Typhoon Melor
Typhoon Melor, known in the Philippines as Typhoon Nona, was a powerful tropical cyclone that struck the Philippines in December 2015. The twenty-seventh named storm and the eighteenth typhoon of the annual typhoon season, Melor killed 51 people and caused ₱7.04 billion (US$148.3 million) in damage. The typhoon began developing on December 7 as a low-pressure area of Chuuk. Soon, it intensified into a tropical depression on December 10, and then into a tropical storm south of Yap, and was named Melor. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAG-ASA) initially decided to name Melor as "Nonoy", but due to political reasons, it was named "Nona" instead. On December 13, Tropical Storm Melor (Nona) became a typhoon, and made its first landfall on Northern Samar. The typhoon made several landfalls in Sorsogon, Burias Island, Romblon, and Oriental Mindoro, before weakening into a tropical storm. It turned southward on entering the South Ch ...

Samar
Samar ( ) is the third-largest and seventh-most populous island in the Philippines, with a total population of 1,909,537 as of the 2020 census. It is located in the eastern Visayas, which are in the central Philippines. The island is divided into three provinces: Samar (formerly Western Samar), Northern Samar, and Eastern Samar. These three provinces, along with the provinces on the nearby islands of Leyte and Biliran, are part of the Eastern Visayas region. About a third of the island of Samar is protected as a natural park, known as the Samar Island Natural Park. On June 19, 1965, through Republic Act No. 4221, Samar was divided into three provinces: Northern Samar, (Western) Samar and Eastern Samar. The capitals of these provinces are, respectively, Catarman, Catbalogan City, and Borongan City. In commemoration of the establishment of these provinces, June 19 is celebrated as an annual holiday and many have the day off from work. Geography Samar is the third-largest ...

Joint Typhoon Warning Center
The Joint typhoon Warning Center (JTWC) is a joint United States Navy – United States Air Force command in Pearl Harbor, Hawaii. The JTWC is responsible for the issuing of tropical cyclone warnings in the North-West Pacific Ocean, South Pacific Ocean, and Indian Ocean for all branches of the U.S. Department of Defense and other U.S. government agencies. Their warnings are intended for the protection of primarily military ships and aircraft as well as military installations jointly operated with other countries around the world. Its U.S. Navy components are aligned with the Naval Meteorology and Oceanography Command. History The origins of the Joint Typhoon Warning Center (JTWC) can be traced back to June 1945, when the Fleet Weather Center/Typhoon Tracking Center was established on the island of Guam, after multiple typhoons, including Typhoon Cobra of December 1944 and Typhoon Connie in June 1945, had caused a significant loss of men and ships. At this time the center ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philippine Standard Time
Philippine Standard Time (PST or PhST; fil, Pamantayang Oras ng Pilipinas), also known as Philippine Time (PHT), is the official name for the time zone used in the Philippines. The country only uses one time zone, at an offset of UTC+08:00, but has used daylight saving time for brief periods in the 20th century. Geographic details Geographically, the Philippines lies and 126°34′ east of the Prime Meridian, and is physically located within the UTC+08:00 time zone. Philippine Standard Time is maintained by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). The Philippines shares the same time zone with China, Taiwan, Hong Kong, Macau, Malaysia, Singapore, Western Australia, Brunei, Irkutsk, Central Indonesia, and most of Mongolia. History Philippine Standard Time was instituted through Batas Pambansa Blg. 8 (that defined the metric system), approved on December 2, 1978, and implemented on January 1, 1983.

Laoang, Northern Samar
Laoang, officially the Municipality of Laoang ( war, Bungto han Laoang; tl, Bayan ng Laoang), is a 2nd class municipality in the province of Northern Samar, Philippines. According to the 2020 census, it has a population of 61,607 people. It is the economic, educational, socio-cultural and government center of the 2nd district of the province. History Pre-Spanish Time Written by: Rev.Msgr. Gaspar D. Balerite, H.P.S.Th.D., Vicar General-Diocese of Catarman In the pre-Hispanic times, the poblacion of Laoang was a settlement called Makarato while the whole island was called Lawang which later on evolved into Laoang. According to Fr. Ignatius Alzina in his book ''Historia de las Islas y Indios de Bisayas'', the settlement was ruled by a monarch called Dato Karagrag, whose consort Bingi had an irresistible beauty that captivated other neighbouring kings, especially the dato from Albay. (Fr. Alzina lived as missionary in Samar and Leyte for 38 years, from 1634 to 1674, working mostl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batag Island Lighthouse
Batag Island Lighthouse is a historic lighthouse on Batag Island off the coast of the town of Laoang in the province of Northern Samar in the Philippines. The light marks the northeastern point of Samar Island and led international ships to the entrance of the San Bernardino Strait marked by the San Bernardino Light. One of the most traveled waterways in the archipelago, together with the Capul Island Light, these stations are invaluable to vessels coming from the Pacific Ocean and entering the country through the San Bernardino Strait on its way to Manila or any other ports of the Philippines. After Maniguin Island and Cape Bolinao Lighthouse, this is the third major lighthouse wholly designed and built by the Americans in the early part of American Colonial Period in the Philippines. It was the exact duplicate of the Cape Bolinao lighthouse when it was completed, both standing at 101 ft (30.8m) and both equipped with third-order lights.K.S. Heck, A.S.C.E. "Port Works a ...

