Cyclone Onil
Severe Cyclonic Storm Onil (India Meteorological Department designation: ARB 03; Joint Typhoon Warning Center designation: 03A) was the first tropical cyclone to be named in the northern Indian Ocean. Forming out of an area of convection several hundred kilometres southwest of India on October 1 2004, Cyclone Onil quickly attained its peak intensity on October 2 with winds of and a barometric pressure of 990 mbar (hPa; ). However, dry air quickly entered the system, causing it to rapidly weaken to a depression just off the coast of Gujarat, India. Over the following several days, the system took a slow, erratic track towards the south-southeast. After turning northeastward, the system made landfall near Porbandar on October 10 and dissipated shortly thereafter. Throughout southeastern Pakistan and northwestern India, thousands of residents were evacuated prior to the cyclone's arrival. In these areas, the storm produced moderate to heavy rainfall, peaking at in T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2004 North Indian Ocean Cyclone Season
The 2004 North Indian Ocean cyclone season was the first in which tropical cyclones were officially named in the basin. Cyclone Onil, which struck India and Pakistan, was named in late September. The final storm, Cyclone Agni, was also named, and crossed into the southern hemisphere shortly before dissipation. This storm became notable during its origins and became one of the storms closest to the equator. The season was fairly active, with ten depressions forming from May to November. The India Meteorological Department designated four of these as cyclonic storms, which have maximum sustained winds of at least averaged over three minutes. The Joint Typhoon Warning Center also issued warnings for five of the storms on an unofficial basis. In early May, two tropical storms formed on opposite sides of India. The first formed on May 5 and meandered while intensifying, dropping in Aminidivi in the Lakshadweep group offshore western India, which was the highest daily rainf ...

Low-pressure Area
In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis force, Coriolis forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the Atmosphere of Earth, atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In Meteorology#Dynamic meteorology, meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper Trough (meteorology), troughs, which form half of a Rossby wave within the Westerlies (a trough (meteorology), trough with la ...

Tropical Cyclones In India
India is a country in the north of Indian Ocean that is the most vulnerable to getting hit by tropical cyclones in the basin, from the east or from the west. Background India is a country in South Asia that is bounded by the Arabian Sea, the Indian Ocean and the Bay of Bengal, while it shares land borders with Bangladesh, Bhutan, China, Myanmar, Nepal and Pakistan. India is also located within the vicinity of Sri Lanka and the Maldives, while its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar and Indonesia. On average around 2 to 4 tropical cyclones impact India every year, while most of these tropical cyclones impact the east coast of Indian states of West Bengal, Odisha, Andhra Pradesh, Tamil Nadu. The West Coast of India is less prone to cyclones with one cyclone out of 2 to 4 hits the west coast with majority of them attacking the state of Gujarat, Maharashtra, Goa, Karnataka and Kerala.

Tropical Cyclones In Pakistan
Pakistan lies in the temperate zone. The climate is generally arid, characterized by the extreme southwestern part of the country where Gwadar and Karachi are the main port cities. Though cyclones are rare in the Arabian sea which a part of North Indian Ocean, cyclones that form in this sea mostly move towards Western India rather than Pakistan. Cyclones in the Arabian sea form mostly from May till June and then from September till October, monsoon season plays a vital role for the formation of cyclone in this basin. Tropical storms that hit Pakistan are mostly remnants by the time reach Pakistan or make landfall in south eastern Sindh which is not very much populated they rarely move towards the Balochistan coast. Background Pakistan has a 1,046-kilometre (650 mi) coastline along the Arabian Sea and the Gulf of Oman in the extreme south western part of the country where Gwadar is the main port city. Though cyclones are rare in the Arabian sea which is a part of North Indian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Wettest Tropical Cyclones By Country
This is a list of wettest tropical cyclones by country, using all known available sources. Data is most complete for Australia, Cuba, Dominican Republic, Japan, Hong Kong, Mexico, Taiwan, Micronesia's Yap and Chuuk, and the United States, with fragmentary data available for other countries.

United States Dollar
The United States dollar ( symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pakistani Rupee
The Pakistani rupee ( ur, / ALA-LC: ; sign: Re (singular) and Rs (plural); ISO code: PKR) is the official currency of Pakistan since 1948. The coins and notes are issued and controlled by the central bank, namely State Bank of Pakistan. In Pakistani English, large values of rupees are counted in thousands; lakh (100,000); crore (ten-millions); Arab (billions); kharab (100 billion). Numbers are still grouped in thousands (123,456,789 rather than 12,34,56,789 as written in India) History The word ''rūpiya'' is derived from the Sanskrit word ''rūpya'', which means "wrought silver, a coin of silver", in origin an adjective meaning "shapely", with a more specific meaning of "stamped, impressed", whence "coin". It is` derived from the noun ''rūpa'' "shape, likeness, image". ''Rūpaya'' was used to denote the coin introduced by Sher Shah Suri during his reign from 1540 to 1545 CE. The Pakistani rupee was put into circulation in Pakistan after the dissolution of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Onil TRMM Eye
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formation and ...

Dvorak Technique
The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared satellite images. Within the Dvorak satellite strength estimate for tropical cyclones, there are several visual patterns that a cyclone may take on which define the upper and lower bounds on its intensity. The primary patterns used are curved band pattern (T1.0-T4.5), shear pattern (T1.5–T3.5), central dense overcast (CDO) pattern (T2.5–T5.0), central cold cover (CCC) pattern, banding eye pattern (T4.0–T4.5), and eye pattern (T4.5–T8.0). Both the central dense overcast and embedded eye pattern use the size of the CDO. The CDO pattern intensities start at T2.5, equivalent to minimal tropical storm intensity (40 mph, 65 km/h). The shape of the central dense overcast is also con ... [...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] |
