Islands lie just north of the archipelago of Vanuatu, and are considered part of the Vanuatu rain forests ecoregion. Geography The term Santa Cruz Islands is sometimes used to encompass all of the islands of the present-day Solomon Islands province of Temotu. The largest island is Nendö, which is also known as Santa Cruz Island proper (505.5 km2, highest point , population over 5000). Lata, located on Nendö, is the largest town, and the capital of Temotu province. Other islands belonging to the Santa Cruz group are Vanikoro (173.2 km2, population 800, which is actually two islands, Banie and its small neighbor Teanu) and Utupua (69.0 km2, highest point , population 848). The Santa Cru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Of Emergency
A state of emergency is a situation in which a government is empowered to be able to put through policies that it would normally not be permitted to do, for the safety and protection of its citizens. A government can declare such a state during a natural disaster, civil unrest, armed conflict, medical pandemic or epidemic or other biosecurity risk. ''Justitium'' is its equivalent in Roman law—a concept in which the Roman Senate could put forward a final decree ('' senatus consultum ultimum'') that was not subject to dispute yet helped save lives in times of strife. Relationship with international law Under international law, rights and freedoms may be suspended during a state of emergency, depending on the severity of the emergency and a government's policies. Use and viewpoints Though fairly uncommon in democracies, dictatorial regimes often declare a state of emergency that is prolonged indefinitely for the life of the regime, or for extended periods of time ...

Storm Surge
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Other factors affecting storm surge severity include the shallowness and orientation of the water body in the storm path, the timing of tides, and the atmospheric pressure drop due to the storm. There is a suggestion that climate change may be increasing the hazard of storm surges. Some theorize that as extreme weather becomes more intense and sea level rises due to climate change, storm surge is expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, ... [...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. Th ...

Mbar
The bar is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa), or slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar). By the barometric formula, 1 bar is roughly the atmospheric pressure on Earth at an altitude of 111 metres at 15 °C. The bar and the millibar were introduced by the Norwegian meteorologist Vilhelm Bjerknes, who was a founder of the modern practice of weather forecasting. The International System of Units, despite previously mentioning the bar, now omits any mention of it.. The bar has been legally recognised in countries of the European Union since 2004. British Standard BS 350:2004 ''Conversion Factors for Units''. The US National Institute of Standards and Technology (NIST) deprecates its use except for "limited use in meteorology" and lists it as one of several units that "must not be introd ...

Tropical Cyclone Scales
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index. Tropical cyclones that develop in the Northern Hemisphere are unofficially classified by the warning centres on one of three intensity scales. Tropical cyclones or subtropical cyclones that exist within the North Atlantic Ocean or the North-eastern Pacific Ocean are classified as either tropical depressions or tropical storms. Should a system intensify further and become a hurricane, then it will be classified on the Saffir–Simpson hurricane wind scale, and is based on the estimated maximum sustained winds over a 1-min ...
