Typhoon Ivan
Typhoon Ivan, known in the Philippines as Typhoon Narsing, was an intense tropical cyclone that existed simultaneously with another storm of the same intensity, Typhoon Joan, in October 1997. Forming out of an area of disturbed weather on October 13, Ivan gradually intensified into a typhoon as it tracked steadily to the west-northwest. On October 15, the storm underwent rapid intensification and reached an intensity corresponding to Category 5 status on the Saffir–Simpson Hurricane Scale. Late on October 17, Ivan reached its peak strength with winds of 295 km/h (185 mph) and a barometric pressure of 905 hPa (mbar). Shortly thereafter, the typhoon began to weaken as it approached the Philippines. Ivan eventually made landfall in northern Luzon with winds of 220 km/h (140 mph) on October 20 before weakening to a tropical storm the next day. The storm then curved northeastward and became extratropical on October 25 and dissipatin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshall Islands
The Marshall Islands ( mh, Ṃajeḷ), officially the Republic of the Marshall Islands ( mh, Aolepān Aorōkin Ṃajeḷ),'' () is an independent island country and microstate near the Equator in the Pacific Ocean, slightly west of the International Date Line. Geographically, the country is part of the larger island group of Micronesia. The country's population of 58,413 people (at the 2018 World Bank Census) is spread out over five islands and 29 coral atolls, comprising 1,156 individual islands and islets. The capital and largest city is Majuro. It has the largest portion of its territory composed of water of any sovereign state, at 97.87%. The islands share maritime boundaries with Wake Island to the north, Kiribati to the southeast, Nauru to the south, and Federated States of Micronesia to the west. About 52.3% of Marshall Islanders (27,797 at the 2011 Census) live on Majuro. In 2016, 73.3% of the population were defined as being "urban". The UN also indicates a population d ...

Atmospheric Convection
Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. Overview There are a few general archetypes of atmospheric instability that are used to explain convection (or lack thereof). A necessary (but not sufficient) condition for convection is that the environmental lapse rate (the rate of decrease of temperature with height) is steeper than the lapse rate experienced by a rising parcel of air. When this condition is met, upward-displaced air parcels can become buoyant and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cagayan

Ivan & Joan 1997-10-17 0700Z
Ivan () is a Slavic male given name, connected with the variant of the Greek name (English: John) from Hebrew meaning 'God is gracious'. It is associated worldwide with Slavic countries. The earliest person known to bear the name was Bulgarian tsar Ivan Vladislav. It is very popular in Russia, Ukraine, Croatia, Serbia, Bosnia and Herzegovina, Slovenia, Bulgaria, Belarus, North Macedonia, and Montenegro and has also become more popular in Romance-speaking countries since the 20th century. Etymology Ivan is the common Slavic Latin spelling, while Cyrillic spelling is two-fold: in Bulgarian, Russian, Macedonian, Serbian and Montenegrin it is Иван, while in Belarusian and Ukrainian it is Іван. The Old Church Slavonic (or Old Cyrillic) spelling is . It is the Slavic relative of the Latin name , corresponding to English ''John''. This Slavic version of the name originates from New Testament Greek (''Iōánnēs'') rather than from the Latin . The Greek name is in turn ...

Luzon Strait
The Luzon Strait (Tagalog: ''Kipot ng Luzon'', ) is the strait between Taiwan and Luzon island of the Philippines. The strait thereby connects the Philippine Sea to the South China Sea in the western Pacific Ocean. This body of water is an important strait for shipping and communications. Many ships from the Americas use this route to go to important East Asian ports. Many submarine communications cables pass through the Luzon Strait. These cables provide important data and telephony services to mainland China, Hong Kong, Taiwan, Japan and South Korea. Description The Luzon Strait is approximately wide containing a number of islands belonging to the Philippines that are grouped into two: the islands comprising the province of Batanes and the Babuyan Islands, which are part of the province of Cagayan. The strait is divided into a number of smaller channels. The Babuyan Channel separates Luzon from the Babuyan Islands, which is separated from Batanes by the Balintang Chann ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Zeb
Typhoon Zeb, known in the Philippines as Typhoon Iliang, was a powerful typhoon that struck the island of Luzon in October 1998. It is tied with Cyclone Ron and Cyclone Susan in terms of minimum pressure, for the most intense tropical cyclone worldwide for 1998. The tenth tropical storm of the season, Zeb formed on October 10 from the monsoon trough near the Caroline Islands. It moved westward initially and quickly intensified. Zeb's inflow briefly spawned another tropical storm, which it ultimately absorbed. Developing an eye, Zeb rapidly intensified into a super typhoon, officially reaching maximum sustained winds of 205 km/h (125 mph); one warning agency estimated winds as high as 285 km/h (180 mph). After reaching peak intensity, the typhoon struck northern Luzon and quickly weakened over land. Turning to the north, Zeb brushed the east coast of Taiwan at a reduced intensity, and after accelerating to the northeast it moved through Japan. It became e ...

