Cyclone Giovanna
Intense Tropical Cyclone Giovanna was a powerful tropical cyclone that affected Madagascar. Giovanna was the ninth tropical depression, seventh named storm and third tropical cyclone of the 2011–12 South-West Indian Ocean cyclone season. Giovanna was blamed for 35 deaths along the Madagascar coast, La Réunion, and Mauritius, and it was the first intense tropical cyclone to impact Madagascar since Cyclone Bingiza in 2010–11 South-West Indian Ocean cyclone season, February 2011. Meteorological history Cyclone Giovanna developed from a tropical wave over the Indian Ocean heading to the southwest on February 7. The tropical disturbance soon developed into Tropical Depression 09 on February 9. On the same day, the Joint Typhoon Warning Center upgraded the system, giving it the designation "12S". The storm intensified into a moderate tropical storm and was given the name Giovanna. On February 10, Giovanna continued to strengthen into a severe tropical storm. Later the ...

Wind Shear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyclones In Madagascar
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 ...

Cyclone Batsirai
Intense Tropical Cyclone Batsirai was a deadly tropical cyclone which heavily impacted Madagascar in February 2022, becoming the strongest tropical cyclone to strike Madagascar since Cyclone Enawo in 2017. It made landfall two weeks after Tropical Storm Ana brought deadly floods to the island country in late January. The second tropical disturbance, the first tropical cyclone, and the first intense tropical cyclone of the 2021–22 South-West Indian Ocean cyclone season, Batsirai originated from a tropical disturbance that was first noted on 24 January 2022. It fluctuated in intensity and became a moderate tropical storm on 27 January 2022, after which it unexpectedly rapidly intensified into an intense tropical cyclone. It then weakened and struggled to intensify through the coming days due to present wind shear and dry air, where it weakened after some time. Afterward, it entered much more favorable conditions, rapidly intensified yet again to a high-end Category 4 cyclone on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Enawo
Intense Tropical Cyclone Enawo was the strongest tropical cyclone of the 2016–17 South-West Indian Ocean cyclone season. Enawo was the strongest tropical cyclone to strike Madagascar since Cyclone Gafilo, Gafilo in 2004, killing 78 people and causing $400 million in damages. Forming as a moderate tropical storm on 3 March, Enawo initially drifted and intensified slowly. It strengthened into a tropical cyclone on 5 March and further an intense tropical cyclone on 6 March. Enawo made landfall over Sava Region on 7 March just after reaching peak intensity, and it emerged back into the Indian Ocean as a post-tropical cyclone, post-tropical depression late on 9 March, before dissipating two days later. The most severe impacts were seen in the districts of Antalaha and Maroantsetra. Meteorological history A monsoon trough started to persist west of Diego Garcia in late February 2017 as the Madden–Julian oscillation (MJO) over the Indian Ocean grew more noticeable. On 2 March, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. There is a suggestion that climate change may be increasing the hazard of storm surges. Some theorize that as extreme weather becomes more intense and sea level rises due to climate change, storm surge is expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fujiwhara Effect
The Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiw(h)ara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices move around each other and close the distance between the circulations of their corresponding low-pressure areas. The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described the effect. Binary interaction of smaller circulations can cause the development of a larger cyclone, or cause two cyclones to merge into one. Extratropical cyclones typically engage in binary interaction when within of one another, while tropical cyclones typically interact within of each other. Description When cyclones are in proximity of one another, their centers will circle each other cyclonically (counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere) about a point between the two systems due to their cyclonic wind circulations. The two vortices will be attra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anticyclone
An anticyclone is a weather phenomenon defined as a large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere as viewed from above (opposite to a cyclone). Effects of surface-based anticyclones include clearing skies as well as cooler, drier air. Fog can also form overnight within a region of higher pressure. Mid-tropospheric systems, such as the subtropical ridge, deflect tropical cyclones around their periphery and cause a temperature inversion inhibiting free convection near their center, building up surface-based haze under their base. Anticyclones aloft can form within warm-core lows such as tropical cyclones, due to descending cool air from the backside of upper troughs such as polar highs, or from large-scale sinking such as a subtropical ridge. The evolution of an anticyclone depends upon variables such as its size, intensity, and extent of moist con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landfall
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 the ...

East Africa Time
East Africa Time, or EAT, is a time zone used in eastern Africa. The time zone is three hours ahead of UTC ( UTC+03:00), which is the same as Moscow Time, Arabia Standard Time, Further-eastern European Time and Eastern European Summer Time. As this time zone is predominantly in the equatorial region, there is no significant change in day length throughout the year and so daylight saving time is not observed. East Africa Time is observed by the following countries: * * * * * * * * * See also *Moscow Time, an equivalent time zone covering Belarus, Turkey and most of European Russia, also at UTC+03:00 *Arabia Standard Time, an equivalent time zone covering Bahrain, Iraq, Kuwait, Qatar, Saudi Arabia and Yemen, also at UTC+03:00 *Eastern European Summer Time, an equivalent time zone covering European and Middle Eastern countries during daylight saving, also at UTC+03:00 *Israel Summer Time, an equivalent time zone covering the State of Israel during daylight saving, also at U ...
