Typhoon Clara (1981)
Typhoon Clara, known in the Philippines as Typhoon Rubing, left flooding in the northern Philippines and southern China during September 1981. An area of disturbed weather was first detected on September 11 near Ponape. After moving westward, the system gradually became better organized and thunderstorm activity increased. On September 16, the system attained tropical storm status. Two days later, Clara attained typhoon intensity and subsequently began to deepen at a faster rate. On September 19, Clara reached maximum intensity, before making landfall along the northern tip of Luzon. Clara steadily weakened after interacting with land, but by late on September 20, Clara leveled off in intensity over the South China Sea. The next day, Clara moved ashore to the east-northeast of Hong Kong while still at typhoon intensity before rapidly dissipating over land. In the Philippines, 55 people perished. A total of 7,125 homes were damaged and 1,195 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maximum Sustained Wind
The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a distance defined as the radius of maximum wind, or RMW. Unlike gusts, the value of these winds are determined via their sampling and averaging the sampled results over a period of time. Wind measuring has been standardized globally to reflect the winds at above the Earth's surface, and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ten-minute time span (see the definition, below), anywhere within the tropical cyclone. Surface winds are highly variable due to friction between the atmosphere and the Earth's surface, as well as near hills and mountains over land. Over the ocean, satellite imagery determines the value of the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, and radar imagery can ...

Baguio
Baguio ( , ), officially the City of Baguio ( ilo, Siudad ti Baguio; fil, Lungsod ng Baguio), is a 1st class highly urbanized city in the Cordillera Administrative Region, Philippines. It is known as the "Summer Capital of the Philippines", owing to its cool climate since the city is located approximately above mean sea level, often cited as in the Luzon tropical pine forests ecoregion, which also makes it conducive for the growth of mossy plants, orchids and pine trees, to which it attributes its other moniker as the "City of Pines". Baguio was established as a hill station by the United States in 1900 at the site of an Ibaloi village known as ''Kafagway''. It was the United States' only hill station in Asia. Baguio is classified as a Highly-Urbanized City (HUC). It is geographically located within Benguet, serving as the provincial capital from 1901 to 1916, but has since been administered independently from the province following its conversion into a chartered cit ...

Shanwei
Shanwei (), or Swabue is a prefecture-level city in eastern Guangdong province, People's Republic of China. It borders Jieyang to the east, Meizhou and Heyuan to the north, Huizhou to the west, and looks out to the South China Sea to the south. It lies approximately east of Shenzhen and the locals speak the Haifeng dialect. History Shanwei City was established in 1988. It was politically administered as part of Huizhoufu (惠州府) by the Ming and Qing empires, Shanwei it gained its prefectural and administrative independence from Huizhou during the Nationalist period. The dominant ethnic population is Hoklo who came as a result of the large decrease in population caused by warfare in the early Qing dynasty in what is now Shanwei. Administration The prefecture-level city of Shanwei administers 4 county-level divisions, including 1 district, 1 county-level city and 2 counties. These are further divided into 53 township-level divisions, including 40 towns, 10 townships and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calayan, Cagayan
Calayan, officially the Municipality of Calayan ( ilo, Ili ti Calayan; tl, Bayan ng Calayan), is a 3rd class municipality in the province of Cagayan, Philippines. According to the 2020 census, it has a population of 17,410 people. Calayan is home to the Calayan rail, a flightless bird identified as a separate species in 2004 and endemic to Calayan Island.

Barometric Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 millibars, 760mm Hg, 29.9212 inchesHg, or 14.696psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the Earth's gravi ...

Rapid Deepening
In meteorology, rapid intensification is a situation where a tropical cyclone intensifies dramatically in a short period of time. The United States National Hurricane Center defines rapid intensification as an increase in the maximum sustained winds of a tropical cyclone of at least in a 24-hour period. Necessary conditions External In order for rapid intensification to occur, several conditions must be in place. Water temperatures must be extremely warm (near or above ), and water of this temperature must be sufficiently deep such that waves do not churn deeper cooler waters up to the surface. Wind shear must be low; when wind shear is high, the convection and circulation in the cyclone will be disrupted. Dry air can also limit the strengthening of tropical cyclones. Internal Usually, an anticyclone in the upper layers of the troposphere above the storm must also be present for extremely low surface pressures to develop. This is because air must be converging towards the low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Ridge (meteorology)
A ridge or barometric ridge is a term in meteorology describing an elongated area of relatively high atmospheric pressure compared to the surrounding environment, without being a closed circulation. It is associated with an area of maximum anticyclonic curvature of wind flow. The ridge originates in the center of an anticyclone and sandwiched between two low-pressure areas, and the locus of the maximum curvature is called the ''ridge line''. This phenomenon is the opposite of a trough. Description Ridges can be represented in two ways: * On surface weather maps, the pressure isobars form contours where the maximum pressure is found along the axis of the ridge. * In upper-air maps, geopotential height isohypses form similar contours where the maximum defines the ridge. Related weather Given the direction of the winds around an anticyclonic circulation and the fact that weather systems move from west to east: *ahead of an upper-ridge, the airflow that comes from the polar regi ...
