2017 North Indian Ocean Cyclone Season
The 2017 North Indian Ocean cyclone season was a below average yet deadly season in the annual cycle of tropical cyclone formation. This season produced only three named storms, of which one only intensified into a very severe cyclonic storm. The North Indian Ocean cyclone season has no official bounds but cyclones tend to form between April and December with the two peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began with the formation Cyclone Maarutha on April 15 and ended with the dissipation of a deep depression on December 9. The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean – the Arabian Sea to the west of the Indian subcontinent, abbreviated ''ARB'' by the India Meteorological Department (IMD); and the Bay of B ...

Cyclone Mora
Severe Cyclonic Storm Mora () was a moderate but deadly tropical cyclone that caused widespread devastation and severe flooding in Sri Lanka, Andaman and Nicobar Islands, Bangladesh, Myanmar and Northeast India in May 2017. The second named storm of the 2017 annual cyclone season, Mora developed from an area of low pressure over the southeastern Bay of Bengal on May 28. Mora reached peak strength with maximum sustained winds of . The cyclone made landfall near Chittagong on the morning of May 30 and steadily weakened, dissipating early in the morning on May 31. Across its path, Mora dropped a large amount of rain, including 225mm of rainfall in Chittagong and northeast India. The storm is estimated to have caused damages nearing US$300 million. The name ''Mora'', suggested by Thailand, which refers to ''star of the sea'' or ''sea star''. Meteorological history In late May 2017, an area of convection began to organize in the Bay of Bengal. Favorable conditions, characterized by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Depression (weather)
In meteorology, a low-pressure area (LPA), low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area. 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 forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper troughs, which form half of a Rossby wave within the Westerlies (a trough with large wavelength that extends through the troposphere). * A s ...

Storm Surge
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Other factors affecting storm surge severity include the shallowness and orientation of the water body in the storm path, the timing of tides, and the atmospheric pressure drop due to the storm. As extreme weather becomes more intense and the sea level rises due to climate change, storm surges are expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, like coastal dunes or mangroves, improving coastal construction practices and building social strat ...

Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in Atmosphere of Earth, atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the Wet season, rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the Monsoon#Africa (West African and Southeast African), West African, Asian–Australian monsoon, Australian, the North American monsoon, North American, and South American monsoons. The term was first Glossary of the British Raj, used in English in British India and neighboring countries to refer to the big seasonal winds blowin ...

Saffir–Simpson Scale
The Saffir–Simpson hurricane wind scale (SSHWS) is a tropical cyclone intensity scale that classifies hurricanes—which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms—into five categories distinguished by the intensities of their sustained winds. This measuring system was formerly known as the Saffir–Simpson hurricane scale, or SSHS. To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at above the surface of at least 74 mph (64 kn, 119 km/h; Category 1). The highest classification in the scale, Category 5, consists of storms with sustained winds of at least 157 mph (137 kn, 252 km/h). The classifications can provide some indication of the potential damage and flooding a hurricane will cause upon landfall. The Saffir–Simpson hurricane wind scale is based on the highest wind speed averaged over a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
