Hurricane Ana (2014)
Hurricane Ana was the second tropical cyclone in 2014 to threaten the U.S. state of Hawaii with a direct hit, after Iselle in August. The twenty-first named storm and fifteenth hurricane of the 2014 Pacific hurricane season, Ana formed from a disturbance that formed in the Central Pacific in mid-October. It rapidly consolidated, and a tropical depression developed by October 13. Aided by favorable conditions, Ana gradually strengthened while moving westward, threatening to pass over the island chain of Hawaii once or several times as indicated by early forecasts. By October 17, it had strengthened to a hurricane south of Hawaii and reached its peak intensity shortly afterwards while also making its closest approach. Afterwards, Ana weakened and began to fluctuate in intensity as it turned to the north and eventually northeast as it rounded a subtropical ridge and interacted with a cold front before becoming a hurricane briefly again on October 25.

Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected ...

Subtropical Ridge
The horse latitudes are the latitudes about 30 degrees north and south of the Equator. They are characterized by sunny skies, calm winds, and very little precipitation. They are also known as Subtropics, subtropical ridges, or highs. It is a high-pressure area at the divergence of trade winds and the westerlies. Origin of the term A likely and documented explanation is that the term is derived from the "dead horse" ritual of seamen (see Flogging a dead horse#Earlier meaning, Beating a dead horse). In this practice, the seaman paraded a straw-stuffed effigy of a horse around the deck before throwing it overboard. Seamen were paid partly in advance before a long voyage, and they frequently spent their pay all at once, resulting in a period of time without income. If they got advances from the ship's paymaster, they would incur debt. This period was called the "dead horse" time, and it usually lasted a month or two. The seaman's ceremony was to celebrate having worked off the "d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vegetation
Vegetation is an assemblage of plant species and the ground cover they provide. It is a general term, without specific reference to particular taxa, life forms, structure, spatial extent, or any other specific botanical or geographic characteristics. It is broader than the term ''flora'' which refers to species composition. Perhaps the closest synonym is plant community, but ''vegetation'' can, and often does, refer to a wider range of spatial scales than that term does, including scales as large as the global. Primeval redwood forests, coastal mangrove stands, sphagnum bogs, desert soil crusts, roadside weed patches, wheat fields, cultivated gardens and lawns; all are encompassed by the term ''vegetation''. The vegetation type is defined by characteristic dominant species, or a common aspect of the assemblage, such as an elevation range or environmental commonality. The contemporary use of ''vegetation'' approximates that of ecologist Frederic Clements' term earth cover, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Ana Passing By - Saturday 10-18 (15894565002)
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling roun ...

Honolulu Harbor
Honolulu Harbor, also called ''Kulolia'' and ''Ke Awa O Kou'' and the Port of Honolulu , is the principal seaport of Honolulu and the State of Hawaii in the United States. From the harbor, the City & County of Honolulu was developed and urbanized, in an outward fashion, over the course of the modern history of the island of Oahu. It includes Matson, Inc. harbors on Sand Island. History Archaeological surveys show that the area around Honolulu Harbor was bustling with human activity prior to 1100. The first European vessel to enter Honolulu Harbor was a long-boat from the British merchant ship ''King George''. The boat rowed into the harbor on December 12, 1786, commanded by a Mr. Hayward and piloted by Towanooha, servant of a friendly Hawaiian priest. In 1794, ''Butterworth'', a British ship commanded by Captain William Brown, entered the harbor by "warping" in. The crew dubbed it "Brown's Harbor" to their captain's dismay. Captain Brown insisted that the harbor be called "Fair ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand Island (Hawaii)
Sand Island, formerly known as Quarantine Island, is a small island within the city of Honolulu, Hawaii, United States. The island lies at the entrance to Honolulu Harbor. History The island was known as Quarantine Island during the 19th century, when it was used to quarantine ships believed to carry contagious passengers. During World War II, Sand Island was used as an Army internment camp to house Japanese Americans as well as expatriates from Germany, Italy, and other Axis countries living in Hawaii. The camp opened in December 1941, soon after the Japanese attack on Pearl Harbor and the subsequent mass arrests of civilians accused—often without evidence—of espionage or other fifth column activity. Over 600 Hawaiian residents, many of them U.S. citizens, would pass through Sand Island before it was closed in March 1943. Most of the internees had been transferred to Army and Department of Justice internment camps on the mainland beginning in February 194 ...

Niihau
Niihau ( Hawaiian: ), anglicized as Niihau ( ), is the westernmost main and seventh largest inhabited island in Hawaii. It is southwest of Kauaʻi across the Kaulakahi Channel. Its area is . Several intermittent playa lakes provide wetland habitats for the Hawaiian coot, the Hawaiian stilt, and the Hawaiian duck. The island is designated as critical habitat for ''Brighamia insignis'', an endemic and endangered species of Hawaiian lobelioid. The United States Census Bureau defines Niihau and the neighboring island and State Seabird Sanctuary of Lehua as Census Tract 410 of Kauai County, Hawaii.

Tropical Cyclone Warnings And Watches
Tropical cyclone warnings and watches are alerts issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including evacuation of vulnerable areas where necessary. It is important that interests throughout the area of an alert make preparations to protect life and property, and do not disregard it on the strength of the detailed forecast track. Western hemisphere New tropical cyclone position and forecast information is available at least every twelve hours in the Southern Hemisphere and at least every six hours in the Northern Hemisphere from Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers. In conjunction with the National Hurricane Center, the national meteorological and hydrological services of Central America, the northern Atlan ...

Wind Shear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