Typhoon Keith
Typhoon Keith was the tenth of a record eleven super typhoons to develop during the unusually intense 1997 Pacific typhoon season. Originating from a near-equatorial trough on October 26, the precursor depression to Keith slowly organized into a tropical storm. After two days of gradual strengthening, the storm underwent a period of rapid intensification on October 30 as winds increased to . On November 1, the storm further intensified into a super typhoon and later attained peak winds of . The following day, the powerful storm passed between Rota and Tinian in the Northern Mariana Islands. After fluctuating in strength over the following few days, a steady weakening trend established itself by November 5 as the typhoon accelerated towards the northeast. On October 8, Keith transitioned into an extratropical cyclone and was last noted early the following day near the International Dateline. Despite Typhoon Keith's close passage to the islands of Rota and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Angela (1995)
Typhoon Angela, known in the Philippines as Typhoon Rosing, was a catastrophic Category 5-equivalent typhoon with sustained winds, and the most intense tropical cyclone worldwide in 1995. Typhoon Angela was the third storm in a row that struck the Philippines, following Yvette and Zack. Typhoon Angela was the twenty-ninth tropical cyclone, and the fifth super typhoon of the moderately active 1995 Pacific typhoon season. Angela caused PHP 9.33 billion worth of damage across the Philippines, in addition to 882 fatalities. It was the strongest typhoon to hit the Philippines in 25 years, and the costliest in 5 years. Meteorological History The monsoon trough that developed Yvette and Zack spawned another tropical depression on October 25 in conjunction with a tropical disturbance that originated in the Marshall Islands. It moved to the west, organizing very slowly to become a tropical storm on October 26. Two days later Angela became a typhoon, and from the Octobe ...

Typhoon Gay (1992)
Typhoon Gay, known in the Philippines as Typhoon Seniang, was the strongest and longest-lasting storm of the 1992 Pacific typhoon season and most intense globally in 1992. It formed on November 14 near the International Date Line from a monsoon trough, which also spawned two other systems. Typhoon Gay later moved through the Marshall Islands as an intensifying typhoon, and after passing through the country it reached its peak intensity over open waters. The Joint Typhoon Warning Center (JTWC) estimated peak winds of 295 km/h (185 mph) and a minimum barometric pressure of . However, the Japan Meteorological Agency (JMA), which is the official warning center in the western Pacific, estimated winds of 205 km/h (125 mph), with a pressure of . Gay weakened rapidly after peaking because of interaction with another typhoon, and it struck Guam with winds of 160 km/h (100 mph) on November 23. The typhoon briefly re-intensified before weakening and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Joan
Typhoon Joan, known in the Philippines as Super Typhoon Sening, was the first of two super typhoons to strike the Philippines within a week in October 1970, the second being Super Typhoon Kate. Super Typhoon Joan is the fourth strongest typhoon ever to affect the Philippines, just after typhoons Haiyan, Meranti, and Goni. Meteorological history A tropical disturbance was first detected on October 8 near Truk (now Chuuk) and Ponape (now Pohnpei). Due to the wind and sea conditions, the disturbance moved west quicker than expected at near 17 knots (31 km/h or 20 mph). A circulation developed on the morning of October 9, and it was a tropical storm by the time it passed Ulithi Atoll. Joan continued to strengthen, and by October 11 had become a typhoon. However, it had slowed in forward speed due to it moving near an anticyclone that was located 300 miles (480 km) southeast of Okinawa. As Joan continued to strengthen, it reacted to the ridge line, and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainband
A rainband is a cloud and precipitation structure associated with an area of rainfall which is significantly elongated. Rainbands can be stratiform or convective, and are generated by differences in temperature. When noted on weather radar imagery, this precipitation elongation is referred to as banded structure. Rainbands within tropical cyclones are curved in orientation. Rainbands of tropical cyclones contain showers and thunderstorms that, together with the eyewall and the eye, constitute a hurricane or tropical storm. The extent of rainbands around a tropical cyclone can help determine the cyclone's intensity. Rainbands spawned near and ahead of cold fronts can be squall lines which are able to produce tornadoes. Rainbands associated with cold fronts can be warped by mountain barriers perpendicular to the front's orientation due to the formation of a low-level barrier jet. Bands of thunderstorms can form with sea breeze and land breeze boundaries, if enough moisture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