Landfall (meteorology)
Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there. Tropical cyclone A tropical cyclone is classified as making landfall when the center of the storm moves across the coast; in a relatively strong tropical cyclone, this is when the eye moves over land. This is where most of the damage occurs within a mature tropical cyclone, such as a typhoon or hurricane, as most of the damaging aspects of these systems are concentrated near the eyewall. Such effects include the peaking of the storm surge, the core of strong winds coming ashore, and heavy flooding rains. These coupled with high surf can cause major beach erosion. When a tropical cyclone makes landfall, the eye usually closes in upon itself due to negative environmental factors over land, such as friction with th ...

Aleutian Low
The Aleutian Low is a semi-permanent low-pressure system located near the Aleutian Islands in the Bering Sea during the Northern Hemisphere winter. It is a climatic feature centered near the Aleutian Islands measured based on mean sea-level pressure. It is one of the largest atmospheric circulation patterns in the Northern Hemisphere and represents one of the "main centers of action in atmospheric circulation." Classification The Aleutian Low is characterized by heavily influencing the path and strength of cyclones. Extratropical cyclones which form in the sub-polar latitudes in the North Pacific typically slow down and reach maximum intensity in the area of the Aleutian Low. Tropical cyclones that form in the tropical and equatorial regions of the Pacific can veer northward and get caught in the Aleutian Low. This is usually seen in the later summer months. Both the November 2011 Bering Sea cyclone and the November 2014 Bering Sea cyclone were post-tropical cyclones that had di ...

Outflow (meteorology)
Outflow, in meteorology, is air that flows outwards from a storm system. It is associated with ridging, or anticyclonic flow. In the low levels of the troposphere, outflow radiates from thunderstorms in the form of a wedge of rain-cooled air, which is visible as a thin rope-like cloud on weather satellite imagery or a fine line on weather radar imagery. For observers on the ground, a thunderstorm outflow boundary often approaches in otherwise clear skies as a low, thick cloud that brings with it a gust front. Low-level outflow boundaries can disrupt the center of small tropical cyclones. However, outflow aloft is essential for the strengthening of a tropical cyclone. If this outflow is restricted or undercut, the tropical cyclone weakens. If two tropical cyclones are in close proximity, the upper-level outflow from the upwind system can limit the development of the other system. Thunderstorms For thunderstorms, outflow tends to indicate the development of a system. Large quan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celsius
The degree Celsius is the unit of temperature on the Celsius scale (originally known as the centigrade scale outside Sweden), one of two temperature scales used in the International System of Units (SI), the other being the Kelvin scale. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale or a unit to indicate a difference or range between two temperatures. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale in 1742. Before being renamed in 1948 to honour Anders Celsius, the unit was called ''centigrade'', from the Latin ''centum'', which means 100, and ''gradus'', which means steps. Most major countries use this scale; the other major scale, Fahrenheit, is still used in the United States, some island territories, and Liberia. The Kelvin scale is of use in the sciences, with representing absolute zero. Since 1743 the Celsius scale has been based on 0 °C for the freezing ...

Sea Surface Temperature
Sea surface temperature (SST), or ocean surface temperature, is the ocean temperature close to the surface. The exact meaning of ''surface'' varies according to the measurement method used, but it is between and below the sea surface. Air masses in the Earth's atmosphere are highly modified by sea surface temperatures within a short distance of the shore. Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass. Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth's oceans. Tropical cyclones can also cause a cool wake, due to turbulent mixing of the upper of the ocean. SST changes diurnally, like the air above it, but to a lesser degree. There is less SST variation on breezy days than on calm days. In addition, ocean currents such as the Atlantic Multidecadal Oscillation (AMO), can affect SST's on multi-decadal time scales, a major impact results from the global thermohaline ci ...

Eye (cyclone)
The eye is a region of mostly calm weather at the center of tropical cyclones. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the ''eyewall'', a ring of towering thunderstorms where the most severe weather and highest winds occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is the location of the storm's minimum barometric pressure—where the atmospheric pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
