2023 Pacific Typhoon Season
The 2023 Pacific typhoon season was the fourth and final consecutive below-average season and became the third-most inactive typhoon season on record in terms of named storms, with just 17 named storms developing, only ahead of 2010 Pacific typhoon season, 2010 and 1998 Pacific typhoon season, 1998, however it had a slightly above average in terms of Accumulated Cyclone Energy, ACE. Despite the season occurring during an El Niño event, which typically favors activity in the basin, activity was abnormally low. This was primarily due to a consistent period of negative Pacific decadal oscillation, PDO, which typically discourages tropical storm formation in this basin. The season was less active than the 2023 Atlantic hurricane season in terms of named storms, the fourth such season on record, after 2005 Pacific typhoon season, 2005, 2010 Pacific typhoon season, 2010 and 2020 Pacific typhoon season, 2020. The season's number of storms also did not exceed that of the 2023 Pacific hur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhoon Mawar
Typhoon Mawar, known in the Philippines as Super Typhoon Betty, was one of the strongest Northern Hemisphere tropical cyclones on record in the month of May, and the strongest tropical cyclone Tropical cyclones in 2023, worldwide in 2023. The name "Mawar" means ''Rose'' in Indonesian language, Indonesia. The second named storm, the first typhoon and the first super typhoon of the 2023 Pacific typhoon season, Mawar originated from an area of low pressure south-southwest of Chuuk Lagoon that developed into a tropical depression on May 19. It fluctuated in intensity and became a tropical storm, after which it intensified into a Category 4-equivalent super typhoon on the Saffir–Simpson hurricane wind scale. It then underwent an eyewall replacement cycle, then reintensified to attain 1-minute sustained winds of according to the JTWC, becoming a Category 5-equivalent super typhoon. Mawar weakened slightly as it moved around the southwestern edge of the subtropical h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

180th Meridian
The 180th meridian or antimeridian is the meridian (geography), meridian 180° both east and west of the prime meridian in a Geographic coordinate system, geographical coordinate system. The longitude at this line can be given as either east or west. On Earth, the prime and 180th meridians form a great ellipse that divides the planet into the Western Hemisphere, Western and Eastern Hemispheres. Locations The antimeridian passes mostly through the open waters of the Pacific Ocean but also runs across land in Russia, Fiji, and Antarctica. An important function of this meridian is its use as the basis for the International Date Line, which snakes around national borders to maintain date consistency within the territories of Russia, the United States, Kiribati, Fiji and New Zealand. Starting at the North Pole of the Earth and heading south to the South Pole, the 180th meridian passes through: The meridian also passes between (but not particularly close to): *through the Aleu ...

100th Meridian East
The meridian 100° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Asia, the Indian Ocean, the Southern Ocean, and Antarctica to the South Pole. The 100th meridian east forms a great circle with the 80th meridian west. From Pole to Pole Starting at the North Pole and heading south to the South Pole The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface.

Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the equator. For other planets in the Solar System, north is defined by humans as being in the same celestial sphere, celestial hemisphere relative to the invariable plane of the Solar System as Earth's North Pole. Due to Earth's axial tilt of 23.439281°, there is a seasonal variation in the lengths of the day and night. There is also a seasonal variation in temperatures, which lags the variation in day and night. Conventionally, winter in the Northern Hemisphere is taken as the period from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer is taken as the period from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the Year#Astronomical years, astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that aff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone Naming
Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same Tropical cyclone basins, basin. Once storms develop sustained wind speeds of more than , names are generally assigned to them from predetermined lists, depending on the basin in which they originate. Some tropical depressions are named in the Western Pacific, while tropical cyclones must contain a significant amount of gale-force winds before they are named in the Southern Hemisphere. Before it became standard practice to give Given name, personal (first) names to tropical cyclones, they were named after places, objects, or the saints' feast days on which they occurred. Credit for the first usage of personal names for weather systems is generally given to Queensland Government meteorologist Clement Wr ...

Tropical Cyclogenesis
Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropics, tropical cyclogenesis occur are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm core, warm-core cyclone, due to significant convection in a favorable atmospheric environment. Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least ), atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low-pressure area, low-pressure center, a pre-existing low-level focus or disturbance, and low vertical wind shear. Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in tropical cyclone basins, most basins. Climate cycles such as ENSO and the Madden–Julian oscillation modulate the timing and frequency of tropical c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2002 Pacific Typhoon Season
The 2002 Pacific typhoon season was a slightly above average Pacific typhoon season, producing twenty-six named storms, fifteen becoming typhoons, and eight super typhoons. It had an ACE over 400 units, making it one of the most active seasons worldwide. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2002, though most tropical cyclones typically develop between May and November. The season's first named storm, Tapah, developed on January 11, while the season's last named storm, Pongsona, dissipated on December 11. The season's first typhoon, Mitag, reached typhoon status on March 1, and became the first super typhoon of the year four days later. The scope of this article is limited to the Pacific Ocean to the north of the equator between 100°E and 180th meridian. Within the northwestern Pacific Ocean, there are two agencies which assign names to tropical cyclones whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1976 Pacific Typhoon Season
The 1976 Pacific typhoon season has no official bounds; it ran year-round in 1976, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 1976 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Declaration Of Independence Of The Democratic Republic Of Vietnam
The declaration of independence of the Democratic Republic of Vietnam () was written by Hồ Chí Minh, and announced in public at the Ba Đình square in Hanoi on 2 September 1945. It led to the foundation of the Democratic Republic of Vietnam (DRV), replacing the Empire of Vietnam under the Nguyễn dynasty and Emperor Bảo Đại, who abdicated on August 25. This declaration was a declaration of independence from France, but France initially never recognized the DRV as an independent country. After the First Indochina War broke out; on 8 March 1949, France formed the independent and unified State of Vietnam (an associated state) with the Élysée Accords as an alternative method to solve the Vietnam question. The declaration is also considered the foundation of the Socialist Republic of Vietnam although this state was actually formed on 2 July 1976. History Vietnam, under the Nguyễn dynasty, became two protectorates of France in 1883, but during World War II, Japan occ ...
