NationMaster - Encyclopedia: Cyclone Gonu

Cyclone Gonu (JTWC designation: 02A, also known as Super Cyclonic Storm Gonu) is the strongest tropical cyclone on record in the Arabian Sea, and tied for the strongest tropical cyclone on record in the northern Indian Ocean.^[1] The second named tropical cyclone of the 2007 North Indian Ocean cyclone season, Gonu developed from a persistent area of convection in the eastern Arabian Sea on June 1. With a favorable upper-level environment and warm sea surface temperatures, it rapidly intensified to attain peak 10-min winds of 240 km/h (150 mph) on June 3, as warned by the India Meteorological Department. Intense cyclones like Gonu have been rare over the Arabian Sea, as most storms in this area tend to be small and dissipate quickly.^[2] Image File history File links Lightning_NOAA.jpgâ€Ž Description: Multiple cloud-to-ground and cloud-to-cloud lightning strokes during night-time. ...

Storm history

On May 27, a widespread area of convection persisted over the southeastern Arabian Sea.^[3] By May 31, an organized tropical disturbance developed about 645 km (400 mi) south of Mumbai, India with cyclonic convection and a well-defined mid-level circulation. The disturbance initially lacked a distinct low-level circulation; instead it consisted of strong divergence along the western end of a surface trough of low pressure.^[4] A propitious upper-level environment allowed convection to improve, and on June 1 a low-level circulation formed.^[5] By late on June 1, the system developed to the extent that the India Meteorological Department (IMD) classified it a depression.^[6] It tracked westward along the southwestern periphery of a mid-level ridge over southern India; convection continued to organize, and early on June 2 the Joint Typhoon Warning Center (JTWC) classified it Tropical Cyclone 02A while it was located about 685 km (425 mi) southwest of Mumbai, India.^[7] May 27 is the 147th day of the year (148th in leap years) in the Gregorian calendar. ...

Upon first forming, the system contended with the entrainment of dry air to the northwest of the storm; this was expected to limit intensification.^[7] The storm steadily intensified; early on June 2 the IMD upgraded it to deep depression status,^[8] and later in the day the IMD classified the system as Cyclonic Storm Gonu while it was located 760 km (470 mi) southwest of Mumbai, India.^[9] As a mid-latitude trough developed over Pakistan, Gonu turned to the north and northeast,^[10] though resumed a westward track after ridging built to the north of the storm.^[11] With a solid area of intense convection, it rapidly intensified to attain severe cyclonic status early on June 3,^[12] and with good outflow the JTWC upgraded it to the equivalent of a Category 1 tropical cyclone.^[13] The dry air ultimately had a smaller impact on the intensification than previously estimated. As the storm tracked under an upper-level ridge axis, outflow increased further, and combined with a local increase in ocean heat content, Gonu rapidly deepened and developed a well-defined eye in the center of convection.^[14] June 2 is the 153rd day of the year (154th in leap years) in the Gregorian calendar. ...

Late on June 3, the IMD classified the storm as Very Severe Cyclonic Storm Gonu,^[15] upon which it became the most intense cyclone on record in the Arabian Sea.^[1] With low amounts of vertical wind shear and favorable upper-level outflow, Gonu strengthened further to attain peak 1-min sustained winds of 260 km/h (160 mph) and gusts to 315 km/h (195 mph) while located about 285 km (175 miles) east-southeast of Masirah Island on the coast of Oman.^[16] At that intensity, Gonu was tied for the strongest tropical cyclone in the northern Indian Ocean.^[1] the IMD upgraded it to Super Cyclonic Storm Gonu late on June 4, with 10-min sustained winds reaching 240 km/h (150 mph) and an estimated pressure of 920 mbar.^[17] June 3 is the 154th day of the year (155th in leap years) in the Gregorian calendar. ...

After maintaining peak winds for about 9 hours, the IMD downgraded Gonu to very severe cyclonic storm status early on June 5.^[18] Its eye became cloud-filled and ragged, and the cyclone gradually weakened as it continued tracking northwestward over cooler water temperatures and through drier air.^[19] June 5 is the 156th day of the year (157th in leap years) in the Gregorian calendar. ...

Preparations

The Oman Chairman of the National Committee for Civil Defence remarked the nation had already developed a contingency plan, which included the activation of army and police personnel after the storm's passage. Significant damage was expected, especially in northeastern areas, along with up to 150 mm (6 in) of rainfall and very strong winds.^[20] Officials recommended citizens to evacuate from potentially affected areas,^[21] and about 7,000 people forced to leave Masirah Island due to the threat for high surf and strong winds.^[22] A state of emergency was declared for the nation.^[21] The national weather service in Oman warned that the cyclone was expected to be worse than the destructive cyclone which hit Masirah Island in 1977. The Mina al Fahal oil terminal was expected to be shut down once the cyclone hits. The country's Sur export terminal, which handles natural gas exports, was also closed.^[23] A millimetre (American spelling: millimeter, symbol mm) is an SI unit of length that is equal to one thousandth of a metre. ...

In Saudi Arabia and the United Arab Emirates, both members of OPEC, no official warnings had been issued on Gonu. The storm was not expected to disrupt oil supplies from these two nations.^[21] Due to the threat of the cyclone disrupting oil shipments, crude oil prices increased to over US$70 per barrel.^[24] OPEC Logo The Organization of the Petroleum Exporting Countries (OPEC) is an international organization made up of Iraq, Indonesia, Iran, Kuwait, Libya, Angola, Algeria, Nigeria, Qatar, Saudi Arabia, the United Arab Emirates, and Venezuela. ...

Energy

Oil prices rose early Tuesday because of concerns about disruptions caused by Gonu and the threat of further strikes in Nigeria, Africa's biggest producer. Crude oil for July delivery rose $1.13, or 1.7 percent, to $66.21 Monday on the New York Mercantile Exchange, the highest close since May 21. Futures touched $66.48, the highest intraday price since April 30. The contract was at $65.95 a barrel, down 26 cents, in after-hours electronic trading at 9:43 a.m. Tuesday in Singapore.^[29] But Tom Kloza, chief oil analyst at the Oil Price Information Service, said he doubted the increase could really be attributed to Gonu. "I don't know if you can really attribute any of the gain to the cyclone," he said. "It's an excuse, as opposed to a reason, for the rise in prices."^[30] The New York Mercantile Exchange**** NOTE the AMENX is FAKE, created by york-commodities to scam your money, if you send money you will never see it again**** You have been warned. ...
